12月20日金堂钢管分公司40穿孔机组项目按节点安全优质完成机组热试，为分公司开拓高端市场、提升竞争力奠定了坚实基础!

        “开始！”12月20日，随着金堂钢管分公司40穿孔机组项目负责人一声令下，一支火红的钢坯从加热炉吐出，通过辊道，转瞬间被穿孔机咬入，顺利穿孔成毛管，标志分公司新建40机组热负荷试车成功。

        连日来，分公司40机组项目部一手抓疫情防控，一手抓工程建设。为保证试车工作的顺利完成，项目部组织各参建单位和部门梳理相关制约因素，从完善风险方案、合理分配人力、优化工作任务安排等多个方面入手，确保40机组试车过程中每个细节措施到位、责任到人。

        从12月20日零时起，项目部安排步进炉升温，9时开始送料，11时各岗位人员到位准备。各岗位人员一边做好穿孔准备，一边进行最后安全确认。“加热炉加热段，均热段温度满足生产要求；穿孔机前后台满足生产要求；孔型参数满足生产要求……”试车现场不时响起各岗位人员关于试车的准备情况。准备工作完成后，穿孔线上各操作人员撤离到安全区域等候，随后穿孔机欢快地运转起来，现场干部职工怀着无比激动的心情，见证这一历史时刻：当红色的圆坯快速穿过穿孔机“吐”出钢管成品时，顿时现场响起热烈的掌声。

        据悉，此次试轧的圆坯规格为Φ50mm、钢号20号，轧制规格分别为Φ52×7mm、Φ52×5.5mm、Φ52×4.7mm，经检查尺寸及表面质量均满足工艺要求。热试后，分公司将持续完善设备及参数的调试和优化等收尾工作，加快推进新机组达产达效。

On December 20th, the 40 perforated units project of Jintang Steel Pipe Branch completed the hot test of the units according to the safety and quality of the nodes, which laid a solid foundation for the branch to explore the high-end market and enhance its competitiveness!

'Go! On December 20, as the leader of the 40 perforated unit project of Jintang Steel Pipe Branch gave the order, a red-hot billet was discharged from the heating furnace and passed through the roller table. In a twinkling, it was bitten into by the puncher and perforated into capillary tubes smoothly, which marked the success of the thermal load test of the new 40 units of the branch.

Over the past few days, the project department of the 40 units of the branch has been focusing on both epidemic prevention and control and project construction. In order to ensure the smooth completion of the test work, the project department organizes all the participating units and departments to review the relevant constraints and start from various aspects such as perfecting the risk scheme, rationally allocating manpower, and optimizing the arrangement of work tasks, so as to ensure that every detail measures are in place and responsibilities are assigned to people during the test work of 40 units.

From 12:00 on December 20, the project department will arrange the stepping furnace to heat up, start feeding at 9:00, and get all the staff ready at 11:00. The personnel in each position prepare for perforation and conduct final safety confirmation. "In the heating section of the furnace, the temperature of the soaking section meets the production requirements; Puncher front and back to meet the production requirements; Pass parameters meet production requirements..." The test site from time to time sounded each post about the test preparation. After the completion of the preparation work, all operators of the perforation line evacuated to the safe area to wait, and then the puncher began to run happily. The cadres and staff at the site, with great excitement, witnessed this historic moment: when the red round billet quickly passed through the puncher and "vomited" out the finished steel pipe, the scene immediately erupted into warm applause.

It is understood that the rolling of round billet, steel grade 20 specifications for Φ 50 mm, specifications of rolling Φ Φ 52 x 7 mm, respectively (52, Φ 52 x 4.7 mm x 5.5 mm, through inspection the size and surface quality meet the technological requirements. After the hot test, the branch will continue to improve the equipment and parameters of the commissioning and optimization of the final work, accelerate the new units to achieve production and efficiency.
