Abstract
The invention discloses a silicon-manganese-iron alloy. The silicon-manganese-iron alloy comprises the following components in percentages by weight: 22-35% of silicon, 18-65% of manganese, less than or equal to 2% of carbon, less than or equal to 0.6% of unavoidable impurities and the balance of iron. The silicon-manganese-iron alloy disclosed by the invention is lower in silicon content and higher in manganese content, so as to increase manganese content in molten steel during low-carbon steel smelting process to effectively reduce oxygen content in steel. The silicon-manganese-iron alloy is good in deoxidization effect and is capable of avoiding problems of reduced plasticity and ductility of steel caused by excessive silicon content.
Description
Technical field
The present invention relates to technical field of iron alloy, particularly relate to a kind of ferro-silico-manganese.
Background technology
In the process of converter smelting low-silicon low-carbon steel, component controlling need be carried out to molten steel, make the mass percent of each Chemical Composition in molten steel reach corresponding requirement.Silicon is reductor the most basic in steel, when smelting ordinary steel, usually adopting silicon as reductor, but can reduce plasticity and the toughness of steel because silicone content is too high, being not suitable for smelting low carbon steel.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of ferro-silico-manganese, deoxidation effect is good, can avoid the too high plasticity of reduction steel of silicone content and the problem of toughness.
The present invention adopts following technical scheme to achieve these goals:
A kind of ferro-silico-manganese, the weight percentage of its component and each component is:
Silicon 22-35%;
Manganese: 18-65%;
Carbon :≤2%;
Inevitable impurity :≤0.6%;
Iron: surplus.
Preferably, described ferro-silico-manganese, the weight percentage of its component and each component is:
Silicon 25-30%;
Manganese: 50-60%;
Carbon :≤2%;
Inevitable impurity :≤0.6%;
Iron: surplus.
Preferably, described ferro-silico-manganese is granular, and its particle diameter is within the scope of 1.5-2.5mm.
Inevitable impurity of the present invention is in preparation process, and the metallic element that can not thoroughly remove and non-metallic element, mainly refer to sulphur, phosphorus etc.
Preparation method of the present invention, first prepares master alloy silicomanganese, then melts manganese, iron, is added by silicomanganese in ferromanganese solution and also fully stirs fast, then injects cooling fast in ingot mould fast.
Compared with the prior art, beneficial effect of the present invention is as follows:
Silicone content in ferro-silico-manganese of the present invention reduces, and Fe content is higher, when smelting low carbon steel, the Fe content in molten steel can be improved, effectively can remove oxygen content in steel, deoxidation effect is good, can avoid the too high plasticity of reduction steel of silicone content and the problem of toughness simultaneously.
