Example Embodiment
[0010] Example 1: Silico-manganese fly ash deoxidizer for steelmaking. The weight parts of its constituent raw materials are: quartz sand 100, calcareous shale 12, fly ash 22, fluorite 12, charcoal 4, waste aluminum powder 7, Attapulgite 28, black manganese ore 12.
[0011] The preparation method of silico-manganese fly ash deoxidizer for steelmaking includes the following steps: weigh each raw material according to the weight of the constituent raw materials, and put them into a submerged arc furnace for smelting. The smelting temperature is 2100-2500℃, and the smelting time is 2-3 After hours, crush to 70-90 mm, remove impurities, and it is the finished product.
[0012] The following is a deoxidation test, the test steel is low carbon steel, used in the 2# furnace, 1.36kg / t steel
[0013] Hot metal conditions:
[0014] [S]S% [P]% 0.039-0.0320.190-0.152
[0015] Deoxygenation result:
[0016] Serial number Furnace number Addition of the invention (kg) Oxygen content (PPm) 1...
