氧乙炔焰金属粉末喷涂技术是一项简便而有效的表面强化新技术,可用以提高金属部件的使用寿命。现将我厂对1200米~3高炉大钟拉杆、SPL-Z75型膨化机内套筒的喷涂工艺和糖厂压榨机底梳的喷涂工艺介绍如下。 1200~3米高炉大钟拉杆的喷涂修复某钢厂1200米~3高炉装料设备受到高压荒煤气的侵袭,大钟拉杆受到磨损,直径变细,泄漏严重,影响炉顶压力提高,影响生产。由于该厂仅有一台高炉,不宜停产更换新的大钟拉杆,为此进行了喷涂修复。
Oxyacetylene flame metal powder coating technology is a simple and effective surface hardening new technology can be used to improve the life of metal parts. Now I plant on the 1200 m ~ 3 blast furnace bell, SPL-Z75-type extruder within the sleeve of the spray process and the sugar mill at the end of the comb coating process described below. 1200 ~ 3 m blast furnace bell pull spray to repair a steel mills 1200 m ~ 3 blast furnace loading equipment was hit by high pressure gas shortage, the bell pull rod wear, diameter thinner, serious leakage, affecting the roof pressure increases, affecting the production . As the plant has only one blast furnace, should not stop production to replace the new bell pull rod, for which the spray repair.
