高速鋼工具經过氰化后,可以大大提高耐磨能力和使用寿命。目前一般工厂都是采用液体氰化法,但这种氰化法有很多缺点。例如刀具氰化后表面会生成黑点;氰化后需要經过中和、清洗和拋光等工序;液体氰化用的氰化盐有毒,而且价格高;等等。所有这些影响了氰化工艺的广泛采用。我厂工具分厂张安民同志最近試驗气体氰化获得初步成功。現在就把气体氰化的試驗經过介紹如下,供大家参考。 1.設备——我們是用带有馬弗鑵的Ц—60型爐来作試驗的;实际上,任何形式
After high-speed steel tools cyanide, can greatly improve the wear resistance and service life. The current general factory is liquid cyanide method, but this cyanide method has many shortcomings. For example, the surface of the tool cyanide will generate black spots; after cyanidation need to undergo neutralization, cleaning and polishing processes; liquid cyanide salt cyanide toxic, and the high price; and so on. All of these affect the widespread adoption of cyanidation processes. The initial success of the experimental gas cyanidation was recently achieved by Comrade Zhang Anmin, our factory tool branch. Now put the gas cyanide test described below, for your reference. 1. Equipment - We are experimenting with a Ц-60 furnace with a muffle tank; in fact, any form
