真空自耗电弧炉防爆设计与安全生产研究

真空自耗电弧炉是钛及钛合金制备的主要设备,但在熔炼过程中存在严重的爆炸风险。该文对钛及钛合金真空自耗熔炼爆炸机理进行研究,简要分析引发爆炸的几种情况,通过对爆炸威力的计算,研究包括水冷结晶器、真空熔炼室、X-Y调节机构等在内的设备主体方面,以及包括防爆墙、泄爆口和防爆门等在内的设备基础方面的防爆设计,在操作系统中设置防爆预警,并针对防范重点提出相应的安全生产建议措施,避免熔炼爆炸事故的发生。

Vacuum consumable arc furnace is the main equipment for the preparation of titanium and titanium alloys,but there is a serious risk of explosion in the melting process.In this paper,the explosion mechanism of titanium and titanium alloy vacuum consumable melting is studied,and several situations causing the explosion are briefly analyzed.Through the calculation of explosion power,this paper studies the explosion-proof design of the main body of equipment,including water-cooled mould,vacuum melting chamber,X-Y regulating mechanism,as well as explosion-proof design of equipment foundation,including explosion-proof wall,explosion vent and explosion-proof door,etc.,and sets explosion-proof early warning in the operating system.According to the key points of prevention,the corresponding safety production suggestions and measures are put forward to avoid the occurrence of smelting explosion.
