异型无缝钢管主要用在农业机械、运输车辆、纺织、轻工以及有关国防科研等方面,现就我厂试制情况,对异型无缝钢管的生产作一简要介绍。 (一)异型无缝钢管生产工艺: 1.工艺流程。无缝管坯→打头→酸洗→涂磷→皂化→拔制→退火→…周期循环→拔至异型断面所需管料尺寸D_n×S_n →检验→退火→锤头→酸洗→涂磷→皂化→拔制异型成品→矫直→检验→精整(切头切尾)→复验→涂油包装入库。 2.各工序操作要点。在拔至管料尺寸D_n×S_n之前,所有工序和一般无缝钢管相同。
Shaped seamless steel pipe is mainly used in agricultural machinery, transport vehicles, textiles, light industry and related national defense research, the trial is now my plant situation, the production of shaped seamless steel pipe make a brief introduction. (A) shaped seamless steel pipe production process: 1. Process. Seamless tube → head → pickling → Tu-sa → saponification → drawing → annealing → ... cycle → pull to the profiled section required tube size D_n × S_n → test → annealing → hammer → pickling → Tu-P → Saponification → Extracted shaped products → Straightening → Inspection → Finishing (cut to tail) → Retesting → Oiling packaging. 2 points of operation of the process. Before pulling to the pipe size D_n × S_n, all processes are the same as those of ordinary seamless steel pipe.
