Abstract
The invention relates to a metal alloy material and concretely relates to an aluminum-silicon-manganese alloy. The aluminum-silicon-manganese alloy comprises, by weight, 2-18% of Al, 8-15% of Si, less than or equal to 1.6% of C, less than or equal to 0.02% of S, less than or equal to 0.18% of P and the balance Mn. Compared with the traditional aluminum-silicon-manganese alloy, the aluminum-silicon-manganese alloy provided by the invention has higher specific gravity even reaching to 5-5.5g/cm<3>, can penetrate a slag-liquid surface to reach to a deep position in molten steel and can realize full utilization of valuable elements. The aluminum-silicon-manganese alloy has low impurity content. After decarburization, the aluminum-silicon-manganese alloy has less content of impurities such as carbon, phosphor and sulfur so that secondary pollution on molten steel is reduced. The aluminum-silicon-manganese alloy reduces a steel-making cost and saves a lot of an aluminum resource.
Description
Technical field
The present invention relates to a kind of metal alloy compositions, specifically relate to a kind of Al-Si-Mn alloy.
Background technology
In prior art, containing manganese alloy steel series product, the scope of application is wider.But existing Al-Si-Mn alloy ubiquity proportion is lower, impurity is higher, manufacturing process is complicated, the more high defect of manufacturing cost.
Summary of the invention
The object of the present invention is to provide a kind of Al-Si-Mn alloy, can significantly improve alloy proportion, reduce the impurity in alloy and reduce the secondary pollution of molten steel, reduce steel-making cost and save bauxite resource.
To achieve these goals, the technical solution used in the present invention is as follows:
Al-Si-Mn alloy, is characterized in that, the weight percent of described Al-Si-Mn alloy is:
Al 2～18％；
Si 8～15％；
C ≤1.6％；
S ≤0.02％；
P ≤0.18％；
Surplus is Mn.
Further preferably, the weight percent of described Al-Si-Mn alloy is:
Al 7～12％；
Si 11～15％；
C ≤1.4％；
S ≤0.01％；
P ≤0.10％；
Surplus is Mn.
Al-Si-Mn alloy of the present invention, proportion has by a relatively large margin and promotes compared with conventional aluminum silicomanganese, can reach 5～5.5 grams every cubic centimetre, thereby can penetrate slag liquid level, gos deep into, in molten steel, taking full advantage of valuable element.In addition, because impurity is lower, alloy is after decarburization, and the impurity such as institute's carbon containing phosphorus sulphur all decrease, and have reduced the secondary pollution of molten steel.Meanwhile, reduce the cost of making steel, saved a large amount of bauxite resources.
