铁合金电炉的电极下放及铜瓦压紧装置是电炉设备的重要部分,目前除少数小电炉外,基本都用油压操作。今年4月,我厂5000KVA电炉采用全气压操作,运行七个月以来,情况良好。它比油压具有如下优点。①故障少气压系统压力小,不超过6公斤/厘米~2,比油压小几十倍,因而阀门、管路故障少。②结构简单油压抱闸靠油缸推动多块闸皮。油缸、连杆、闸皮、铰链组成复杂庞大的装置;而气动抱闸靠整个内胎充气来抱紧电极,结构小而简单,且不需要调整各闸皮。③安全、干净取消了油压系统,油起
Ferroalloy furnace electrode placement and copper tile pressing device is an important part of electric furnace equipment, with the exception of a few small electric furnace, the basic hydraulic operation. In April this year, our factory 5000KVA electric furnace with full pressure operation, running seven months, in good condition. It has the following advantages over hydraulic pressure. ① less pressure less pressure system pressure, not more than 6 kg / cm ~ 2, several times smaller than the oil pressure, so less valves, piping failure. ② simple structure of the hydraulic brake to promote multi-block brake shoe. The cylinder, the connecting rod, the brake shoe and the hinge form a complex and huge device. The pneumatic brake is inflated by the entire inner tube to tightly hold the electrode. The structure is small and simple, and the brake pads do not need to be adjusted. ③ safe, clean cancel the hydraulic system, oil from
