摘要
板坯连铸是炼钢生产的重要环节,生产工艺比较复杂,受生产工艺和设备因素影响,容易发生黏结漏钢.为有效避免黏结漏钢事故发生,应结合现场具体情况,从保护渣选取、结晶器液面波动的控制、水口插入深度的制定、拉矫速度变化以及捞渣操作工艺执行等方面认真研究分析,并采取相应措施,最大限度降低黏结漏钢事故的发生机率,全面提升板坯连铸生产效率和产品质量.
Abstract
Continuous casting of slab is an important part of steelmaking production,and the production process is relatively complex.Due to the influence of production process and equipment factors,it is easy to cause bonding and steel leakage.To effectively avoid the occurrence of adhesive steel leakage accidents,it is necessary to carefully study and analyze the selection of protective slag,control of crystallizer liquid level fluctuations,formulation of nozzle insertion depth,changes in pulling and straightening speed,and execution of slag removal operation process based on the specific situation on site.Corresponding measures should be taken to minimize the probability of adhesive steel leakage accidents and comprehensively improve the production efficiency and product quality of slab continuous casting.
