4 热喷涂技术在钢铁工业中的应用 在钢铁加工过程中,需要大量经过表面处理的辊类件,它们的好坏直接影响到产品的质量。这些辊类件在使用过程中主要存在以下问题。 炉内辊与高达1100℃炉内气氛发生化学反应,并产生严重粘着磨损和磨粒磨损。还有一个主要问题就是在辊子表面上产生熔渣和氧化物结瘤,影响产品的表面质量。 4 thermal spray technology in the steel industry in the steel processing, the need for a large number of surface treatment of the roller parts, their quality directly affects the quality of the product. These roller parts in the course of the main problems the following. The furnace rolls chemically react with the furnace atmosphere up to 1100 ° C and cause severe adhesion wear and abrasive wear. A further major problem is the formation of clinker and oxide nodules on the surface of the roll, affecting the surface quality of the product.
