If the heating situation of the bent pipe cannot be controlled during processing, it will have some impact on the product. Improper process control during processing can also greatly affect the strength of the product. In severe cases, cracking may occur. The editor mainly talks about the requirements for the distance between the jaws of the product during processing. Interested friends can take a look with the editor!
In fact, the distance between the jaws of the product is determined by the thickness of the steel plate material processed. If the thickness of the steel material is thicker, the required distance will be smaller. The distance between the jaws after forging is also determined by the thickness of the steel. In fact, if the distance is too small, it can lead to overlapping welding, but if the distance is too small, it can also cause a large temperature difference along the welding section. The distance of top forging is also determined by the thickness of the steel. If the distance of top forging is too small, it will reduce the pressure on top, making it difficult for some metal oxides to be discharged and left in the welding joint during operation. The fire holes generated during burning inside cannot be completely closed. However, if the distance of top forging is too large, it will also cause too much pressure on top, and some metal oxides will be completely discharged, which will reduce the welding strength during product processing.
