| titleOfInvention | Total-converting steelmaking method of electric furnace |
| abstract | The invention discloses a total-converting steelmaking method of an electric furnace. The method achieves the purposes of energy saving and consumption reducing through the working procedures containing adjustment for ratio of raw materials and strict control for the converting process. The method specifically comprises the following steps of: controlling the proportion of molten iron to be 71-79 percent; adding steel scraps through a furnace mouth for one time, and adding the molten iron through an iron exchanging mouth for two times; preheating, warming and decarburizing the steel scraps and molten steel in a furnace through a nozzle of an oxygen-burning system 3 installed on a furnace wall; during converting, regulating a corresponding gear according to demands, meanwhile converting with a furnace door oxygen gun, and making the converting efficiency to be maximized; adding slag making materials such as lime into the electric furnace to make slag; and when the molten steel achieves the temperature and components needed by steel grades, carrying out ladle deoxidization for steel tapping. Compared with the general steelmaking method of the electric furnace, the total-converting steelmaking method of the electric furnace has the advantages that electrode heating is cancelled, the consumptions of the electric energy, electrode and steel scrap are greatly reduced, the smelting cost per ton of steel is greatly reduced, the pollution is decreased, meanwhile the contents of harmful elements in the steel are reduced, and the product quality is increased. |
