石油部第四工程公司金属结构厂,承担了海洋平台隔水套管和桩的预制工作。它是采用36毫米厚的钢板卷制成管再焊成单节。然后,由各节组对成所需长度。纵缝和环缝采用“X”型坡口双面焊接成形。当焊接另一面时,需对原焊道进行清根处理,以保证焊接质量。开始,清根这道工序是采用人工手砂轮磨削,工作量和劳动强度都很大。而且造成粉尘和铁末污染,噪声很大,影响工人的身体健康。针对这种情况,该厂发动群众在短期内革新成功了纵缝和环缝清根机各一台。经过三个多月的使用,共清根1780道焊口,计4896延长米。共节约砂轮6609片,减少了粉尘5.66吨,节约费用达三万余元。提高了经济效益和清根
Ministry of Petroleum Engineering Company No. 4 metal structure plant, assumed the offshore platform riser casing and prefabricated work. It is made of 36mm thick steel tube rolled into a single tube and then welded. Then, by each section group into the desired length. Longitudinal and annular joints are formed by “X” groove double-sided welding. When the other side of the welding, the original weld clearance root treatment required to ensure the quality of welding. At the beginning, this process of root cleaning is grinding with artificial hand wheel, which requires a lot of work load and labor intensity. But also cause dust and iron pollution, noise is very large, affecting the health of workers. In response to this situation, the plant launched the masses in the short term successful reform of the longitudinal seam and ring seam root clearance machine each one. After more than three months of use, a total of 1780 tunnel root clearance, 4896 extension meter. A total of 6609 pieces of grinding wheel, reducing the dust 5.66 tons, saving costs up to three thousand yuan. Improve economic efficiency and clear roots
