摘要
用无氧化预热炉森吉米尔法进行钢带连续热镀铝的半工业试验,探索各种工艺条件,找出了最佳的热镀铝工艺参数,并镀出质量和性能符合ISO-5000的镀铝钢带。镀层的微观组织均匀,合金层由FeAi_2Si的金属间化合物构成。经800℃100h氧化后,镀层表面的铝浓度仍然很高,这表明镀层具有好的抗氧化性,
Semi-industrial experiments of hot-dip aluminizing of steel strip were carried out using non-oxidizing preheating furnace of semdzimir continuous line. Through exploration of the technology conditions optimal parameters for the aluminizing were found. Under these conditions the qualities and properties which conform to the ISO-5000 of aluminizing steel strip can be obtained. The microstruture of aluminized layer, which consists of FeAl_2Si, was well distributed. After 800℃×100 hr oxidation tests, content of the aluminium in the coating layer still remains high. The coating exhibits a high oxidation resistance.
