冶金部于1986年3月11日在湖北省宜昌市召开了铸锭技术调工作会议。会上总结了“六五”期间浇注工艺的发展和有关技术问题,讨论了1986年使镇静钢成坯年达到87％,沸腾钢达到94.5％以及进一步改善钢锭质量和提高钢液收得率的措施。目前全国模注钢仍占很大的比重(88％),所以提高模注技术仍是我国冶金工业发展的重要措施。1985年全国重点企业基本上实施了绝热板,保护渣、防缩孔剂浇片等技术,成坯率年达到85％。地方企业使用绝热板浇注逐年增加,成坯率达89％。模注沸腾钢成坯率达到了93％,“七五”期间模注技术新工艺新方法将得到进一步开发研究与推广应用。
Ministry of Metallurgical in March 11, 1986 in Yichang City, Hubei Province, held a casting technology transfer conference. At the meeting, the development of casting technology and related technical problems during the “Sixth Five-Year Plan” period were summarized. In 1986, the billet age of the stabilized steel reached 87%, the boiling steel reached 94.5% and the quality of steel ingot further improved, and the yield of molten steel was also discussed Measures. At present, the country still accounts for a large proportion of injection molding steel (88%), so improving the injection molding technology is still an important measure for the development of China’s metallurgical industry. In 1985, key enterprises in China basically implemented such technologies as thermal insulation panels, mold flux and shrink-proofing agent pouring tablets. The rate of forming billet reached 85% in 1985. Local enterprises use insulation panels pouring increased year by year, into the billet rate of 89%. Injection molding billet steel billet reached 93%, “75” during the new technology injection molding method new method will be further developed, research and promotion.
