1983年3月15～17日由冶金部科技司主持在鞍钢召开了高温内燃式热风炉技术鉴定会。鉴定内容包括高温内燃式热风炉、高风温热风阀、热风炉并联送风风温自动控制等三项研究成果。自1974年以来该公司已陆续完成上述项目的试验研究和工业应用考核工作。其中9~#高炉高温内燃式热风炉在国内首次综合使用了锥形拱顶、复合式火井隔墙、七孔高效格子砖、带予混装置的陶瓷燃烧器等新技术装备,经高风温试验,风温可达1200℃以上,热效率高,设备状况良好。经改造后的GRF—11B型热风阀,采用了全焊接的新式结构,热损失小,开关灵活,寿
1983 March 15 to 17 by the Department of Metallurgical Science and Technology held in Anshan Iron and Steel High-temperature internal combustion stove technology appraisal. Identification includes high temperature internal combustion hot stove, high temperature hot air valve, hot air stove in parallel with air temperature control of three research results. Since 1974, the company has successively completed the pilot research and industrial application assessment of the above projects. Among them, the 9 ~ # blast furnace high-temperature internal combustion hot-blast stove integrates the new technology and equipment such as conical dome, compound fire shaft wall, seven-hole high-efficiency grid brick, and ceramic burner with premixing equipment for the first time in China. Temperature test, the wind temperature up to 1200 ℃, high thermal efficiency, equipment in good condition. After the transformation of the GRF-11B hot air valve, the use of all-welded new structure, heat loss, flexible switch, life
