Centrifugal casting is a kind of very important casting process, it is through it to molding, many artifacts in order not to affect the quality of rolling, whether before or after operation to carry on the comprehensive check.The results show that the centrifugal casting roll. The combination of slag layer of defects, is there any way to avoid it?Centrifugal casting roll generally appear in the outer layer of slag problem between molten steel and molten iron core department, so want to thoroughly solve the problem must start from raw materials, and through the improvement of technology and management, to further guarantee the final quality.To control the centrifugal casting furnace charge first, to improve the purity of steel water;If it is of high melting point alloy material, had better be to be broken before you join in furnace.In centrifugal casting process, must hold good elements, such as temperature, time, this is the most basic conditions to obtain high quality castings.Otherwise, if we can improve the end cover mould, such as high strength, coating strength that to improve the effect will be more obvious.
