应用喷镀修复辊颈,使用工具简单,操作容易,喷镀层可厚可薄,精加工也颇方便,是修复轧辊颈的最好方法.金属喷镀法,是将金属材料(大都是线材)自动地送入喷枪,它是利用可燃气和氧气的火焰使它熔化,再利用压缩空气将它喷成雾状,吹到毛糙的工件上,金属则附其上,形成金属薄层,通常喷镀的金属薄层,并不和基体材料发生焊合作用,也不起化合作用,只是相互嵌塞、钩结,工件表面事先弄得毛糙, Application of thermal spraying roll neck repair, the use of simple tools, easy to operate, the coating can be thick and thin, finishing is quite convenient, is the best way to repair the roll neck. Metal spraying method, is the metal material (mostly wire) Automatically into the gun, it is the use of flammable gas and oxygen to melt it, then use compressed air spray it into a mist, blowing rough workpiece, the metal is attached to the formation of thin metal layer, usually spray Plating a thin layer of metal does not occur with the base material welding, nor from the role of cooperation, but mutual impaction, hook knot, the workpiece surface made the rough beforehand,
