在鼓风炉炼铜工艺中,前床的结构及前床容积的合理选择,对于冶炼的技术经济指标有直接的影响。 1965年前,第一冶炼厂的鼓风炉前床容积为45米~3;1965年将前床改建为60米~3。随着生产的发展,鼓风炉扩大为10.5米~2,粗铜年产量比1965年前增长了60％,但前床容积仍是60米~3。几年来的生产实践表明,将前床扩大到60米~3,对改善冶炼的技术经 In blast furnace copper refining process, the structure of the front bed and the reasonable choice of the volume of the front bed have a direct impact on the technical and economic indicators of smelting. Before 1965, the first smelter blast furnace bed volume of 45 meters to 3; in 1965 the former bed converted to 60 meters ~ 3. With the development of production, the blast furnace expanded to 10.5m ~ 2. The annual output of blister copper increased by 60% compared with that before 1965, but the volume of the front bed was still 60m ~ 3. Years of production practice shows that the bed will be expanded to 60 m ~ 3, to improve the smelting technology
