摘　　要：目前我国原镁生产均采用皮江法工艺,存在能源消耗高、资源利用效率低、环境污染严重及碳排放强度高的问题。本文分析了镁冶炼行业碳排放现状,从煅烧炉、还原炉和炼镁新技术3个方面阐述了镁冶炼节能减排的技术和方法。研究表明推动采用HTAC技术、富氧燃烧技术等加热方式的新型煅烧炉及采用微波、感应、等离子加热还原炉等新装备的发展与应用,开发短流程绿色炼镁技术、连续冶炼技术、铝热法炼镁技术等高效节能减碳新技术,是实现镁行业碳中和目标及可持续发展的有效途径。At present, Pidgeon process is used in magnesium production, which has high energy consumption, low resource utilization efficiency, serious environmental pollution and high carbon emission intensity. This paper analyzed the carbon emission status of magnesium smelting industry, and pointed out the ways of energy saving and emission reduction in magnesium smelting under the background of carbon neutralization from three aspects: calcining furnace, reduction furnace and new magnesium smelting technology. This paper promotes the development and application of new calcining furnace using heating ways of HTAC technology, oxygen-enriched combustion technology, etc., microwave, induction, plasma heating reduction furnaces and other new equipment, and develops new technologies with high efficiency, energy saving and carbon reduction, such as short-process green magnesium smelting technology, continuous smelting technology and alumino-thermic magnesium smelting technology, so as to finally achieve the goal of carbon neutrality and sustainable development of magnesium industry.
