长期以来困扰钢铁企业连铸生产 ,导致出钢量低、拉速慢、钢坯质量不稳定的一道难题 ,近日得到解决。由北京中色机电设备有限公司开发研制的中、窄带坯管式结晶器经数家企业试用 ,取得成功。与老式组合式结晶器相比 ,过钢拉速增长 30 %,设备成本投资下降 30 %。目前 ,这项技术已 For a long time troubling the iron and steel enterprises continuous casting production, resulting in a low amount of steel, slow speed, the instability of the quality of the billet has recently been solved. Developed by Beijing Zhongse Electromechanical Equipment Co., Ltd., medium and narrow-band pre-mold crystallizers have been successfully tested by several enterprises. Compared with the old-fashioned modular crystallizer, the steel pulling speed increased by 30%, equipment cost investment decreased by 30%. At present, this technology has been
