Optimization of the Wall-Increasing Process of the Stretch- Reducing Mill Shows Results

Dalipal actively implements the concept of green development, focuses on innovation and efficiency, taps potential, and improves quality and efficiency. Recently, after repeated tests, the company has made a new breakthrough in optimizing the wall-increasing process of the stretch-reducing mill. The yield rate of oil casing 5-1/2 series products has increased by more than 1.5%, and the manufacturing cost has been reduced by approximately 52.5rmb per ton; the average yield rate of oil cylinder pipe products has increased by about 2%, and the manufacturing cost has been reduced by approximately 70rmb per ton. The optimization of the wall-increasing process of the stretch-reducing mill improves the yield rate while reducing manufacturing costs. This provides more adjustment directions for the company's small-batch contract production process, and also improves the flexibility of the production organization and on-site operation rate.
