Research on Transformation of Bar Production Line Based on New National Standard
In order to meet the new requirements of the new national standard GB/T1499.2-2018 on the metallographic structure and properties of hot-rolled ribbed steel bars,achieve high-quality development of enterprises and improve product competitiveness,this paper puts forward a scheme of transforming the original bar production line into a high speed bar roll-ing line by the comparative study of the two rolling modes of high-speed rolling and split rolling in the fully continuous bar production line and combining with the layout and process equipment of the raw bar production line at Yueshao Iron and Steel Plant.The green production of alloy reduction has been successfully realized through the technological transformation of multi-stage graded cooling of the cooling system,so that the transformation goals of high quality products,green process and intelligent steel mill have been achieved.
