Before the steel is hot rolled, heating the raw material not only improves the mental plasticity, reduces the deformation force, but also facilitates rolling. In addition, during the heating process of the steel, some structural defects and stresses caused by the ingot can also be eliminated for the steel ingot.
Spiral steel pipe manufacturers should put forward the requirements for the heating of steel:
1. The heating of the
spiral steel pipe has a uniform temperature on the section and length of the billet;
2. The steel temperature should meet the requirements of the rolling process;
3. The heating furnace of the
spiral steel pipe has few accidents and long service life;
4. The heating furnace of the
spiral steel pipe has good technical and economic indicators;
5. Reduce the oxidation and decarburization of metals to prevent overheating and overburning;
