The key factors of performance of grinding steel ball

    The key factor of grinding steel ball’s lifespan decided by its manufacturing process. if there is an existing flaw inside or surface of the steel ball. for example shrinkage cavity, crack, transgranular, etc. It not only can reduce the performance of steel ball, Even will cause the steel ball to break. So, we must formulate the reasonable forging, casting, and heat treatment process during steel ball production.
    For example, high-chromium cast-iron ball should adopt vertical casting and rational use of cold iron, Strictly control the pouring temperature and other measures, This can make the ball in casting solidification sequence and feeding conditions, The internal organization of density is obtained, And weakened the phenomenon of coarse grains, The heat treatment of steel ball decide its realization of its mechanical properties and the distribution of the carbide morphology.
    Due to the steel ball of the ingredients contain a certain amount of chromium and other alloying elements,  So how to give full play to come out the role of the alloy elements to form carbide hard spots, It is a factor to formulate a heat-treatment process.
