900 ball mill Gaoluo alloy steel ball steel section accessories manufacturer

Song, cast steel ball (casting grinding ball) is a steel ball manufacturer that uses an intermediate frequency electric furnace to heat scrap steel, scrap iron and other scrap materials to fully melt the furnace materials. During the melting process of the furnace materials, an appropriate amount of precious metal alloys (such as ferrochrome) are added. , ferromanganese, ferrovanadium, etc.) into the furnace for chemical composition quenching and tempering. After the temperature of the molten iron reaches
Song Dynasty ℃
or above and meets the requirements of the process regulations, the qualified molten iron is poured into the steel ball mold or steel ball production line. in the mold. That is, the steel balls produced by casting and smelting are called cast steel balls (cast grinding balls).
% Songti cast steel balls are divided into high chromium alloy cast balls, multi-component alloy cast balls and low chromium alloy cast balls according to their materials.
% Song Dynasty 2. Forged steel balls are steel balls produced by steel ball manufacturers through direct high-temperature heating and then forging. It does not require melting and casting, but is just forged, so it is called forged steel ball.

宋体 and the steel balls are made by high-temperature forging. Although the surface hardness of some forged steel balls (
宋体) can reach
宋体 or above (quenching layer Only about
宋体mm), due to the poor hardenability of the forged steel ball material, the hardness of the core is generally only
宋体 (as the diameter of the steel ball increases, the hardenability becomes worse). Under normal circumstances, forged steel balls are often water quenched.
