太原钢铁厂中型轧钢车间由於过去对轧制异型断面的钢材很少,又没有一套系统完善的技术操作规程,在1955年1—7月轧制新产品槽钢时质量问题严重。如7月份质量计划是98％,而实际只达到96.64％,仅这一次的废次品给国家造成的损失即达5000多元;更严重的是轧一次断一次辊子,严重影响了轧机的寿命,威胁着产量与成本任务的完成。这个问题给轧钢车间在修订与贯彻技术操作规程中,提出了新的和迫切需要解决的课题。
Medium-sized steel mill in Taiyuan Iron and Steel Plant due to the past on the profile of the rolling special steel, there is no set of sound technical procedures, from January to July 1955 rolled new product channel quality problems serious. Such as the quality plan in July is 98%, while the actual only reached 96.64%, only this time the waste products to the country caused the loss that amounted to more than 5,000 yuan; more serious is rolling a roller once severely affected the life of the mill, Threatening the completion of production and cost tasks. This issue raised new and urgent issues to be solved in the revision and implementation of technical operation procedures for rolling shops.
