Abstract

The invention discloses a high-efficiency desulfurizer for molten iron, which comprises the following raw materials in parts by weight: 10-15 parts of sodium carbonate, 10-20 parts of sodium silicate, 4-8 parts of zinc chloride, 8-15 parts of sodium chloride, 5-12 parts of magnesium chloride, 7-15 parts of sodium nitrate, 15-20 parts of calcium oxide and 3-8 parts of potassium permanganate. The raw materials are pulverized, thoroughly mixed, and bagged to obtain the finished product desulfurizer. The high-efficiency desulfurizer for molten iron has the advantages of favorable desulfurization effect on molten iron, simple manufacturing technique and low production cost.

Description

technical field [0001] The invention relates to the field of desulfurizers, in particular to a high-efficiency desulfurizer for molten iron. Background technique [0002] Hot metal desulfurizer is an indispensable additive in the production process of modern iron and steel industry. With the rapid development of social economy, the demand for steel in all walks of life is getting higher and higher. The molten iron used in the production of steel must undergo a desulfurization process in order to ensure the quality requirements of the steel. Existing hot metal desulfurizers are of various varieties, but the desulfurization effect is not good. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a high-efficiency desulfurizer for molten iron, which can solve the problems existing in the prior art and has better desulfurization effect on molten iron. [0004] In order to solve the above-mentioned technical problems, a techni...
