Optimization And Reformation Of 1500mm Broadband Equipment

Laiwu Steel Strip Factory of broadband 1500 mm production line in 2004 2005 started, hot test is successful, has been put into operation for ten years. With the production, production capacity has been constantly enlarged, part of the equipment to malfunction, can not meet the requirements of production, and production process of precision and function of the equipment is also proposed new requirements, so it is necessary to optimize the corresponding part of the equipment.The author during the on-the-job graduate student, mainly in charge of finishing mill in the production line of the previous device, equipment defect management is mainly reflected in the following aspects: 1, serious damage of furnace roller bearing seat, the cooling effect is not good; out door damage frequently, serious deformation beam connections, connections stretching deformation. Accuracy of 2, roughing mill rolling thickness control is not high, the transmission connection shaft failure rate is high. 3 hot rolled coil, high rate of equipment failure, leading a flying shear guide wheel wear, frequent replacement, profile control effect is not good.In view of the above equipment problems, project research and analysis, finally found the cause of equipment damage or accuracy is not high, a retrofit scheme was put forward accordingly, two overhaul of equipment use in 2012 and 2013, a gradual transformation of the existing equipment, after the transformation of equipment life is greatly prolonged, the equipment failure rate is reduced effectively, the quality of the products improved significantly. By equipment modification, effectively reduce the cost of procurement of equipment and maintenance cost, but also improve the market competitiveness of products, but also produced a significant social benefits, reduce the labor of workers.
