为满足电力机车辅助电机注铝预热生产的需要,我厂设计、制造成功两台全纤维台车式箱形电阻加热炉。它的最大特点,是炉衬和电阻丝搁砖均采用硅酸铝耐火纤维材料,从而使加热炉轻型化。该加热炉的设计功率为72千瓦,最高工作温度为950℃,常用温度为800℃。生产运用表明,该炉具有升温快、保温好和节电显著的效果。加热炉的炉门升降、台车进出都采用电气控制,炉温可自动控制和手动控制,使用安全可靠。工作温度为800℃时,连续工作22小时后,炉壳外壁温度为50℃(平均值),说明加热炉的保温性能符合国家标准。
In order to meet the needs of electric locomotive auxiliary motor aluminum preheating, our factory designs and manufactures two full-fiber trolley-type box-type resistance furnaces successfully. Its most important feature is that the lining and the resistance wire resisting brick are made of aluminum silicate refractory fiber material, so that the heating furnace is light. The furnace design power of 72 kilowatts, the maximum operating temperature of 950 ℃, the common temperature of 800 ℃. Production and use shows that the stove has a fast warming, good insulation and energy-saving significant results. Heating furnace door lift, trolley out of the use of electrical control, the furnace temperature can be automatically controlled and manual control, the use of safe and reliable. Working temperature is 800 ℃, continuous working 22 hours, the shell wall temperature of 50 ℃ (average), indicating that the insulation properties of the furnace in line with national standards.
