我公司重50t运送液体的天车轨道全长370m。由于连接接头较多,天车运行时震动剧烈,致使钢水包内的液体外溢,并使天车各零部件不断损坏,直接影响生产正常进行。为此,对轨道上的所有连接接头进行了修理焊接。经过一段时间的运行考核,证明焊后质量是令人满意的。现将焊接工艺介绍如下。焊前准备 1.用规格为200×200×400mm的方木将轨道垫平。在垫方木时,应每隔3m垫一根,当遇到接头时,在接头两侧300mm处的下方各垫一根。
My company weighs 50t transportation of liquid Crane track length of 370m. Due to the large number of connecting joints, the crane vibrates violently during operation, resulting in liquid spillage in the ladle and continuous damage to the various components of the crane, which directly affect the normal production. To this end, all joints on the track were repaired and welded. After a period of operational assessment to prove the quality of the welding is satisfactory. The welding process is as follows. Preparation before welding 1. The specifications for the 200 × 200 × 400mm square rail pad will be flat. When the mat square wood, should be a pad every 3m, when the connector, 300mm at both sides of the connector at the bottom of a pad.
