本文就提高焊接钢管的成材率,提出“减壁”的设想,即原板减厚度档次和负偏差轧制的两步设想,研究“减壁”系统工程。生产实践证明,电焊管实行“减壁”按理论重量交货,提高成材率,可获得显著的经济效益。同时,对降低电耗,提高焊速,减少轧辊消耗等方面也有明显效果。鞍钢焊接管按提高成材率4％计算,每年可增产近万吨的焊接管。创650万元的经济效益,焊接管的“减壁”是可行的,经济效益是显著的,有必要全面推广。
This article to improve the rate of finished steel welded pipe, put forward the idea of “reduced wall”, that is, the original plate thickness reduction grade and negative deviation of the two-step concept of imagination, research, “reduced wall” system engineering. Production practice has proved that the implementation of “electric welding pipe” by the theoretical weight of delivery, improve the finished product rate, access to significant economic benefits. At the same time, to reduce power consumption, increase welding speed, reduce roller consumption, etc. also have obvious effects. Anshan Iron and Steel welded pipe by increasing the finished product rate of 4%, an annual increase of nearly 10,000 tons of welded pipe. Create 6.5 million yuan of economic benefits, welded pipe “to reduce the wall” is feasible, the economic benefits are significant, there is a need to fully promote.
