CONTROL OF SOLIDIFICATION PROCESS DURING CONTINUOUS CASTING OF STEEL

An investigation has been carried out into the "metallurgical criterion" of the slab solidification during continuous casting. The effect of following variables on the metallurgical criterion has been studied by the mathematical model of heat transfer: casting speed, spray water intensity, water distribution in spray zone, superheat in tundish, convection in liquid pool and temperature of spray water. Considering these factors, a nomogram of the productivity related to slab thickness, casting speed, spray water intensity and depth of liquid pool was prepared so as to selecte reasonably the technological parameters and to control scientifically the operation.
