Abstract
The invention relates to a preparation method of a manganese-iron alloy material. The manganese-iron alloy material comprises the following components in percentage by weight: 44-48% of manganese, 3-5% of silicon, 0.1-0.3% of niobium, 0.3-0.5% of aluminum, less than 1.0% of carbon, less than 0.1% of phosphorus, less than 0.02% of sulfur, less than or equal to 2% of other impurities and the balance of iron. The phosphorus and carbon contents of the obtained manganese-iron alloy material are lower than the requirements of a steel material, and the problem of overhigh contents of phosphorus and carbon in an existing manganese-iron alloy is solved.
Description
Technical field
The invention belongs to metal material field, refer to a kind of for the manganeseirom material preparation method as sweetening agent or reductor especially.
Background technology
Along with the development of Iron And Steel Industry, the steel alloy of many high quality, high-quality is developed use.And the performance of the content alloy steel of the sulphur in steel alloy or oxygen is had a great impact.Need when molten alloy steel to use sweetening agent or reductor.Meanwhile, during for needs special steel material, the wear resisting property of manganese alloy steel and high strength, be widely used.Therefore, preparing in the process of manganese alloy steel at use manganeseirom and be the effect that raw material can play again reductor and sweetening agent, is the primary selection of refining manganese alloy steel.
But the phosphorus in the existing manganeseirom used and the too high levels of carbon, while deoxidation and desulfurization, add the content of phosphorus and carbon on the contrary, affect the performance of steel alloy.
Summary of the invention
The object of this invention is to provide a kind of manganeseirom of low-phosphorous, low-carbon (LC), effectively can overcome the phosphorus in existing manganeseirom and the too high problem of carbon content.
The present invention is achieved by the following technical solutions:
A kind of manganeseirom material preparation method, comprises the following steps:
1) prepare burden;
2) select the carbon containing of percentage composition calculating by weight in batching lower than the steel of 1.0%, add the calcium system dephosphorization agent accounting for steel weight 13-15%, wherein, in calcium system dephosphorization agent, silicon weight content is 30-35%;
3) melting, after above-mentioned raw materials all melts, adds slag supplying agent slag making, adds deslagging agent slagging-off after slag making again, and keep furnace temperature at 1350 ± 30 DEG C, then add manganese, niobium and aluminium successively and refine, then tapping casting becomes ingot.
Described batching, its composition is by weight percentage, the manganese of 44-48%, the silicon of 3-5%, and the niobium of 0.1-0.3%, the aluminium of 0.3-0.5%, carbon lower than 1.0%, lower than the phosphorus of 0.1%, lower than the sulphur of 0.02%, be no more than other impurity of 2%, surplus is iron.
Described niobium adds with ferrocolumbium.
The present invention's beneficial effect is compared with the existing technology:
The phosphorus of the manganeseirom 1, obtained and carbon content, lower than the requirement of steel, solve the phosphorus in existing manganeseirom and the too high problem of carbon content.
2, by adding niobium in manganeseirom, the removal efficiency to p and s in alloy can be improved, and, by adding aluminium in the alloy, can make in fusion process, the impurity in each composition floats on above liquid with the form of slag, improves the quality of manganeseirom.
