摘要
通过改进连铸小方坯引锭燕尾槽连接件的加工工艺,实现一次冷墩成型,减少应力脆点。同时优化连接件材质,提高抗交变应力强度。有效解决了连接件在使用过程中断裂问题。提高钢坯成才率和生产效率,降低了工人劳动强度。
Through improving the processing technology of the dummy dovetail groove fittings used in small billet continuous caster,a cold pier molding is achieved,stress brittle point is reduced. Meanwhile,fitting material is optimized,the stress strength is improved. It effectively solves the fitting fracture problems in using process. Thus the success rate of the billet and the production efficiency are promoted while the labor intensity of workers is reduced.
