Abstract
A process for controllng the withdrawal of a casting from a cooled, horizontal, continuous casting mold involves withdrawing the casting from the mold in a series of steps, between which steps the casting is pushed back by a partial step to insure the welding together of casting sections. A melt breakthrough of the casting skin is prevented by measuring the expansion or contraction of a wall of the mold in contact with the casting and controlling the withdrawal of the casting in response thereto.
