Problems solved by technology
Because these materials are independent of each other during use, they cannot deoxidize the molten steel together, so that the speed of deoxidation and submerged arc is slow, so the deoxidation effect is not good, and the cost is high

A deoxidizing slag-forming agent for ladle furnace contains Al particles (15-35 wt portions), C powder (10-40), powdered silicon carbide (15-40), Si-Ca-Ba powder (15-35) and other material containingSi (5-15). Its advantages are high deoxidizing speed and arc smothering speed, and low cost.
Description
(1).Technical field [0001] The invention belongs to the field of steelmaking, in particular to a deoxidizing slagging agent for a ladle furnace. (2). Background technology [0002] In the steelmaking process, due to the existence of a large number of oxides in the raw materials, the steelmaking process is an oxidation reaction process, and oxygen blowing is also required during the smelting process. Therefore, it is often necessary to deoxidize the molten steel during smelting. Reduce air bubbles, inclusions, harmful elements and structural defects in billets. At present, the deoxidation of molten steel is usually carried out in the ladle, and the deoxidizer is often used to deoxidize the molten steel by putting carbon powder, ferrosilicon powder, calcium carbide, aluminum particles, and silicon carbide powder into the ladle respectively. This method needs to throw the above-mentioned materials into the ladle with a tool, and in the process of throwing, a large amount of sm...
