Preparation method of hot-rolled wire rod BGHS380 for welding rod

The invention discloses a preparation method of a hot-rolled wire rod BGHS380 for a welding rod. The preparation method comprises the following steps that in the tapping and refining process, the components are regulated in a required range to ensure the corresponding mechanical properties of the prepared wire rod; and cooling is carried out by using a Stelmor line in the preparation process, thecooling speed is controlled within 0.5 DEG C/S, so that the mechanical property of the wire rod is further improved. The preparation method of the hot-rolled wire rod BGHS380 for the welding rod has the advantages of being simple, easy to operate, low in cost, good in mechanical property of the prepared wire rod and the like. 本发明公开了一种焊条用热轧盘条BGHS380的制备方法，该方法通过在出钢及精炼的过程中，将各成分调整在要求的范围内，以确保制得盘条的相应力学性能，而且在制备过程中采用斯太尔摩线冷却，并将冷却速度控制在0.5℃/S以内，进一步提高盘条的力学性能。该焊条用热轧盘条BGHS380的制备方法，具有方法简单、易于操作，成本低廉，而且制得的盘条力学性能佳等优点。
