一、概述 目前,精密合金生产由冶炼直至冷轧成薄带成品,一般都必须经过热轧开坯工序。而在热轧开坯过程中,较多的冶金单位,常采用(?)燃油气连续炉加热毛坯的方法。这种加热方法尽管简便、适用于大生产,但是也伴随着一些难以克服的弊病,由于合金毛坯于高温下和空气中的氧剧烈地相互作用,表面上便很快形成一层氧化皮膜,有时,一些温度波动范围大的加热炉,极易使毛坯严重氧化,金属表面往往会剥落厚厚一层皮膜,此即谓之合金的烧损。有文章报导这种金 I. Overview At present, the production of precision alloys from smelting until cold rolled into finished products, generally have to go through the hot-rolled billet process. In the hot-rolled billet process, more metallurgical units, often using (?) Continuous furnace fuel oil heating blank. Although this method of heating is simple and suitable for large-scale production, it is accompanied by some insurmountable problems. Since the alloy blank strongly interacts with the oxygen in the air at high temperature, an oxide film is rapidly formed on the surface and sometimes , Some furnace temperature fluctuations in a large area, easily rough serious oxidation, the metal surface often peel off a thick layer of film, which is called the burning of the alloy.
