It is reported that the contribution of thermally-induced deformations of a machine tool may exceed 50% of the total machining error .
Thus, the technology completely eliminates the use of re -heating furnace and forms a direct transfer mechanism for the hot billets from the continuous casting machine to the rolling mill directly. The process leads to complete elimination of use of fuel (furnace oil or gas or coal) required for heating of billets in the re -heating.
