干熄焦用钢丝绳由于受气体侵蚀、粉尘黏附、红焦烘烤等原因,恶劣的工作环境对钢丝绳的综合性能要求很高。介绍6×K36WS+IWRC—30干熄焦用压实股钢丝绳试制过程,给出干熄焦提升用钢丝绳生产技术要求。选用直径8.0 mm SWRH77A盘条作为制绳钢丝原料,针对不同层成品钢丝直径选择的半成品钢丝直径分别为3.40,4.30,5.30,6.50 mm。拉丝采用多道次、小压缩率方法,股绳生产中采用股淋油,钢丝绳表面涂进口油脂,股绳捻距79.2～83.3 mm,左交互捻钢丝绳整绳破断拉力达784 kN,右交互捻钢丝绳整绳破断拉力达831 kN。使用表明该钢丝绳满足用户要求,可替代进口钢丝绳。
Coke quenching wire rope due to gas erosion, dust adhesion, red coke baking and other reasons, harsh working conditions on the overall performance of wire rope demanding. Introduction 6 × K36WS + IWRC-30 CDQ compacted strand ropes trial production process, given the CDQ lifting wire rope production technical requirements. The diameter of 8.0mm SWRH77A wire rod is selected as raw material for wire rope. The diameter of the semi-finished steel wire selected for the wire diameter of finished products is 3.40, 4.30, 5.30 and 6.50 mm respectively. Drawing using multi-pass, small compression rate method, the production of strands in the production line with shares of oil, steel wire coated with grease, strands twisted 79.2 ~ 83.3 mm, left cross-twist rope whole rope breaking tension of 784 kN, The entire rope breaking rope pull up to 831 kN. Use shows that the rope to meet user requirements, can replace imported rope.
