摘　　要：影响横向拉裂缺陷的主要因素有合金特性、铸造工艺参数和结晶器设计及其结构、铸造操作等。通过调整控制熔体温度、一次冷却强度、铸造速度等铸造工艺参数,合理设计结晶器,定期维护结晶器和正确的铸造操作,可以防止横向拉裂缺陷的产生。The main factors affect transverse cracking defect are alloy characteristics casting process parameters and mold design and its structure, casting operation,etc.. The transverse cracking can be voided by aid of adjusting casting process parameters such as, controlling the temperature of melt, primary cooling, casting rate, etc. designing mold reasonably, periodic maintenance of mold and correct casting operation.
