长期以来,国内冲天炉化铁采用冶金焦。铸造行业多年呼吁,要求生产和供应铸造焦,以提高铁水及铸件质量,降低能耗和减少废品损失。从1981年7月冶金部及原一机、农机三部联合召开铸造焦座谈会以来,此项工作得到国家计委、经委及各兄弟部的支持,一些单位也先后开展了铸造焦的研制工 For a long time, the domestic cupola iron used metallurgical coke. The foundry industry has for many years called for the production and supply of foundry coke to improve the quality of molten iron and castings, reduce energy consumption and reduce waste loss. Since July 1981, the Ministry of Metallurgy, the original machine, and the Agricultural Machinery Department jointly held the foundry coke workshop. Since the work was supported by the State Development Planning Commission, the Economic Commission and the Brothers, some units have also started the research and development of foundry coke.
