Liu Steel Billet, "a Fire Timber" Construction And Follow-up Engineering And Technology Research

In 1997,the converter steel of Liu Gang was realized 100% continuous cast. Other rolling mills of rolling system still adopt "Roll in Two Heat" technique except Medium Plate Mill realized "Roll in One Heat" .How to utilize existing equipment to carry on the proper transformation and realize 100% "Roll in One Heat" of steel strand is the important subject for research in front of us to achieve the purpose of energy-saving and cost-reducing, rolling yield-improving, economic efficiency-increasing. Through study on the 100% "Roll in One Heat" technology, we find Liu Gang is imbued with the condition to realize the 100% "Roll in One Heat" of steel strand. For this reason, we implement technological transformation to Medium rolling mill, Small rolling mill and wire rod mill respectively; adjust and optimize the steel rolling technology structure and variety structure of rolling system during the "Ninth Five-Year Plan" .Through draw the successful experience, we carry on the research and application to the hot delivery and charging technology which obtained success on technological transformation too.Though making small progress on technology and equipment modernized research and application which appear backward in the past two years,Liu Gang never stops the research and application for the modernized technology and equipment which were succeeded in using to the transformation of Medium Plate Mill and light continuous rolling bar.The research and plan on modernized transformation project of high-speed wire rod which is the high-new technology, modern technology and equipment as "Tenth Five-Year Plan" scheming comes into big use in Liu Gang. The transformation scheme on high-speed wire rod is based on high level:the annual produce of single strand is 600,000 ton.The rolled product line speed is 120m/s, and the key equipment we imported is the most advanced stage facility in the world which incorporated the modern technology and equipment,and applied the computer, modern communication technology modern technology and equipment, and applied the computer, modern communication technology and information technology.
