摘要/Abstract

摘要： 研究了900~1200℃ 0~60 min微波加热和普通马弗炉加热两种方式,用固体脱碳剂碳酸钙(96.04%CaCO₃)对高碳铬铁粉(/%:55.79Cr，32.76Fe，8.16C，2.34Si)脱碳的影响。结果表明,试验条件下,微波加热高碳铬铁粉的固相脱碳效果较常规加热明显,而且常规加热时物料氧化程度严重,微波加热混合物料至1100℃ 60 min,铬铁粉脱碳率为79.04%,获得较好脱碳效果的同时,避免了物料的过分氧化。

关键词: 微波加热, 高碳铬铁粉, 固相脱碳效果, 氧化

Abstract: The effect of both method- microwave heating and conventional muffle furnace heating at 900 ~ 1200 ℃ for 0 ~60 min on high-carbon ferrochrome powder (/% : 55.79Cr, 32.76Fe, 8.16C, 2.34Si) decarburizing by solid decarburizer calcium carbonate (96.04% CaCO₃ ) has been studied. Results show that in test conditions the effectiveness of solid phase decarburization of high-carbon ferrochrome powder with microwave heating is more obvious than that with conventional heating and the oxidization of materials is serious as heating by conventional method. With microwave heating mixture at 1100 °C for 60 min the decarburization percentage of high-carbon ferrochrome powder is 79.04% to get better deearburization effectiveness and avoid excessive oxidation of materials.

Key words: Microwave Heating, High-Carbon Ferrochrome Powder, Solid Phase Decarburization Effectiveness, Oxidation
