| titleOfInvention | Overlaying welding manufacturing method for lug boss of hydrogenation reactor made of vanadium steel |
| abstract | The invention relates to a surfacing manufacturing method for a lug boss of a hydrogenation reactor for vanadium steel, belonging to the field of welding manufacturing. The surfacing method for manufacturing the lug boss of the hydrogenation reactor for vanadium steel comprises the following steps: preheating the vanadium-added steel base material to be more than or equal to 165 ℃, performing surfacing welding on the surface of the base material by adopting composite cold wire submerged arc welding, performing postweld heat treatment, and cooling to obtain a surfacing welding boss; the composite cold wire submerged arc welding is to adopt two identical welding guns to carry out welding, wherein each welding gun comprises 1 hot wire and 2 cold wires; the surfacing process parameters are as follows: the welding speed of the two main wires is 450-; the wire feeding speed of the front auxiliary wire is 200 +/-20 mm/min, and the wire feeding speed of the rear auxiliary wire is 1500 +/-50 mm/min; interlayer temperature 165-250 ℃; the maximum linear energy was 27.1 KJ/cm. The invention greatly improves the surfacing efficiency of the lug boss on the vanadium steel adding equipment under the condition of ensuring the product quality. |
