铝在钢中主要是以金属固熔体状态存在,少部分以氧化铝(AI_2O_3)和氮化铝(AIN)形式存在。一般认为金属铝和氮化铝可溶于酸,所以称之为酸溶铝;氧化铝一般不溶于酸,所以称之为酸不溶铝。酸不溶铝在钢中的含量远远小于酸溶铝。酸溶铝和酸不溶铝只是在特定的分析条件下给予的区分。我厂电炉车间冶炼的OCr18Ni11Ti等钢在电渣重熔后需作残铝分析。由于钢种成分比较复杂,含铝又比较低,所以一直不能提供准确可靠的分析数据。为了解
Aluminum is mainly present as a solid metal in the steel, and a small portion is in the form of aluminum oxide (AI_2O_3) and aluminum nitride (AIN). Metallic aluminum and aluminum nitride are generally considered soluble in acid, so called acid-soluble aluminum; alumina is generally insoluble in acid, so called acid insoluble aluminum. Insoluble aluminum content in the steel is far less than acid-soluble aluminum. Acid-soluble aluminum and acid-insoluble aluminum are only differentiations given under specific analytical conditions. The OCr18Ni11Ti steel, which is smelted in the electric furnace workshop in our factory, needs to be analyzed for residual aluminum after ESR. Due to the complexity of steel composition, aluminum is relatively low, it has been unable to provide accurate and reliable analytical data. To understand
