An annual output of 4.2 million tons hot-rolled strip steel plant process design
Abstract：According to the design mission requirements, an annual output of 4.2 million tonsfor hot rolled strip plant process design. Design reference steel hot strip production line 1780,in accordance with the mission statement production requirements, select Typical products 16MnR, product thickness of 4mm, width of 1520mm.Design elements include product solutions and production program development, metal balancing and process development, material selection, selection mill auxiliary equipment selection, passes the determination of procedures to determine pressure, velocity calculation, calculation of the temperature drop, roll Model calculations, force and energy parameter calculation, checking the roll and the motor capacity check.To ensure the smooth rolling, four-high reversing roughing mill, the maximum rolling force of 4000t. Finishing mill with full hydraulic pressure device AGC system, hydraulic cylinder stroke is 120mm, the rapid increase of pressure, and improve the precision of thickness.Currently AGC thickness control system mathematical model of continuous improvement, constantly improve control accuracy. Where F1, F5 ~ F7 to conventional mill; F2 ~ F4 for the PC mill, F4 ~ F7 with ORG device F1 ~ F7 finishing mill  
process using hot oil lubrication technology. F1 ~ F7 using sliding trolley quick change of work rolls, reducing the time to stop rolling. Designed annual production capacity of 4.2 million tons.
