Heating Conditions To Be Met of SSAW Steel Pipe

Before hot rolling of  steel plate, to heating not only improve the metal and plastic raw materials, reduce the deformation force, and convenient in rolling. In addition, the steel in the process of heating, the ingot can also eliminate the ingot bring some tissue defects and stress. Spiral welded steel pipe manufacturer for steel heating should be put forward requirements:

1. In the section of billet temperature uniformity and the length direction;

2. The steel temperature should meet the requirements of rolling technology;

3. The heating furnace's accident, long service life;

4. The furnace has a good technical and economic indicators;

5. Reduce the oxidation of the metal and decarburization, to prevent overheating and burning;
