本文介绍了高炉铁水直接生产各种铸铁件的情况,以及在应用中尚存在的主要问题,从而说明了直接利用高炉铁水生产铸件是钢铁企业一种节能的有效途径,值得大力推广应用。引言直接利用高炉铁水浇注铸件,国外早在三十年代就开始采用,直接浇铸与冲天炉铁水浇铸相比,具有节能、铸件寿命长等优点,因此各工业发达国家发展较快。我国钢铁厂家在六十年代中期试验过。目前,很多钢铁厂家已陆续采用这种方法生产铸件。
This paper introduces the direct production of various cast iron parts by blast furnace hot metal and the main problems that exist in the application. This shows that the direct use of blast furnace hot metal to produce castings is an effective way for steel enterprises to save energy and is worth popularizing. Introduction The direct use of blast furnace hot metal pouring castings, foreign as early as the thirties began to adopt, direct casting and hot cupola casting compared with energy saving, long casting life, so the rapid development of industrialized countries. China’s steel manufacturers in the mid-60’s tested. At present, many steel manufacturers have been using this method to produce castings.
