漏炉事故是感应熔炼(或保温)炉运行中危害很大的事故之一。发生此类事故不仅减少生产时间,而且有时毁坏设备甚至发生人员伤亡。因此预测漏炉、防止漏炉历来得到电炉设计者及操作运行工作者的重视。对无心感应熔炼(或保温)炉,为了实现漏炉报警,在炉体打结炉衬时放入一不锈钢护套或铜网护套。将炉内熔化金属和护套接入一安全电源(如36V),一旦发生漏炉事故,该电源接通,发出声光信号报警。但当发生金属液的收敛性渗漏事故时,任何局部的金属液与保护套或保护网的短接都发生报警信号,而
Leakage furnace accident induction melting (or insulation) furnace operation is one of the most hazardous accidents. Occurrence of such accidents not only reduce production time, and sometimes destroy equipment or even casualties. Therefore, it is predicted that the leak furnace will prevent the leakage furnace from getting the attention of electric furnace designers and operators. Unintentional melting smelting (or insulation) furnace, in order to achieve the leak furnace alarm, when the furnace body knot lining into a stainless steel sheath or copper mesh sheath. The molten metal and the furnace access to a safe power supply (such as 36V), in the event of a leak furnace accident, the power connected to the sound and light signals alarm. However, in the event of a convergent leakage of liquid metal, an alarm signal will be generated from any localized liquid metal and the shorting of the protective sheath or protective net
