1987年3月8～11日,冶金部在鞍钢召开了高炉用氮化硅结合碳化硅砖技术成果鉴定和推广应用会,除参加研究、生产、应用的北京钢铁研究总院、山东八三厂和鞍钢外,还邀请了各大型钢铁企业、部属设计院及有关钢铁、耐火材料研究院所和碳化硅生产厂家等36个单位共130余人参加。到会代表对北京钢铁研究总院、山东八三厂和鞍钢三家密切结合,成功地研制出了可行的碳化硅砖生产工艺及其产品理化性能达到国外同类产品(refrax-20)的水平给予充分肯定。鞍钢6号高炉应用氮化硅结合
March 8, 1987 to March 11, the Ministry of Metallurgical held in Anshan Iron and Steel Co., Ltd. blast furnace with silicon carbide bonded silicon carbide technology identification and promotion of the application will be, in addition to participate in the research, production and application of Beijing Iron and Steel Research Institute, Shandong 83 plants And Anshan Iron and Steel, but also invited a large iron and steel enterprises, subordinate design institute and the relevant steel, refractory research institutes and silicon carbide manufacturers 36 units a total of more than 130 people attended. The delegates to the Beijing Iron and Steel Research Institute, Shandong Baishan plant and Anshan Iron and Steel three closely integrated, successfully developed a feasible production process of silicon carbide bricks and their physical and chemical properties to achieve the level of foreign similar products (refrax-20) to give full sure. Anshan Iron and Steel No. 6 blast furnace application of silicon nitride
