Thermophysical analysis of the processes of solidification, cooling, and heating of ingots (castings)

This article investigates the thermal state of a plate ingot in the joint heat-engineering process of its preparation for plastic deformation by a technological procedure as used on the scale of metallurgical production, which includes shaping and cooling of the ingot in the ingot mold, cooling in air, and subsequent heating in some appropriate plant. A numerical model is suggested for the process of heating and cooling an incompletely solidified ingot. The model is used to determine the temperature distribution throughout the ingot during the hot charging and crystallization processes. Relations between the heating and cooling regimes are established by proceeding from the amount of liquid phase and the heat content of hotcharged ingots.
