“XGH—1.5吨三相电弧炉的改进”一文在《铸造机械》1982年第二期上发表后,不少单位来信来访。现就有关问题,再谈我们对该电弧炉的改进。一、三相电极升降机构在熔炼过程中,电弧长度的调整由可控硅控制柜通过自动调节装置完成。该装置由直流电机、双级蜗轮减速器、钢丝绳卷轮、平衡重锤及定滑轮组成。原直流电机与减速器采用键用套筒硬性连接结构,键与套筒寿命较短,
After the article “Improvement of XGH-1.5T Three-phase Electric Arc Furnace” was published in the second issue of Foundry Machinery in 1982, many units wrote letters. Now on the issue, talk about our improvements to the electric arc furnace. First, the three-phase electrode lifting mechanism In the smelting process, the arc length adjustment by the SCR control cabinet through the automatic adjustment device to complete. The device consists of DC motor, two-stage worm reducer, wire rope reel, balance weight and fixed pulley composition. The original DC motor and reducer with a rigid sleeve with a key connection structure, key and sleeve life is shorter,
