| Abstract: | Variety and structure of products in Xuan Steel are adjusted in 2007. The 6# caster of 120 t - converter - 130 t - LF - refining - furnace - 12 - flow square - billet - caster production line is turned to produce Large - scale square billet grade steel of 200 mmx 285 ram. To produce it, equipment is reformed and the grade production process optimized. After that it both reaches over 99 percent on the qualified ratio of hot heading upsetting of large - billet steel and qualified ratio of low - times examine. |
