Products of different size and hardness are used in different processes

Date:2018-04-13 Author: Click:

The molten steel is dissolved in gray iron casting and then formed into a small ball by high pressure water injection. The formed pellets are heated again to purify the homogenate and then quenched. Drying pill body inside the furnace after quenching and reheating tempering in order to achieve the proper hardness, tempering treatment of steel shot through mechanical screen is sorting into the SAE standard 11 grade for shot blasting equipment. Products of different size and hardness are used in different processes, such as surface strengthening.

Is a kind of ideal abrasive products in many castings deoxidization process, using steel shot blasting effect is good, steel shot is also widely used in iron and steel workpiece to scale and rust removal treatment before. Steel balls are classified into steel balls, cast iron balls, glass balls and other steel balls with different hardness. The hardness of steel balls is HRC40 ~ 50, which can be increased to HRC57 ~ 62 by machining some hard metals. They have good toughness, service life is several times that of cast iron pellets, and are widely used.

The hardness of cast iron pellets is hrc58-65. These steel pellets have high hardness and are very brittle in refrigeration. It is mainly used in places where high strength of shot blasting is required. The hardness of glass pellets is lower than that of the previous two types, mainly used in stainless steel, titanium, aluminum, magnesium and other situations where iron pollution is not allowed. It can also be used for the second treatment after steel shot blasting to remove iron pollution and reduce the roughness of parts surface.

Steel shot is a kind of commonly used metal workpiece processing material, steel shot tightly organized, granularity and deal with the surface of metal workpiece with steel shot can have the effect of adding metal workpiece surface pressure, can well improve the anti-fatigue ability. Using steel shot processing metal surface have the characteristics of speediness, steel shot and steel shot have moderate strength, good elasticity, internal Angle and complex shape workpiece can be evenly clear quickly, shorten the time of surface treatment, improve the work efficiency is a kind of very good surface treatment materials.
