我厂铝电解用400×400×1100预焙阳极,系用2500吨卧式水压机挤压成型,在敞开式环式炉内焙烧而成。采用的原料有10～20％沥青焦(或焦化焦)90～80％3号延迟焦。近年来曾用镇江焦化焦70～80％与沥青焦配成混合焦(焦化焦是用3号延迟焦焦化而成)。预焙阳极的配方:79±2％混合焦;21± I plant aluminum electrolysis 400 × 400 × 1100 prebaked anodes, with 2500 tons of horizontal hydraulic press extrusion molding, open-loop furnace roasting. Raw materials used 10 to 20% of the pitch coke (or coking coke) 90 ~ 80% 3 delay coke. In recent years, 70 ~ 80% of the coking coke in Zhenjiang has been mixed with the coke of the coke (coking coke is made with the delayed coking of No. 3). Pre-baked anode formulation: 79 ± 2% mixed coke; 21 ±
