Profit (in foundry ) - the upper part of a steel ingot (casting), the dimensions of which extend beyond the required dimensions. Its purpose is to feed the casting with liquid metal melt during its solidification. As a result, the inevitably occurring shrinkage shell is formed not in the casting itself, but in the thickness of profit. Before the ingot is fed for rolling, the entire excess volume of the profit metal is cut off [1] [2] [3] .
In the modern technical literature, one can find quantitative results of mathematical modeling of the physical processes of shrinkage shell formation. As a rule, the diameter of profit depends on the diameter of the casting, and the height of profit - on the height of the casting [4] .
