River steel of Xuanhua steel's successful 7.5# angle
Recently, the river steel of Xuanhua steel rolling plant small operation success at 7.5# angle, fill a gap in the product specifications of the company. At present, the 7.5# angle is mass production, product quality reaches the South fence and network standards. Development of the 7.5# angle, mill load due to rolling the bigger increase, carried out to bring the force equilibrium mill, required to pass design in high standards. For, small rolling factory technicians through on mill the sorties hole type precision calculation, on rolling hole type implementation has improved optimization; draws the sorties processing figure, and on processing Hou of hole type do online Qian of precision measurement acceptance, avoid has deviation of appeared; on process parameter for amendment, developed out the varieties specifications of heating temperature and released temperature; in pre straightening straight system increased pre straightening straight pressure roll device, change has pre straightening straight way, guarantees has finished angle of straight degrees and shear quality; for larger specifications angle exists straightening straight difficulty, On straightener system implementation optimization, amendment and optimization straightening straight roll drawings, improved processing method, effective avoid has side bent, and Alice head, and angle angle deviation, problem of occurred, improve has straightening straight effect and efficiency, for production provides has guarantees; development process in the, on try rolling products appeared of problem timely adjustment process parameter, developed effective of production organization programme, ensure has with more short time debugging out qualified products.
2016-January, Ho Xuan steel steel steel mill to seriously implement Group and company level ' spirit, focusing on increasing the profile of angle steel product research efforts, to create differential competitive. 1287 monthly total production of finished steel orders, production reached 42016.25 tons, in which steel ratio to 54.42%, a new record levels high. Since 2016, product upgrade as the central focus of the factory came to further refine the production Division and deepen the product positioning, key profile angle steel products production line, speed up the adjustment, structural adjustment and enhance the quality of work, building efficiency products, release full production potential. Work in the, the factory deepening produced line on standard, to production research for mainline, for production in the of temperature control, and process operation, and equipment precision, important link and effect factors, carried out has improve rolling line job rate, and improve steel timber rate, and set feet rate, and reduced rolling line process accident, series factory, and job district focus subject research, factory professional research and job district post research seamless convergence, strengthening the link effective tube control, strictly implementation standardization job, especially in mill Assembly, and temperature control, key points do precision control, Production capacity is fully released. Enhanced angle fine positioning, implementing process quality responsibility system, through process improvement, thinning operations, tightly controlled means of surface quality and dimensional accuracy research, product packaging and labeling management to meet market demand. Strengthen equipment management, post inspection and combination of professional checking, combining management and the professional management of process equipment, improving device capabilities, improve device accuracy using the rolls for interspersed with repair, effectively reduce the scheduled maintenance time, creating the conditions for stability along the line.
