英国 Brgan donkin 公司提出了一种钢液真空处理装置(见附图)。钢液从钢包流到真空室2上面的中间包1内,然后经水口3流到易熔片4上,易熔片熔化后,金属即流到真空室中由煤气烧嘴5预热好的浇包6内。这样钢液在流注状态下进行了第一次除气。当钢液充满浇包6后即将它倾转,使钢 British Brgan donkin company proposed a molten steel vacuum processing device (see attached). Molten steel flows from the ladle to the tundish 1 above the vacuum chamber 2 and then to the fusible sheet 4 through the nozzle 3. After the fusible sheet melts, the metal flows to the vacuum chamber to be preheated by the gas burner 5 Ladle 6 inside. This molten steel in the state of the first degassing. When the molten steel filled ladle 6 is about to tilt it, so that steel
