我厂二车间有四台固定式电炉,机械、电气装置和炉体等都是自己设计的。其中三台粗炼电炉,一台精炼电炉,机械设备都是相同的,电极都是φ600m/m 的自焙电极,电极把持器采用了钳链复合式结构,如图一所示。每根电极上装六块铜瓦。铜瓦与电极接触的电流密度:粗炼为δ=1.4A/cm~2;精炼为δ=0.9A/cm~2。铜瓦是通过吊杆吊在把持筒上的。这六块铜瓦是由三对(左、右)铜瓦组成,经三个销子和三个螺栓间隔相连起来。三个销子插在左、右的铜瓦间,使两铜瓦形成铰链。三根螺栓相切于电极的断
I plant two workshops have four fixed-type electric furnace, machinery, electrical installations and furnaces are all their own design. One of the three smelting furnace, a refining furnace, machinery and equipment are the same, the electrodes are φ600m / m self baking electrode, the electrode holder using a clamp chain composite structure, as shown in Figure 1. Each electrode is loaded with six copper tiles. The current density of the contact between the copper tile and the electrode is: δ = 1.4A / cm ~ 2 for crude; δ = 0.9A / cm ~ 2. Copper tile is hanging on the control tube through the boom. The six tiles are made of three pairs (left and right) of copper tiles, connected by three pins and three bolts spaced apart. Three pins inserted in the left and right of the copper tile between the two tiles to form a hinge. Three bolts tangent to the electrode off
