液压带电自动压放电极,在国内外大中型电炉上早已采用,但应用于小型铁合金电炉,尚未见到文献介绍。我厂在1983年恢复重建306号炉(容量1800～2400kVA)时,将液压带电自动压放电极技术成功地移植到小型铁合金电炉上,经过两年的生产考验,运行可靠,达到了预期的目的。在小型铁合金电炉上应用液压装置,有一定的难度,特别是电极把持器部分,由于炉子容量小,各方面尺寸受到限制。要在小尺寸范围内实现电极的液压压放,设计时就要全面考虑、周密分析才能实现。我们在3M 平台(操作平台)采用矮烟罩炉盖,使液压装置部分避免高温辐射,从而保证了液压 Hydraulic automatic voltage discharge electrode, at home and abroad have long been used in large and medium-sized electric furnace, but used in small ferroalloy furnace, has not yet seen the literature. When the plant was restored and rebuilt in 1983 (capacity: 1800 ~ 2400kVA), our plant successfully transplanted the hydraulically charged automatic voltage discharge electrode technology into a small ferroalloy electric furnace. After two years of production test and reliable operation, it achieved the expected purpose . In the small ferroalloy furnace application of hydraulic devices, a certain degree of difficulty, especially the electrode holder part, due to the small furnace capacity, all dimensions are limited. In the small size of the electrode to achieve the hydraulic pressure, the design should be fully considered, careful analysis can be achieved. We use the 3M platform (operating platform) hood hood, the hydraulic part of the high-temperature radiation to avoid, thus ensuring the hydraulic
