摘　　要：厚板轧机机械压下制动装置为液压制动，使用一段时间后，液压制动装置经常漏油卸压，导致轧机在轧制力高的情况下辊缝变化甚至停机。为杜绝这种情况，通过对机械压下液压制动装置结构的分析，进行了国产化改进，达到了预期的效果。The breaker of heavy plate rolling mill adopts hydraulic break. After a period of time, leakage and pressure release often occurred on the hydraulic breaker, resulted in roll gap change under high rolling force, and even stop. In order to avoid these problems, analyze the structure of the hydraulic breaker of mechanical screw down, and make a localization improvement. After the improvement, the ex- pected results are achieved.
