Baosteel's special steel production worked out a direct rolling process

Baosteel steel forgings and further enhance the competitiveness. Recently, the reporter learned from the Steel Division: the company's own exploration of the 1300 tons diameter forging machine a successful direct rolling production process has changed the traditional sense of "fast track forging forging +" two direct rolling process, significantly reducing production costs, and product quality without fluctuation.

 Special Steel Division has two fast forging machine and a 1300 tons diameter forging machine, mainly for the production of sophisticated field of special forgings. According to the traditional production process, a number of high-end varieties must be "fast forging + tracks forging the" two direct rolling processes to produce. Since the outbreak of the global financial crisis, the face of market downturn, the pressure of high cost, special steel division to actively think about cost efficiency and enhance competitiveness of products, effective way to challenge the two direct rolling process.

 Two fire can become useful in the production variant of the product volume increases, the more stable inner quality, but also to remedy the defects of the disposal of surface quality, to the user on the surface, the high accuracy requirements. From the forging machine of the "brothers" to join hands to "go it alone", a direct rolling process significantly increases the risk and pressure.

 In the absence of experience, can learn from the case, Forging, manufacturing, steel mills, etc. a team, using many years of production technology, starting from the development of new steel ingot, forging machine developed in line with track, "appetite" to ensure that veteran ingot. In production practice, the team members to carry out a large number of experiments, the accumulation of valuable data, to optimize and improve the process laid the foundation. Through hard work, a direct rolling process is improving, made ??a breakthrough.

 At present, the "go it alone," the 1300 tons of production to achieve stability diameter forging machine capable of producing high-end fire using a set of specifications than in the past from the range increased by 10 percent. More importantly, a direct rolling reduces costs and energy consumption, the average cost per tonne reduced by 20% or more. User feedback showed that: the performance and stability, product quality and fully meet the production needs
