Since the beginning of this year, the steel rolling division of Shougang Tonggang has been guided by market demand, continuously promoting the upgrading of product structure and actively broadening the rolling blank type. Recently, the division's fine bar line successfully rolled 180 billets this year, providing strong support for the company's product upgrade.
In order to ensure the success of this rolling, the division held a special meeting according to the process requirements and product characteristics of the 180 billet to discuss the difficulties in the process of 180 billet rolling control. A research team was set up to sort out the rolling process, systematically investigate the equipment and key control points affecting production, and formulate effective measures item by item to successfully roll.
Before rolling, the division focuses on process management to carry out descaling machine lead plate adjustment, mill guide groove adjustment, roll processing and other work to ensure that the production process requirements are met. Organize maintenance personnel to restore the functions of 2 rolling mills, transform and expand the original transmission cabinet, inspect 2 DC motors, test the insulation of electrical circuit cables, and install DC motors. Organize the rolling post personnel to readjust the position of the feeding bench trolley and test the ability of the feeding hydraulic cylinder, readjust the opening degree, step distance and automatic tapping program of the hydraulic cylinder of the walking beam of the heating furnace, so as to meet the needs of the 180 billet production and create conditions for the realization of production.
In the rolling process, the division's eyes are inward, giving full play to the spirit of unity and cooperation between technicians and production backbones, strengthening the management of on-site process and technical operation procedures, and implementing a special inspection system for billet entry into the furnace, heating temperature control, steel rolling adjustment, finishing collection and other links, so that each process is strictly controlled, job responsibilities are implemented layer by layer, and the product is successfully rolled.
According to statistics, 28 pieces and 70 tons of 180 billets were rolled this time, with a total rolling diameter of 22 round steel and 67 tons of finished products. After inspection, the surface quality, dimensional accuracy and performance of the product meet the standard requirements. The successful rolling of the 180 billet not only further broadened the company's product structure, but also provided strong support for the continuous expansion of the market.
