本文介绍了硅热法炼镁还原炉真空管路与设备的配备。针对具有１６个还原罐的横罐还原炉的真空管道设计，计算管道直径为８０ｍｍ，长为１０００ｍｍ，真空管道的气导率为９３．２１／ｓ。真空设备的匹配为一台还原炉配２ＳＫ－６水环泵一台，每四个还原罐与一组真空机组相联接，按还原罐内径Φ２６０ｍｍ计算，Ｈ滑阀泵为Ｈ－７０１／ｓ，ＺＪ罗茨泵为ＺＪ－６００１／ｓ。一台还原炉匹配５组真空机组即可满足生产要求，在４５分钟内可使真空系统统从常压至剩余压力达１３Ｐａ以内。
This article describes the silicon thermal refining magnesium reduction furnace vacuum piping and equipment. For the design of the vacuum pipe of the horizontal reduction furnace with 16 reduction tanks, the pipe diameter is calculated to be 80 mm and the length to be 1000 mm, and the air conductance of the vacuum pipe is 93.21 / s. The matching of the vacuum equipment is a reduction furnace equipped with a 2SK-6 water ring pump. Each four reduction tank is connected with a vacuum unit. According to the reduction tank inner diameter Φ260mm, the H slide valve pump is H-701 / s, ZJ Roots pump ZJ-6001 / s. A reduction furnace matching 5 sets of vacuum units to meet production requirements in 45 minutes to make the vacuum system from the atmospheric pressure to the remaining pressure of 13Pa or less.
