有芯工频感应炉具有加热快、生产率高、金属烧损少、操作方便、劳动条件好等优点,因此被广泛地用作有色金属铸造的熔炼设备。在铁路系统的铸铜生产中,各企业基本上都采用同一设计的容量为500公斤的有芯工频感应炉。我厂在使用该设备的过程中,有如下两个问题,有待解决。 1.由于生产规模和用电紧张等原因限制,采取每周集中开炉2～3天的办法安排生产。在冷炉加热熔沟起熔体时,经常发生熔沟起熔
Core frequency induction furnace with heating fast, high productivity, less metal burning, easy operation, good working conditions, etc., it is widely used as a non-ferrous metal casting smelting equipment. In the copper production of the railway system, all enterprises basically adopt the same design core capacity induction furnace with a capacity of 500 kg. I plant in the process of using the device, the following two problems to be solved. 1. Due to restrictions on the scale of production and electricity shortage, take a weekly centralized open 2 to 3 days to arrange production. Melting in the cold melting furnace from the melt, the melt often occurs melting ditch
