1. Heating furnace: oriented silicon steel B23P095 heating furnace generally uses multi-layer heating, that is, the furnace chamber consists of multi-layer heating plate, the lowermost layer is the heating layer, the middle is the insulation layer, the uppermost layer is the insulation layer, the temperature and insulation time of each layer according to the thickness and composition of the billet, alloy composition and furnace lining structure.
2. Vacuum smelting: Vacuum smelting is the process of removing air bubbles and gases from the steel, which can reduce inclusions in the steel and improve the silicon and manganese content. The vacuum required in the production of silicon steel is 20 Pa. The effect is to reduce the gas in the molten steel to a minimum and to ensure fine grain size.
3.Refining: Refining is an important process for removing non-metallic inclusions and improving the silicon and manganese content in oriented silicon steel B23P095. The refining process is required to control the oxygen content below 1 ppm in the production of silicon steel B23P095.
4. Continuous casting: continuous casting is the vacuum refining of the steel through the heating, holding, cooling and other processes, so that the steel to a certain temperature, and then through the continuous casting equipment cast into round ingots. The production of silicon steel B23P095 requires the continuous casting process to control the cooling rate between 3 and 5°C/s to ensure that the temperature on the surface of the cast billet and the internal temperature are the same, so that it can be adequately cooled during the subsequent rolling process and reduce the possibility of defects such as folding, scarring and cracking in the billet during the hot rolling process. In order to obtain a flat and uniform finished billet, it is generally required that the finished billet is not allowed to have defects such as scratches, scars and bubbles after rolling.
5. Heat treatment: Heat treatment is to burn the iron oxide on the surface of the finished silicon steel billet to a certain thickness so that a dense and wear-resistant oxide layer is formed on its surface to improve its anti-magnetic properties and surface hardness. Heat treatment is required in the production of silicon steel to eliminate its surface defects and increase its wear resistance and corrosion resistance.
6.Packaging: In the production of oriented silicon steel B23P095, the packaging material is required to protect the silicon steel. The packaging material should be able to withstand a certain weight and mechanical strength to avoid damage during transport and handling; in addition, the packaging material should be easy to disassemble, clean, handle and store.
