When cast steel balls are used in mills, the density directly affects the quality of the steel balls, and the use time will also vary greatly, so density is quite important in various index parameters. So, how to control the density of cast steel balls?
When cast steel balls are used in mills, the density directly affects the quality of the steel balls, and the use time will also vary greatly, so density is quite important in various index parameters. Steel Balls share how to control the density of cast steel balls.
In the production of casting steel balls, casting balls due to the use of traditional sand casting process, so the inside and surface of the steel ball will inevitably produce pores and sand inclusion, but also there are casting waste edges, etc., so the density is generally below 7.75g/cm³, the new type of hot-rolled steel ball, using square billet hot rolling extrusion production of round steel as the production raw material, while the hot-rolled ball production process through roll forming extrusion, so the density of hot-rolled balls is generally greater than 7.85 g/cm3 or more.
Through the above comparison of the density of finished steel balls, it can be seen that the steel ball production process is different, the raw materials used are different, and the density of steel balls after manufacturing is different. Among steel ball products, the production rate with high ball density of the same size is large, and the productivity of small density is small.
