结晶器是连续铸管机的心脏。由于其一边是冷却水,一边是高温铁水,工作条件恶劣,很易开裂,是连续铸管机的主要易损件。因此它的使用寿命是连续铸管工作者共同关心的。 六十年代一般用导热好、韧性好的低锡青铜,后因铜材缺乏,各厂先后采用铸铁结晶器。我厂在1966年也开始采用铸铁结晶器,但铸铁结晶器极易开裂, Mold is the heart of continuous casting machine. Because of its side is cooling water, while the high-temperature hot metal, poor working conditions, it is easy to crack, continuous casting machine is the main wearing parts. Therefore, its life is a common concern of continuous casting workers. Sixties with good thermal conductivity, good toughness, low tin bronze, after the lack of copper, the factory has adopted cast iron mold. I plant in 1966 also began to use cast iron mold, but very easy to crack cast iron mold,
