Bearing steel mainly used in the manufacture of rolling and the Rolling Ring. As bearing should have long-life, high-precision, low-calorie, high-speed, high rigidity, low noise, high wear-resistance and other characteristics, bearing steel demand should have: high hardness, uniform hardness, high elastic limit, high-contact fatigue Strength, the necessary toughness, a certain hardenability, in the atmosphere of lubricants in the corrosion resistance. In order to achieve these performance requirementsCylindrical Roller Bearing , bearing steel uniformity of the chemical composition, content and non-metallic inclusions type, size and distribution of carbide, decarbonization, and so demanding. Bearing steel to the overall high-quality, high-performance and multi-species direction. Steel and bearing the characteristics of the environment is divided into: chromium bearing high-carbon steel, bearing steel carburizing, high-temperature bearing steel, stainless steel and bearings for the special bearing materials. To meet the high-temperature, high-speed, high capacity, corrosion resistance, anti-radiation requirements need to develop a series of special performance of the new bearing steel. In order to reduce the oxygen content bearing steel, smelting development of a vacuum, ESR, electron beam melting, and other bearing steel smelting technology. And large quantities of bearing steel smelting by the electric arc furnace smelting, to develop into various types of early furnace and boiler, refining. At present, the use of a capacity of more than 60 tons of early furnace + LF / VD or RH + + continuous casting and rolling bearing steel production process to achieve high-quality, high efficiency, low-power purposes. In the heat treatment process, from cars hearth furnace, a Bell-type heaters for the development of controlled atmosphere annealing furnace heat treatment. At present, continuous heat treatment furnace up to 150 m, processing production of steel ball bearings of the organizations stability and uniformity, the decarbonization of the small, low energy consumption. Since the 1970s, with economic development and industrial technological progress, expand the scope of application of bearings, and the development of international trade, and promote international standards of the bearing steel and new technology, new equipment and new technology development and application of efficiency High, high-quality, low cost of supporting technical and technological equipment have emerged. and have all built a high degree of cleanliness, high-quality bearing steel production line so that the rapid increase in the output of steel, steel quality and a substantial increase fatigue life. and bearing steel production of the oxygen content down to below 10 ppm. The late 1980s, Japan's Sanyo Special Steel Company's advanced level of 5.4 ppm, reached a vacuum remelted bearing steel level. Bearing contact fatigue life of the uniformity of Steel is very sensitive. Improve the cleanliness of (reduction of impurities in steel elements and inclusion content), to steel in the non-metallic inclusions and uniform distribution of small carbide, steel bearings to increase the contact fatigue life.

1. In the course of inkjet nozzle found after a minor phenomenon to plug the keys do not hesitate to suspend the print job, and then use manual pump or vacuum cleaner so that ink from the nozzle out a nozzle cleaning, washing after plastic squeeze bottles to be used to the nozzle Spray the surface of some cleaning fluid wash away the residue

Remain ink.

Note: when using manual pump not excessive force, otherwise they will be in too much pressure and damage to nozzle.

2. Decisively and promptly and thoroughly deal with the nozzle slightly to plug in the printing process to maintain long nozzle best working conditions is very important!

3. In addition, it is also necessary to carefully Wide Format Printer Wide-Format Printer check the situation and find sprinkler nozzle plug the reason.

In the course of the frequent inkjet nozzles to plug the treatment of

1. Printing Press to suspend operations, and then the button nose to the left of the mobile cleaning position.

2. Power to maintain equipment in the open,

3. Will head for Mexico on the tube (from cans of Mexico) pulled out, and then use glass syringes for clean extraction of cleaning nozzle,: 40 ml each with cleaning fluid every 10 minutes, a total of three to four times.

4. After re-plug for the cleaning of ink and liquid level sensors signal line, and then suspended prior to the print job.

More effective method of dealing with little or no effect at the time being the treatment of

1. Nozzle will be removed from the nozzle tray removal.

2. In a clean glass container (such as: beaker) into the appropriate special cleaning fluid to Add to head submerged nozzle at the bottom after 2 ~ 3 mm suitable, and then use cling film will be sealed glass containers (anti-gray) standing one day Above.

Note: the top of the nozzle not signal interface contact cleaning fluid, otherwise they will be damaged nozzle.

3. After soaking nozzle, in the printer nozzle for washing into the amount of special cleaning fluid, then head into the bottom of cleaning fluid Submerged about 2 ~ 3 mm, and then start cleaning, the choice for head cleaning, if you use the general Ultrasonic cleaning is must strictly control

, To prevent damage to nozzle.

Note: continuous use for cleaning do not have to wash more than three times.

4. Glass from 40 ml syringes for cleaning fluid, from the top of the head of the Mexican port for the injection of Wang Li, pay attention to observe the water from the nozzle out of state, if all the waterline are allowed, effective cleansing that, the nozzle can Continue to use (the premise: Circuit and piezoelectric crystals

Are intact), if there are still some water spray distortion, according to the first two or three steps to do two or three times.

