At present, it has 5 finishing rolling production lines and 2 hot rolling production lines: one is 60, 90 piercing machine, which mainly produces stainless steel pipes with an outer diameter of 22mm-750mm; the other is 325mm ASSRL pipe which rolling machine adopts mandrel pre-installed limit Small cycle, three-level computer-controlled automation system. The stainless steel plate hot rolling production line was completed on December 28, 2011 and completed on July 11, 2014. In the first hot-rolling test on July 1, 2014, qualified hot-rolled coils rolled off the production line smoothly, which is still a rare precedent in the world's hot-rolling mills. This once again proves ZLYS' excellent management hot ability and profound technical background. The main equipment of the rolling mill includes a walking beam heating furnace, a high-pressure descaling machine, a vertical roller roughing mill, a steckel mill (rolling mill), a laminar flow cooling equipment, a coiling One machine. The who le set of equipment is designed and provided by Itochu, Japan. Our factory adopts a unique Steckel rolling mill, which has the following salient features: The coiling furnace can heat and keep warm the steel strip, which is suitable for rolling high alloy steel and rolling thin material. In addition, effective measures such as advanced automatic width control system (AWC), automatic thickness control system (AGC), bending roll system, and work roll shifting system are adopted to ensure product quality. The annual output of the f is 600,000 tons of stainless steel. The product specifications are: thickness 2.0~12.7mm, width 800~1600mm, coil weight Max 30 tons. The second cold rolling production line started construction on December 1, 2013, and was completed operation and put in March 2015. It mainly includes two 20-roll rolling mills (ZRM), one annealing and pickling production line (CAPL), and coil preparation line (CBL). One set, one set of slitting line (STL), six sets of roll equipment. Coil packing 1 set. The factory product specification is (0.3~5.0)*(1000~1600)mm. The French DMS 20-roller Sendzimir mill was introduced; all CAPL equipment was imported from Germany, the Netherlands and other European countries. The production line laser welding machine is the first in the domestic stainless steel industry. Install degreasing equipment to ensure multi-steel production. The online application of SPM and TL effectively reduces the production cost.
