Steel-making alloy on-line baking method

Abstract

The invention discloses a steel-making alloy on-line baking method. A combustor along the tangential direction of the circumferential direction of a furnace body is arranged on a furnace body of an alloy baking furnace; a high-temperature airflow produced by the combustor bakes and heats an alloy along the tangential direction of the circumferential direction of the furnace body; and the baked alloy is discharged from a discharge hole of the furnace body so as to be directly added into a steel ladle. According to the steel-making alloy on-line baking method provided by the invention, the heating uniformity is effectively improved, the temperature of the whole alloy in the furnace body is ensured to be increased by heating, the baking and heating efficiency is improved, and the alloy can bequickly heated so as to meet the demand, so that the molten steel quality can be improved, the tapping temperature is reduced, the production energy consumption is effectively reduced, the service life of a converter is prolonged, the production efficiency is improved, the production cost is reduced, and the product economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of converter steelmaking production, in particular to an online baking method for steelmaking alloys. Background technique [0002] Alloy is an important raw material for steelmaking. The moisture content in the alloy directly affects the quality of molten steel and the tapping temperature. The amount of alloy material added varies from several hundred kilograms to several tons depending on the type of steel smelted. When it is added to molten steel above 1600°C, it needs to absorb a lot of heat to lower the temperature of molten steel. The alloy material is baked before use. On the one hand, the role of baking is to remove water and reduce [H] in molten steel. On the one hand, it can reduce the temperature drop of molten steel during the process of adding molten steel and avoid increasing energy consumption. The alloy baking process has been widely used in the steelmaking process and plays an important role...
