Problems solved by technology

[0002] The application of copper in iron and steel worldwide is mainly added in the form of copper and iron. Due to the aforementioned reasons, the yield of copper is low and the effect of microalloying is limited.
The application of manganese in steel is very mature, and the most effective addition form is manganese nitrogen alloy or ferromanganese nitride, but the biggest problem is that the price of manganese nitrogen alloy or ferromanganese nitride is expensive, which increases the raw material cost of steel products. It affects the competitiveness of products, so the application of manganese in steel is increasingly suppressed
[0003] Due to the uneven development level of the iron and steel industry, some enterprises have high oxygen and sulfur content in the iron water. When copper and iron are added, copper oxide and copper sulfide will be formed and copper will be consumed. Manganese oxide will also be generated when manganese nitrogen alloy is added. It will not only reduce the recovery rate of manganese and copper, increase the production cost, but also seriously affect the quality stability of steel products, which in turn will affect the application of manganese and copper products in steel

Embodiment

[0040] After finely grinding 100kg of manganese oxide powder with a manganese content of 64% to -100 mesh, add 27kg of graphite, 0.5kg of iron powder, 1.5kg of polyvinyl alcohol, and 0.5kg of metal silicon according to the carbon distribution coefficient of 0.75, and dry mix for 25 minutes until uniform , add an appropriate amount of water and wet mix for 25 minutes until uniform; apply a pressure of 10 MPa to the wet-mixed mixture and press it into a wet material block of 50 mm × 50 mm × 30 mm. The wet material block is heated at 200 ° C and dried for 40 hours, to obtain dry blocks; carry out normal pressure high-temperature carbonization of dry blocks and calcination in a nitriding furnace, the calcination temperature is 1550 ° C, the calcination time is 28 hours, the sintered blocks are cooled to below 100 ° C with the furnace, and the Manganese-nitrogen alloy products with a nitrogen content of 16.93% and a manganese content of 77.58%.

Abstract

The invention discloses a method for industrially producing manganese-copper alloy. The method comprises the following steps that raw materials, comprising, by weight, 0-100 parts of copper oxide, 0-100 parts of 100-mesh manganese oxide, 0.3-0.7 part of zinc chloride, 0.3-0.7 part of ferrous sulfate and a sulfo chalcophile agent, 0.5-1.5 parts of oxyphile agents and 1.5-2.5 parts of binding agentsare uniformly mixed with water, wherein the total amount of the copper oxide and the manganese oxide is 100 parts, and the coefficient of the zinc chloride with carbon is 0.70-0.80; and 2, the mixture is pressed and uniformly mixed into a material block, and the material block is dried, calcined and cooled under the protection of nitrogen to obtain the product. The product prepared by the methodcan obviously improve the manganese and copper recovery rate when the copper alloy product is applied to iron and steel, and meanwhile, the raw material cost of the manganese-copper alloy in steel production is reduced, and the method has good economic and social benefits.
