目前国内解决水平连续铸锭“跑火”问题的方法主要是采用闸阀法。其原理是在炉膛内安装或筑砌流槽,流槽出口中部上方加一闸阀,闸阀与闸杆相连,当出现“跑火”(即金属液从结晶器的石墨模溢出)后,利用人工旋转螺旋机构或采用杠杆机构使闸杆下降以堵塞流槽。其特点是操作简单,使用方便,易于控制,但速度慢,安全性差,再者闸杆是由高
At present, the domestic solution to the level of continuous ingot “running fire” problem is mainly the gate valve method. The principle is to install or build a flow channel in the furnace, and a gate valve is installed above the central part of the outlet of the flow channel. The gate valve is connected with the brake rod. When a “running fire” (that is, metal liquid overflows from the graphite mold of the mold) Rotate the screw mechanism or use a lever mechanism to lower the brake lever to block the runner. It is characterized by simple operation, easy to use, easy to control, but slow, poor security, and then by the high bar
