现在反射炉熔炼的生产能力约占世界铜熔炼能力的60～70%。自反射炉诞生的第一天起就存在着的大缺点就是烟气中的SO_2不能经济地加以回收,污染大气。五十年代苏联研究热风旋涡熔炼时就曾打算利用旋涡熔炼改造反射炉。六十年代,我国曾进行过反射炉旋涡熔炼试验。氧气旋涡熔炼出现后,西德的KHD配以超声还原喷射熔炼技术作为改造反射炉的技术向世界技术市场推销,但未实现任何改造。 Reflective furnace smelting production capacity now accounts for about 60-70% of the world’s copper melting capacity. The big disadvantage that has existed since the first day of the self-reflection furnace is that the SO 2 in the flue gas can not be economically recovered and pollutes the atmosphere. In the 1950s, when the Soviet Union studied the hot-air vortex smelting, it intended to utilize the vortex melting to transform the reverberatory furnace. Sixties, China has conducted a reflection furnace vortex melting test. After the emergence of oxygen vortex smelting, West Germany KHD with ultrasonic reduction injection melting technology as a retrofit furnace technology to the world market, but did not achieve any transformation.
