Embodiment Construction

[0013] Crush the raw materials into a particle size of 20-50mm, then weigh 200 kg of silica, 350 kg of limestone, 100 kg of fluorite, 150 kg of barite, and 200 kg of coke. After weighing, mix them evenly and add them to the shaft furnace in batches Internal smelting, after the smelting, open the furnace eye, pour the silicon-calcium liquid in the furnace into the ingot mold, and release the mold after cooling to obtain the silicon-calcium-barium pure steel agent. The composition of this product after testing is Si≥16.25%; Ca≥23.46%; Ba≥3.56%.
