本发明公开了一种提高板坯轻压下效率的方法,包括对所述连铸机辐缝进行测量,根据测量结果将0段-2段的辐缝精度控制在第一设定值的-0.5至0mm的范围内；对所述连铸机辐缝进行测量，根据测量结果对3段-轻压下前的1段的辐缝精度进行控制;对所述连铸机辐缝进行测量，根据测量结果将对实施轻压下的2个或者3个段辐缝精度进行控制；对所述连铸机辐缝进行测量,根据测量结果对轻压下后的1段-14段辐缝精度进行控制。本发明提供的提高轻压下效率的方法，有效解决了传统轻压下工艺压下率有限的缺点，改善了板坯中心偏析，同时降低了内部裂纹的发生，使得最终产品质量得到显著提升。

The invention discloses a method for improving the efficiency of light reduction of a slab, which includes measuring the spoke gap of the continuous casting machine, and controlling the accuracy of the spoke gap of the 0 segment-2 segment at a first set value according to the measurement result. Within the range of 0.5 to 0 mm; measure the spoke gap of the continuous casting machine, and control the accuracy of the spoke gap of the third segment-the first segment before light reduction according to the measurement results; measure the spoke gap of the continuous casting machine, According to the measurement results, the accuracy of the 2 or 3 segments of the light reduction will be controlled; the spoke gap of the continuous casting machine will be measured, and the accuracy of the 1-14 segment after the light reduction will be measured according to the measurement results Take control. The method for improving the efficiency of light reduction provided by the present invention effectively solves the shortcomings of the limited reduction rate of the traditional light reduction process, improves the center segregation of the slab, reduces the occurrence of internal cracks, and significantly improves the quality of the final product.
