(一) 从建国开始至70年代初期20多年间,通过苏联技术援助建成鞍钢、本钢、武钢、包钢等一批高炉(容积为930～1513m~3),同时各冶金设计院、冶金机械厂和重型机械行业很快掌握了大中型高炉设备的设计和制造技术(除蒸汽透平鼓风机外),使我国高炉设备的技术水平很快达到世界50年代的先进水平。60年代以后,武钢、本钢和鞍钢进一步将高炉容积扩大至2000～2586m~3,随着炉顶操作压力和热风温度的提高,对炉顶装料和密封设备、热风炉结构、炉体冷却以及炉前机械等都作了一些改进。70年代初,开始
(1) From the founding of the People’s Republic of China to the early 1970s, a batch of blast furnaces (volume 930 ~ 1513m ~ 3) including Ansteel, Benxi Iron and Steel, WISCO and Baotou obtained technical assistance through the Soviet Union. At the same time, all metallurgical design institutes, metallurgical machinery The plant and heavy machinery industry quickly mastered the design and manufacturing of large and medium-sized blast furnace equipment (except for the steam turbine blowers), so that the technical level of blast furnace equipment in China reached the world’s advanced level in the 1950s. After the 1960s, WISCO, Bengang and Anshan Iron and Steel further expanded the blast furnace capacity to 2000 ~ 2586m ~ 3. With the increase of roof operating pressure and hot air temperature, the furnace top loading and sealing equipment, furnace structure, furnace cooling And before the furnace machinery made some improvements. The early 70s, the beginning
