Application Practice of Direct Rolling Technology for Rod and Wire Rod
This article introduces the theoretical basis and research status of direct rolling.The key to achieving direct rolling lies in improving the discharge temperature of continuous casting billets and ensuring the opening temperature.Many domestic steel companies have already applied direct rolling technology,which not only reduces process costs but also improves product performance to varying degrees.Combining the application examples of direct rolling technology and double high-speed bar,it is summarized that thermal stress control and deformation control during the rolling process are still urgent technical problems which need to be solved.In the future,direct rolling technology will put forward higher requirements for automation,intelligence,energy conservation and emission reduction.
