转炉挡火门传动装置设计

摘要：转炉炉前电动挡火大门其主要作用是转炉在炼钢生产时防止钢渣喷溅到转炉平台引起安全事故，保护炼钢工的安全，其次是改善炼钢作业时的作业环境。在转炉进行炼钢作业时必须将挡火门关上，在转炉进行加废钢、兑铁水时挡火门必须打开。挡火门的操作在转炉主控室，通过按钮起动驱动电机的正反转,实现挡火门的开启或关闭,该挡火门分左右两个门，可同时开动，也可单独开动，每扇门的开位，我们设置了电气限位和机械限位挡块。每个挡火门上方设置一个观察门，以便于炼钢时观察炉火，判断钢水的温度和出钢时间。观察门利用气动控制，在主控室操作。

Fire door driving device of converter design
Abstract: the converter furnace or electric fire door converter in steel-making production in its main role is to prevent accidents caused by spillage to converter steel slag platform, protect the safety of steel-making industry, followed by improving the working environment of steel-making operations. During the steelmaking in converter fire door must be closed, when presented in converter and scrap, hot metal fire doors must be open. Operations in converter main control room of the fire door, by button starting motor reverse, realization of opening or closing of fire doors, the fire doors left and right door, but at the start, can also be started separately, doors open, we have set a limit of electrical and mechanical limit stop. Observation on every fire door set above a door, so that when the steel-making observing fire, judge the temperature of the molten steel and steel time. Observation on the door with pneumatic control, in the main control room operations.
