Abstract

The invention relates to the technical field of steel and iron smelting, in particular to a continuous casting method of a high-carbon steel plate blank. The method comprises the following steps: the casting superheat degree of the high-carbon steel plate blank is controlled within 10-20 DEG C by low superheat degree; the low-pulling-speed continuous casting is performed for the high-carbon steel plate blank, and the pulling speed is controlled within 0.9-1.1 m / min; the aerial fog cooling is performed for the high-carbon steel plate blank; the taper of a crystallizer is controlled according to variable taper, wherein the alkalinity of covering slag in the crystallizer is controlled within 0.93-0.99; the melting point of the covering slag is not higher than 1050 DEG C; and the viscosity of the covering slag is not higher than 0.140 pa.s. The method reduces the large surface and angle stress, enhances the solidification uniformity of a blank shell, reduces the surface crack generation rate of the plate blank, and improves the center segregation level.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a high-carbon steel slab continuous casting method. Background technique [0002] High-carbon steel is often used to manufacture mechanical equipment such as gears, springs, and saw blades. The banded structure in high-carbon steel is different from the deformation of the steel matrix, and forms a source of fatigue damage under the action of alternating stress, and the banded structure is usually related to the The slab center segregation is closely related. The high carbon steel slab center segregation level in the prior art is often low. Therefore, the workpiece is subjected to periodic alternating stress during service, which is prone to fatigue damage, which leads to the failure of the workpiece, and , Surface depressions and corner cracks appear in high carbon steel slabs. [0003] In addition, due to the relatively high carbon content and relatively low liq...
