Heating requirements for spiral steel pipes
Before hot rolling of steel, heating the raw materials not only improves the plasticity of the metal, reduces the deformation force, but also facilitates rolling. In addition, during the heating process of steel, certain structural defects and stress caused by the steel ingot can also be eliminated. The requirements that spiral steel pipe manufacturers should put forward for steel heating:
1. The heating of the spiral steel pipe has a uniform temperature on the cross-section and length direction of the blank;
2. The steel temperature should meet the rolling process requirements;
3. The spiral steel pipe heating furnace has fewer accidents and has a long service life;
4. The spiral steel pipe heating furnace has good technical and economic indicators;
5. Reduce oxidation and decarburization of metal and prevent overheating and overburning;
