为了提高产品质量、增加品种,我厂試驗成功用火法冶炼生产零号锑。生产方法是将赫氏炉挥发焙烧得到的锑氧预先煅烧,然后进行还原熔炼。煅烧锑氧是在平底隔焰反射炉进行的。煅烧的目的在于除去大量的砷和硒。煅烧过程采用如下技术条件:煅烧温度530～550℃,料层厚度42～45毫米,煅烧时間90～100分钟,耙动
In order to improve product quality and increase variety, our factory successfully produced zero antimony with pyrometallurgy. The production method is that the antimony oxygen obtained by volatilization and roasting in a furnace of Hertzian is pre-calcined and then reduced and melted. Calcined antimony oxygen is carried out in a flat bottom flame reverberatory furnace. The purpose of calcination is to remove large amounts of arsenic and selenium. Calcination process using the following technical conditions: calcination temperature 530 ~ 550 ℃, material thickness 42 ~ 45 mm, calcination time 90 ~ 100 minutes, rake
