工业电阻炉素有“电老虎”之称,热处理电炉用电量约为全国总发电量的0.8％,占机械制造行业用电量的27％。尤其是我国热处理设备普遍陈旧,浪费和不合理使用能源,还是相当普遍,因此开展以节能为中心的技术改造有很大潜力,也是根本措施。就全国而言,箱式电阻炉在热处理行业中量大面广,且原电阻炉保温性能差、升温慢、炉温不均匀、炉壳温度高、热效率低、能耗大。为此,全国都在开发新型高节能炉衬材料。江阴市耐火材料厂研制成功了HQ型绝热砖(无锡市地方标准)就是其中的一种,它采
Industrial resistance furnace known as “electric tiger,” said heat treatment electric furnace power consumption is about 0.8% of the country’s total generating capacity, accounting for 27% of the electricity used in the machinery manufacturing industry. In particular, China’s heat treatment equipment is generally obsolete, waste and unreasonable use of energy, or quite common, so to carry out energy-saving technological transformation center has great potential, but also fundamental measures. As far as the whole country is concerned, the box-type resistance furnace is widely used in the heat treatment industry. The original resistance furnace has poor thermal insulation properties, slow heating, uneven furnace temperature, high furnace temperature, low thermal efficiency and high energy consumption. To this end, the country is developing a new type of high energy-saving lining material. Jiangyin Refractory Factory successfully developed a HQ-type insulation brick (Wuxi local standards) is one of them, it mining
