一、一般情况 电炉是机械、冶金、军工、轻纺等工业部门的重要工艺装备,在制造新材料,挖掘材料潜力,提高基础件和铸锻件质量等方面起着重要的作用。同时,电炉又是大量消耗电能的主要设备之一,目前全国电炉年耗电量约200亿度,约占全国发电量的7％,在所有用电设备耗电中仅次于交流电动机居为第二位。因此,研制节能型电炉,淘汰相应的老产品具有十分重要的意义。 电阻炉是电炉产品的一大类,主要用在热处理时加热金属零件,也有用作金属的熔化。我国生产电阻炉是解放后才开始的,绝大部分系仿苏产品,直到1972年我国电炉行业才采取全国统一设计的形式,对电阻炉进行整顿,整
First, the general situation Electric furnace is an important industrial and mechanical equipment, metallurgy, military industry, textile and other industrial equipment, in the manufacture of new materials, tap the potential of materials and improve the quality of the basic parts and castings and forging plays an important role. At the same time, the electric furnace is one of the major equipment consuming a large amount of electric energy. At present, the annual electric consumption of the electric furnace in the country is about 20 billion kWh, accounting for about 7% of the total generating capacity of the country, second only to the AC motor power consumption of all electric equipment second. Therefore, the development of energy-saving electric furnace, out of the corresponding old products is of great significance. Resistance furnace is a major category of electric furnace products, mainly used in the heat treatment of metal parts, but also for the melting of metals. China’s production of resistance furnace began after liberation, most of the imitation of su-products, until 1972, China’s electric furnace industry to take the form of a unified design, the resistance furnace for rectification, the whole
