摘　　要：为降低电耗,提高电炉生产能力,采用回转窑预热锰矿和热装工艺生产富锰渣用于冶炼金属锰和高碳 锰铁。此工艺可使产品电耗降低约20％,电炉生产能力提高20％以上。实践证明,回转窑在电炉富锰渣的生产中 的应用非常成功,经济效益显著。To reduce electricity consumption, the process of preheating manganese ore and hot charging in rotary kiln is to adopted to produce manganese-rich slag for smelting metal manganese and high carbon ferromanganese. The electricity consumption with the process can be decreased by 20% or so, production capacity can be increased over 20%. The practice shows that the application of manganese-rich slag production in rotary kiln is very successfully, the economic benefit is obviously.
