我国炼钢生产技术的发展

TECHNOLOGICAL ADVANCE IN STEELMAKING IN CHINA

本文叙述了我国1992年炼钢生产的技术进步和取得的成绩,全国年产钢8000万t,重点企业连铸比达到31.94％,地方企业连铸比达到32.12％,品种和质量有了较大提高。还总结了我国炼钢生产在转炉、电炉、平炉和相关技术上的开发和展望,今后的重点工作应放在品种、质量、节能和降耗等方面。

Technological advance and achievements in the country's steelmaking sector in 1992 are retro- spected in the paper. Annual steel output of the country scored 80 million tons and the continuous casting ratios attained 31.94% for the country's key steelmaking enterprises and 32.12% for the lo- cal steelmakers this year. Both product varities and quality had been drastically improved by the year. Development of steelmaking technologies in converter, electric arc furnace, open hearth and relevant techniques are summerized and prospected. It's concluded that emphasis shall be placed upon product variety, quality, energy saving and consumption reduction in the iron and steel industry in the fu- ture.
