日本住友金属工业公司新投产一台六流圆坯连铸机。这台连铸机投产标志着住友公司和歌山厂正在分三期进行的现代化改造计划中的第一期已告结束(其它两期工程包括建设一套无缝管轧机机组及一个转炉炼钢车间)。这个现代化改造工程共投资1300亿日元,预计将于1999年7月完成。新投产的圆坯连铸机的设计能力为100万吨/年;曲率半径10.5米,4点矫直;结晶器内配备有电磁搅拌器,结晶器液面高度由涡流传感器监测,并由滑动水口控制;滑动水口由步进液压缸驱动,由机器人进行更换;铸坯在37m处受到轻压下作用以减少中心疏松,进而
Sumitomo Metal Industries Co., Ltd. put into operation a new round six round billet caster. The first phase of modernization of the Sumitomo Wakayama plant, which is underway in phases, has come to an end (the other two phases include the construction of a seamless tube mill and a converter steelmaking plant) . This modernization project invested a total of 130 billion yen and is expected to be completed in July 1999. New round billet caster design capacity of 1 million tons / year; radius of curvature of 10.5 meters, 4 straightening; mold equipped with a magnetic stirrer, mold height by the eddy current sensor monitoring, and by sliding Nozzle control; sliding nozzle driven by a stepper hydraulic cylinder, replaced by a robot; slab at 37m by light pressure to reduce the role of loose center, and thus
