Abstract

The invention relates to a manganese-iron alloy. The manganese-iron alloy comprises the following components by weight percent: 50-70% of manganese, 3-5% of silicon, less than 1.0% of carbon, less than 1.0% of phosphorus, less than 0.02% of sulfur, less than 2% of other impurities and the balance of iron.

Description

A kind of manganeseirom
Technical field
The invention belongs to metal material field, refer to especially a kind of for the manganeseirom as sweetening agent or reductor.
Background technology
Along with the development of Iron And Steel Industry, many high quality, high-quality steel alloy are developed use.And have a great impact for the performance of the content alloy steel of the sulphur in steel alloy or oxygen.Need to use sweetening agent or reductor when the molten alloy steel.Simultaneously, during for the needs special steel material, the wear resisting property of manganese alloy steel and high strength are widely used.Therefore, can play the effect of reductor and sweetening agent again, be the primary selection of refining manganese alloy steel using manganeseirom to be raw material in preparing the process of manganese alloy steel.
But the phosphorus in the existing manganeseirom that uses and the too high levels of carbon in deoxidation and desulfurization, have increased the content of phosphorus and carbon on the contrary, affect the performance of steel alloy.
Summary of the invention
The purpose of this invention is to provide a kind of manganeseirom of low-phosphorous, low-carbon (LC), can effectively overcome phosphorus and the too high problem of carbon content in existing manganeseirom.
The present invention is achieved by the following technical solutions:
A kind of manganeseirom, its composition includes by weight percentage, the manganese of 50-70%, the silicon of 3-5%, the carbon lower than 1.0%, the phosphorus lower than 0.1%, the sulphur lower than 0.02% is no more than other impurity of 2%, and surplus is iron.
The preparation method of described manganeseirom is:
Select percentage composition by weight to calculate carbon containing lower than 1.0% scrap steel, adding the calcium that accounts for steel weight 13-15% is dephosphorization agent, and wherein, calcium is that in dephosphorization agent, the silicon weight content is 30-35%; At above-mentioned raw materials all after fusing, remove the gred after adding the slag supplying agent residue adjustment, then add successively manganese to refine, then tapping casting becomes ingot.
The beneficial effect that the present invention compares with prior art is:
The phosphorus of resulting manganeseirom and carbon content have solved phosphorus and the too high problem of carbon content in existing manganeseirom lower than the requirement of steel.
Embodiment
Below by specific embodiment, technical scheme of the present invention is described, following examples are just in order to illustrate the present invention rather than to limit scope of the present invention.
A kind of manganeseirom, its composition includes by weight percentage, the manganese of 50-70%, the silicon of 3-5%, the carbon lower than 1.0%, the phosphorus lower than 0.1%, the sulphur lower than 0.02% is no more than other impurity of 2%, and surplus is iron.
The preparation method of described manganeseirom is:
Select percentage composition by weight to calculate carbon containing lower than 1.0% scrap steel, adding the calcium that accounts for steel weight 13-15% is dephosphorization agent, and wherein, calcium is that in dephosphorization agent, the silicon weight content is 30-35%; After above-mentioned raw materials all melts, add the slag supplying agent slag making, add again the deslagging agent slagging-off after slag making is complete, keep furnace temperature at 1350 ± 30 ℃, then add successively manganese to refine, then tapping casting becomes ingot.
Select percentage composition by weight to calculate carbon containing lower than 54 kilograms of 1.0% scrap steels, adding the calcium that accounts for steel weight 13-15% is 9 kilograms of dephosphorization agents, and wherein, calcium is that in dephosphorization agent, the silicon weight content is 35%; After above-mentioned raw materials all melts, add 1.5 kilograms of Fluorspar Powders as the slag supplying agent slag making, add again 0.5 kilogram of ferric oxide deslagging agent slagging-off after slag making is complete, keep furnace temperature at 1350 ± 30 ℃, add 79 kilograms, the manganese of weight content 99.5% to refine, then tapping casting becomes ingot again.Later stage can be carried out as required fragmentation and be reached the operations such as refining.
Above embodiment has illustrated technical scheme of the present invention, it will be appreciated by those skilled in the art that and can is out of shape or is equal to replacement by above-mentioned technical scheme, all can access other embodiments of the invention.
