Why does the surface of steel shot appear silver and bright and does not rust?

　　Steel shot has moderate hardness, strong toughness, impact resistance, long service life, good elasticity, fast cleaning speed, low consumption, no breakage, but careful customers will find that the surface always has a bright silver color and is not easy to rust. Why is this?

　　The heated steel shot slips into the orifice plate of the fluidized bed through the slide pipe at the upper right of the fluidized bed, and the cold wind with wind pressure and wind speed flows out from the small hole of the orifice plate of the fluidized bed. The cold wind makes the steel shot jump into a semi-suspended state, and at the same time takes away the heat, making it quickly cooled below the MS point and forming a quenching structure. The other end of the air duct is connected to the blower, and the other end of the exhaust hood is connected to the dust collector. The fluidized bed is used to air-cool the steel shot to achieve the purpose of quenching, so that the subsequent drying, rust, environmental pollution and other problems will be solved. Real-time and stepless flow control of the flow is achieved by using the electromagnetic effect on the steel shot. It fundamentally avoids the problems of known valves being stuck, unable to be opened or closed after being used for a period of time. In the process of flow control, there is no wear on the valve plate; and it does not need manual opening, which is beneficial to use in automation systems; it is easy to install, and when a fault occurs, due to its unique structural characteristics, it can be maintained and replaced without disassembly.

　　Steel shots are used to solve the problems of easy rust, low impact resistance and low friction resistance in the shot blasting metal surface treatment process, and provide corresponding processing methods and equipment; the equipment used is simple, easy to operate, and the process is short, which can effectively improve productivity. Equipment, industrial cans and auto parts, hardware products, industrial rolling rods and other fields and occasions for surface cleaning, deburring, rust removal, polishing and surface strengthening. Mounting flanges are arranged at both ends of the shot tube, and electromagnetic coils are arranged on the shot tube.

　　The flow control device overcomes the defects in the existing technology, and uses the electromagnetic effect on the steel shot to achieve real-time and stepless flow control of the flow.
