高拉速连铸机120mm小方坯结晶器的开发

Development of the Crystallize for the High-speed Continuous Casting Machine

介绍新近开发的120mm×120mm小方坯结晶器，它是在原1m／min低拉速结晶器基础上，参照某厂生产的120mm×120mm高拉速结晶器进行改进的。在高效连铸机上它连续拉钢的正常拉速为3m／min，最高可达3．7m／min，拉钢生产效率提高3—4倍。

This paper introduces a new crystallizer of the 120 mm × 120 mm small square billet based on the improvement of the low-speed crystallizer. The casting speed of the continuous casting machine can reach to 3 m/min, maximum speed 3.7 m/min. The production efficiency is raised 3 to 4 times.
