作者根据本厂的生产要求,为适应产品生产的需要,在对几种炉型进行比较的基础上,最后将冲天炉改为卡腰冲天炉。经实际使用,熔炼出了高温优质铁水,既解决了机床铸件的质量问题、降低了废品率,同时也减少了合金元素硅锰的烧损,取得了较好的经济效益。 According to our factory’s production requirements, in order to meet the needs of product production, based on the comparison of several types of furnaces, we finally changed the cupola to cardinal cupola. After the actual use, high temperature hot metal is melted, which not only solves the quality problems of machine tool castings, reduces the reject rate, but also reduces the burning loss of the alloying element silicomanganese and achieves better economic benefits.
