在毛主席关于“独立自主、自力更生”方针指引下,我们采用土法上马,经过反复实践,研制成功简易箱形保护气体电炉,已于一九六九年投产使用。这台电炉的加热炉是由一般的箱形电炉(RJX-45-9)增加进气管道改装而成;其发生炉是采用乙醇加水为原料的吸热式保护气体。这台设备的优点是:投资少、上马快,维修方便,特别是选用本地区资源丰富的乙醇为发生炉原料,从而保证了正常使用。
Guided by Chairman Mao’s principle of “independence and self-reliance,” we launched the simple box-shaped protective gas electric furnace with the introduction of the indigenous method through repeated practice and put it into operation in 1969. This electric furnace heating furnace is a general box-shaped electric furnace (RJX-45-9) to increase the intake pipe converted; the furnace is the use of ethanol and water as the endothermic shielding gas. The advantages of this equipment are: less investment, quick start, easy maintenance, especially the selection of the region’s resource-rich ethanol for the furnace raw materials, thus ensuring the normal use.
