Abstract
The invention discloses steel being low in raw material cost. The steel comprises the following raw material components in percentage by weight: not more than 0.15% of carbon, not more than 0.022% of aluminum, not more than 0.54% of silicon, not more than 0.0137% of surplus, 1.25-1.73% of molybdenum, not more than 0.0267% of phosphorus, and the balance of iron and impurities. A converter steelmaking craft is adopted during a smelting process of the steel; during converter steelmaking, pig iron and quick lime are mixed; and air is blown into the converter, and then the converter is rotated for a reaction, thereby obtaining the steel. By adoption of the above technical scheme, the steel disclosed by the invention has the advantages the selected raw materials are easy to obtain and low in cost, so that the consumption of precious metal is greatly lowered; and meanwhile, the quality of the obtained steel is not reduced; and accordingly, the whole cost is reasonably controlled, and a lot of cost can be saved for an enterprise.
Description
Technical field
The present invention relates to Steel material field, particularly relate to the steel that a kind of cost of material is low.
Background technology
Steel is the material of carbon containing and ferrum, mostly ferrum.In the Nature, pure metallic iron is little, and the aerolite only dropped out of the clouds just is almost pure iron, and overwhelming majority ferrum is all to exist with the state of compound.Pitch-black shinny, have magnetic magnetic iron ore ferroso-ferric oxide, mauve bloodstone ferrum oxide, the limonite of brown color, the siderite ferric carbonate of black gray expandable, clinquant pyrite, is not suitable for the material as steel-making except pyrite sulfur-bearing is the highest, and remaining has the biggest application in steel-making.The cost of material that existing steel needs is high, originates the most extensive, it is impossible to enough use on a large scale.
Summary of the invention
The technical problem that present invention mainly solves is to provide the steel that a kind of cost of material is low, can meet modern's demand to steel.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the steel that a kind of cost of material is low, the material composition of described steel includes carbon, aluminum, silicon, sulfur, manganese, phosphorus, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon≤0.18%, aluminum≤0.022%, silicon≤0.54%, sulfur≤0.0137%, manganese 1.25-1.73%, phosphorus≤0.0267%, ferrum and impurity: surplus, the smelting process of described steel uses converter steelmaking process, described pneumatic steelmaking is to be mixed with quick lime by the pig iron, and blast air and rotate converter and carry out reaction and obtain steel.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.14%, aluminum 0.017%, silicon 0.37%, sulfur 0.0122%, manganese 1.54%, phosphorus 0.0234%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, the reaction temperature of described pneumatic steelmaking is 1400-1600 DEG C.
In a preferred embodiment of the present invention, described pneumatic steelmaking uses the one in side-blown converter, top-blown converter, bottom-blown converter.
