根据除鳞介质的不同可将除鳞工艺分为高压水除鳞、压缩气体除鳞、喷沙除鳞。其中高压水除鳞是国内外非常成熟也是运用非常广泛的技术,在国内的型钢生产工艺中,基本上全部采用高压水除鳞。气体除鳞和喷沙除鳞在国外是比较成熟的技术,在实际生产中也得到广泛运用。国内对于气体除鳞和喷沙除鳞尚处于摸索研究阶段,本文主要针对气体除鳞工艺技术原理进行简单介绍。
According to the descaling medium can be divided into different descaling high-pressure water descaling, compressed gas descaling, sandblasting descaling. One of the high-pressure water descaling is very mature at home and abroad is the use of a very wide range of technologies in the domestic steel production process, basically all the high-pressure water descaling. Gas descaling and sandblasting descaling in foreign countries is more mature technology, has also been widely used in actual production. For the domestic gas descaling and sandblasting descaling is still in the groping phase of research, this paper mainly for gas descaling technology principle briefly.
