On June 25, Zhejiang Pacific Steel Pipe successfully produced 86CrMoV7 ultra-long large-caliber high-carbon seamless pipe for the first time. After testing, the wall thickness deviation, outside diameter deviation, straightness per meter, total length and other indicators meet the requirements.
86CrMoV7 steel due to its high carbon content, high alloy content, resulting in easy cracking in the rolling process, so for the rolling of 86CrMoV7 seamless pipe, Zhejiang Pacific Steel Pipe General Manager Department attaches great importance to the arrangement of research institute, technology department and hot rolling main backbone as the core set up a research group, and held a special meeting. Fully discuss the risks and countermeasures of rolling 86CrMoV7 seamless pipe, finally determine the heating technology, rolling process, and mold parameters, and track and guide the whole rolling process. The final rolling process is smooth and the first rolling of 86CrMoV7 is successfully completed.
86CrMoV7 steel as a large cold rolling work roll steel has been widely used in the industry, the successful production of large caliber thick wall 86CrMoV7 seamless pipe, marking a new breakthrough in the field of rolling varieties in Zhejiang Pacific steel pipe, a new upgrade in rolling technology. Zhejiang Pacific Steel Pipe will continue to develop new varieties with a meticulous, rigorous and scientific attitude, and develop new processes to achieve greater breakthroughs in new product efficiency.
