本文简要阐述了连续铸造冶金基础及连续铸造过程的规律。在此基础上,对“真空上引连续铸造”所采用的容汉斯型结晶器的结构、工作原理、工作过程、换热特点等作了分析。并对生产铸造无氧铜杆的结晶器的基本结构及工艺参数提出了一些意见。根据试生产中一次偶然事故观察到的现象,对“真空上引连续铸造”现行结晶器提出了修改建议。
This article briefly describes the continuous casting metallurgical foundation and continuous casting process. On this basis, the structure, working principle, working process and heat exchange characteristics of the Rong Hans type crystallizer used in the continuous casting of vacuum are analyzed. Some suggestions on the basic structure and process parameters of the mold for producing oxygen-free copper rods were put forward. According to the phenomenon observed in a trial production, a suggestion of modification was made to the current mold with continuous casting in vacuum.
