2. Chemical composition of BB503C blast furnace shell steel plate.
3. Mechanical properties of BB503C blast furnace shell steel plate.
4. BB503C blast furnace shell steel plate manufacturing process and quality control.
The manufacturing process of BB503C blast furnace shell steel plate mainly includes smelting, continuous casting, rolling, heat treatment and other links. In the smelting process, the electric furnace + LF VD refining process is used to ensure the stability and purity of the chemical components. In the continuous casting process, the uniformity of the structure and properties of the steel plate is ensured by controlling the internal quality and surface quality of the billet. The heat treatment process adopts quenching + tempering treatment to eliminate internal stress and improve the mechanical properties and corrosion resistance of the steel plate. In terms of quality control, BB503C steel plate undergoes strict inspection procedures, including chemical composition analysis, mechanical property testing, dimensional and surface quality inspection, etc. Only steel plates that meet the requirements of the standard can be shipped**.