Equipment is expected to more than 48 hours when not to use the approach

If the device is expected to more than 48 hours not to use, must be in the ink nozzles clean, otherwise the ink nozzles will be gradual because of volatile solvents and stem end, the nozzle will be serious and even cause irreversible damage. Approach as follows:

1. Close inkjet machine's power.

2. Will be moved to the extreme left nose clean position, the bottom-head in a corrosion-resistant containers used to hold waste water cleaning.

3. Glass syringe or direct pouring out of ink in the ink tank, and then use special cleaning fluid will be washed clean of ink tank.

4. Will head for Mexico on the tube (from cans of Mexico) pulled out, and then use glass syringes from 40 ml cleaning fluid for cleaning guns, so a total of 2. Do not head in the final remnants of cleaning fluid blown clean, we must remain adequate internal cleansing of the nozzle, because the cleaning fluid nozzles

Moisture can play a role.

Will be dealt with the nozzle into a clean corrosion-resistant containers and sealed (by cling film on the good) can be stored up after a month or so.

Impurities in the steel and mechanical properties of parts failures and the ability of impurities in the type, nature, number, size and shape, but usually have lower toughness, plastic and the role of fatigue life. With the inclusion of increasing size, and then reduce fatigue, and the higher the tensile strength of steel, increased to reduce the trend. Higher oxygen content in steel (oxide inclusion increase), bending fatigue and exposure to high stress and fatigue life in under also will be reduced. Therefore, under high stress in the work of the bearing parts, Ball Bearings steel manufacturers to reduce the oxygen content is necessary. Some studies show that the steel in the MnS inclusions, the elliptical shape of a sphere, but also against the larger parcels oxide inclusions, the lower its fatigue life may also be less affected or even useful, it can Ceramic Bearing control leniency. 2 affect bearing life of the material in order to control the factors that affect the life of the bearing material factors in its best state, first of all need to control the hardening of steel before the original organization, the technical measures can be taken are: high temperature (1050 ℃) Austenite of speed 630 ℃ to cold temperature, such as normalizing access to pseudo-eutectoid fine pearlite, or cold to 420 ℃, such as temperature, access to bainite organizations. Heat can also be forging rolling RTA, access to fine particulate pearlite organizations, to ensure that the carbon steel in small and evenly distributed. This original state of the Organization of the hardening Austenite heating, in addition to integration into the austenite in the carbide, undissolved Carbide will gather into a fine grit. When the original Roller Bearings organization of a certain time, the carbon content of quenching martensite (hardening of the heated carbon austenitic), retained austenite volume and undissolved mainly depends on the hardening of carbide heating temperature and keep time With quenching temperature increased (some time), in steel decrease in the number of undissolved carbide (carbon content higher quenching martensite), the increase in the number of retained austenite, the hardness of the first with the hardening of the higher temperature increase, Reached its peak and then with increasing temperature lower. When quenching a certain temperature, with the extension of austenitic, did not reduce the amount of dissolved carbon, the increase in the number of retained austenite, hardness increased, a longer time, this trend is slowing. When the original carbide in small, for easy integration into the austenitic carbide, the so-quenching after the hardness and a shift to lower the temperature in a relatively short time of austenite.

Q for the ink-on-demand technology that is controlled by the head of the droplet size and shape of the state, and to control the size of to complete the color combination. Mainly Angels, SALSA, and so on. NEWSTAR Korea also used the nozzle technology.

P Lianxugongmo techniques, namely the continuous spray guns to , but in the head with a deflection in the media field, by changing the size of Wide Format Printer the magnetic field to control the drop. Lianxugongmo technology for the Mexican system for more complex, difficult to maintain, mainly in blue-and-wide application.

Piezoelectric head of the Wide-Format Printer main apply to solvent inks can be directly inkjet ordinary light cloth, it became the preferred outdoor production. So large-scale inkjet machines using such technology. Freedom of choice because of supplies, outdoor production of the lowest cost, because of the ink solvents with a strong corrosive, permeable to

PVC light boxes in the internal cloth, weathering of up to about 2002. However, another to warn the user that the material of choice for weathering the impact is greater, by Daogua-coated fabric or thickness of the paste more than 0.45 ml of fabrics, the weathering of the best, and the other coated fabrics Weatherability also higher than those without

Coated fabrics.

However, large-scale inkjet machine because of huge investment, and cost recovery slow. Thus gradually shifted investment hot spot for small and medium-sized inkjet, the recently launched KM-S350 limit the use of machine guns (British XRRA nozzle technology), a professional outdoor models, but imitation is the principle of machine-produced,

Including the use of automated systems for , the head professional head of the solvent, so it card for the main outdoor models. Long life is due to head design, there is no need regular replacement nozzle and reduce the factors arising from machine malfunctions. Therefore can be widely applied to small and medium-sized outdoor advertising production, costs

Much lower than other devices. And the commitment by the machine vendors within a year of major quality problems have machines to replace machines can be used as the advertising agency business development preferred.

Conclusion: The large jet aircraft such as inkjet technology (by the United States and KM-S350), due to low cost, speed, 4,000 square meters per month, low investment and high returns, and become a mainstream outdoor advertising production models.
