Research of ultra-fine bainite X80 pipeline plate for gas compressor station

摘要：

　　This paper reports on the research of low temperature(-51℃)X80 pipeline plate used for gas compressor station.In order to satisfy the performance requirements of low temperature X80 pipeline plate,an optimized rolling and cooling process was developed to achieve ultra-fine bainite microstructure and stable mechanical properties.The results showed that by improving the final roughing pass reduction prior to the intermediate holding and the per pass reductions during finish rolling,up to 20%and 10%respectively,the austenite grain can be refined and uniformed completely.The optimized cooling process application after finish rolling guarantees the steady control of the final ultra-fine bainite microstructure with optimum M/A phase for X80 plates.The 10000 metric tons plates produced by this process achieved good flatness and excellent low temperature toughness
