Production of Steel Castings in Cylindrical Molds

Resumo

The continuous casting of steel is simulated by means of Sn–Pb alloy on two models of the mold. One of the models, which has been patented, has a closed loop for two-phase coolant circulation. The following characteristics are compared: the cooling of the two castings; the temperature of the models’ cylindrical walls; the thickness of the crust formed; the structure of the castings; and their surface quality. The results are used in simulation of the thermal processes in a model with the continuous supply of an increasing heat flux and the correction of the processes for steel casting.
