为改善电极柄冷却问题,去年我厂在改造一台75kW侧埋式盐浴炉时,同时改进了电极柄的冷却装置(如图示)。在电极柄内钻两个互相平行的深孔,靠近深孔底部分别向上、向下钻与深孔相通的垂直孔,但不使两深孔直接相通。然后在电极外围焊上水套,冷却水由上孔进入,经水套进入下深孔 In order to improve the problem of electrode handle cooling, last year, when we renovated a 75kW side buried salt bath furnace, we also improved the cooling device of the electrode handle (as shown). Two deep parallel holes are drilled in the electrode shank. Vertical holes near the bottom of the deep hole are drilled upwards and downwards, respectively. However, the two deep holes are not directly communicated with each other. Then welding the water jacket on the periphery of the electrode, the cooling water enters from the upper hole and enters the lower hole through the water jacket
