Title: Continuous casting method of steel slab
Inventor: OHASHI WATARU
IPC: B22D11/16
Filed: 1985-02-20
Abstract: PURPOSE:To improve remarkably the internal quality and particularly central segregation of a slab by exerting rolling down force to the slab advancing in a continuous casting machine in the position where the thickness of the solidified shell of the slab satisfies the specific equation relating to the thickness of the solidified shell and the thickness of the slab. CONSTITUTION:The slab 1 is drawn by guide rolls 2, etc. and advances in the direction (a) while the rolling down force is exerted to the slab 1 in the thickness direction thereof by driving rolls 3 having backup rolls 4. The solidified shells 11 are formed to the slab 1 from the surface part and the molten steel remains while the molten steel is held enclosed by the shells 11, by which an unsolidified part 12 is formed. The slab 1 is rolled down in the thickness direction thereof by the rolls 3 and the upper and lower shells 11 are thereby press-welded in the position of the range where the shells 11 satisfy the equation (h is the thickness of the solidified shell on one side of the slab in the thickness direction and D is the thickness of the slab). The increased segregation owing to the flow of the unsolidified steel as a result of the rolling reduction and the worry about the press-weldability of the solidified shells to each other are thoroughly eliminated by forming a crater end 13 in the above- mentioned manner.
