Abstract
The invention discloses a silicon calcium manganese alloy. Compared with previous technology, that it reduces silicon volume in alloy rationally and increases manganese volume property is its main improvement point. Its concrete alloy content is: silicon 25-50%, calcium 10-25%, manganese 20-45%, the residue is iron. Compared with previous technology, the invention has advantages of rational alloy element proportion, high alloy density, good molten steel kinetic performance, good effect of deoxidation and desulfuration, high mental obtained ratio, and no pulverization. The invention provides an ideal alloy additive for steel refining of hard-wire product such as tyre meridian and wierrope etc. and especially to non-aluminium deoxidation refining molten steel.
Description
Technical field
The invention belongs to alloy technology.What be specifically related to is a kind of SiCaMn alloy.
Background technology
SiCaMn alloy is the typical additives of present a kind of deoxidation of molten steel desulfurization.And the SiCaMn alloy of standard contains 16-20%Ca, 14-18%Mn, and 53-59%Si, and all the other are Fe and residual impurity such as C, S, P.Obviously, existing SiCaMn alloy is the SiCaMn alloy of the low manganese of high silicon.Though the deoxidizing capacity of silicon is stronger than manganese, concerning many steel grades, be strict control to the residual quantity of silicon.If silicon and manganese are lumped together use, the deoxidation of molten steel effect then can improve greatly.This is because the product of their combined deoxidations is a manganous silicate, and the activity of silicon in the manganous silicate, is significantly less than the activity of silicon in unique product silicon-dioxide of silicon deoxidation.But the practice prompting, manganese improves the deoxidation effect of silicon, reduces along with the raising of silicone content.Thereby, to the constituent content of existing SiCaMn alloy, do scientific and reasonable allotment, under the condition of basicly stable calcium content, reduce silicone content, improve manganese content, thereby improve the complex art economic target of SiCaMn alloy, just seem very necessary.
Summary of the invention
The object of the invention is, existing SiCaMn alloy constituent content is adjusted, under the condition of basicly stable calcium content, rationally reduce silicone content, suitably improve manganese content, and a kind of deoxidation, sweetening effectiveness ideal SiCaMn alloy are provided, to overcome the deficiency of prior art.
The technical scheme that realizes purpose of the present invention is that its percentage composition (weight %) is:
Silicon 25-50;
Calcium 10-25;
Manganese 20-45;
Other unavoidable impurities summation≤0.20 such as phosphorus, sulphur;
Iron surplus
A typical percentage composition of the present invention (weight %) is:
Silicon 28-32;
Calcium 10-15;
Manganese 28-42;
Other unavoidable impurities summation≤0.20 such as phosphorus, sulphur;
Iron surplus
Another typical percentage composition (weight %) of the present invention is:
Silicon 40-50;
Calcium 12-14;
Manganese 20-28;
Other unavoidable impurities summation≤0.20 such as phosphorus, sulphur;
Iron surplus
SiCaMn alloy of the present invention, compared with the prior art, it is big to have density, deoxidation, sweetening effectiveness are good, and the molten steel dynamic performance is good, and metal is obtained characteristics such as rate height, be to smelt Hi-Stren steel, especially smelt the alloy addition of rigid line products such as tire meridian and wireline with the ideal deoxidization desulfuration of steel, simultaneously, for the al-free deoxidation liquid steel refining provides a kind of ideal alloy addition.
Embodiment
Adopting the 250KW medium-frequency induction furnace, and every stove remelting total amount is that 300Kg is an example, and the weight of its relevant furnace charge is respectively:
Calcic 30% contains the silicocalcium 150Kg of Si55%
Industrial silicon 8Kg
Electrolytic manganese 120Kg
Steel scrap 22Kg
The remelting process preparation process of SiCaMn alloy of the present invention, carry out successively according to the following steps:
1, above-mentioned furnace charge is weighed standby;
2, add steel scrap earlier;
3, treat scrap melting after, add the silicocalcium of used silicocalcium total amount 2/3;
4, treat furnace charge fusing that the 3rd step added after, add industrial silicon in batches;
5, treat furnace charge fusing that the 4th step added after, add electrolytic manganese in batches;
6, treat furnace charge fusing that the 5th step added after, be warming up to 1150 ℃, stir and remove removing dross;
7, ingot casting;
8, fragmentation.Granularity requirements is: 2mm-50mm.
According to above-described embodiment, prepared SiCaMn alloy of the present invention, its percentage composition (weight %) is:
Silicon 28%;
Calcium 14%;
Manganese 40%;
Unavoidable impurities such as phosphorus, sulphur summation＜0.12;
Iron surplus.
Use cost of the present invention is compared with the silicocalcium that uses siliceous 55% calcic 28%, can reduce 15-20% approximately under identical test conditions.Use the present invention to have tangible economic benefit.And because the present invention can efflorescence, and give the external refining of steel, created good operating environment and treatment condition.
