节能环保型连铸机二冷室蒸汽排放装置及方法
本专利技术涉及冶金炼钢连铸领域,特别是涉及一种节能环保型连铸机二冷室蒸汽排放装置及方法。
技术介绍
连续铸钢过程是把高温钢水连续不断地浇铸成具有一定断面形状和一定尺寸规格铸坯的生产工艺过程,完成此过程需要连铸成套设备完成,浇钢设备、连铸机本体设备、切割区域设备、输送设备等构成了连续铸钢核心设备,一般成为连铸机。其中,连铸机二冷室内的水蒸汽是在中间包钢液注入结晶器后,表面只能结成一层较薄的坯壳,出结晶器后,必须经过二次冷却水喷淋,才能逐渐形成铸坯。当经过连铸机二冷室时,由于二次冷却水的喷淋而产生大量的水蒸汽,为把二冷室内的水蒸汽排到车间厂房外,在二次冷却区设置一套排二冷蒸汽管道。目前冶金连铸生产中,二冷室内的水蒸汽排到车间厂房外,多采用大功率电机直接驱动风机的排出模式,用电量能耗大、安装要求高、维护成本高等问题。
