小型电弧炉除电极升降自动调节系统外,其余操作均以采用液压为宜。我厂按HGX-1.5型电炉图纸(由长春电炉厂提供)于73年自制了一台1.5吨的小型电炉。根据实际操作的要求,我们对油路进行了重新设计,几年来的运行表明,该系统简单可靠,安全方便。下面将该炉的油路和电路设计方案作一简略介绍。 设计油路,首先必须满足使用要求,做到“有的放矢”。因此应先根据电炉结构列出操作的具体要求:
In addition to small electric arc furnace lifting automatic adjustment system, the rest of the operation are to use hydraulic appropriate. I plant by HGX-1.5-type electric furnace drawings (provided by the Changchun Electric Furnace Factory) in 73 years made a small 1.5-ton electric stove. According to the actual operation requirements, we redesigned the oil circuit. The operation over the years shows that the system is simple, reliable and safe and convenient. Below the furnace circuit and circuit design for a brief introduction. Designing the oil circuit must first meet the requirements of use and achieve “targeted”. Therefore, the specific requirements of the operation should be listed according to the structure of the electric furnace:
