Continuous casting also called strand casting is the process whereby molten metal is solidified into a semifinished billet bloom or slab for subsequent rolling in the finishing mills Prior to the introduction of continuous casting in the 1950s steel was poured into stationary molds to form ingots Since then continuous casting has evolved to achieve improved yield quality

4 If using the semi-autogenous mill the large ball with the diameter of 100-150mm can not only reduce the unit consumption but also increase the handling capacity but as a result of the casting process defects the breakage rate of cast ball is much higher than the forged ball
