The application and test of aqueous alkali cooking at 480?℃ comparing with that of KMnO 4 lye cleaning at 85?℃ show that KMnO 4 lye cleaning process is more practicable,but the concentration of KMnO 4 and NaOH need to be more than 80?g/L,the temperature of the solution is higher than 80?℃,the cleaning time is from 5?min to 10?min,which is 5?min shorter than that of aqueous alkali cooking.
不锈钢丝热处理后表面形成一层难以清除的氧化皮 ,4 80℃高温碱煮和 85℃高锰酸钾碱液的清洗对比试验和应用显示高锰酸钾碱洗工艺可行 ,但要求KMnO4 和NaOH浓度大于 80g L ,溶液温度高于 80℃ ,清洗时间5～ 10min ,比碱煮少 5min ;高锰酸钾碱液清洗效果好 ,不锈钢丝表面无黑色胶状物 ,而且不会产生过腐蚀 ,每吨不锈钢丝可节省电能 1875kW·h ,劳动环境也有很大改
