目前,采用不同吨位的工频电炉来熔炼有色金属、黑色金属的单位日渐增多。济南汽总铸造厂通过合理的选配炉村材料来提高炉龄,总结出了成功的经验,使1.5T工频感应炉的炉龄达到363炉次,在同类熔炼设备中居领先水平。 炉衬材料 国内无芯感应电炉的炉衬.普遍采用以石英砂为主要材料打结的酸性炉衬。石英砂具有耐火度高(在1600℃内仍保持一定的机械性能)、体积变化系数小(在600℃以上耐急
At present, the use of different tonnage frequency electric furnace to smelt non-ferrous metals, black metal unit is increasing. Jinan Auto Foundry through reasonable selection of furnace materials to improve furnace age, summed up the successful experience so that 1.5T frequency induction furnace furnace to reach 363 heats, the same level of melting equipment in the lead. Furnace lining material Domestic coreless induction furnace lining. Commonly used quartz sand as the main material to tie the acid lining. Quartz sand with high refractoriness (at 1600 ℃ still maintain a certain mechanical properties), small volume change coefficient (more than 600 ℃ urgency
