Abstract
The present invention is a kind of steelmaking slagging material, and described slag making materials comprises the material of following weight part: lime 65-75, Fluorspar Powder 9-13, aluminum oxide 16-20, rhombspar 6-8 and impurity.The lime contained in slag making materials of the present invention is slag making in STEELMAKING PRODUCTION, the requisite composition such as modification, be conducive to the basicity improving slag, ensure that good deoxidation effect, aluminum oxide can adjust the fusing point of slag system, along with the increase of aluminum oxide, the viscosity of slag will increase, content controls between 16-20, good slag making effect can be obtained, and Fluorspar Powder add the degree that can reduce dry slag, prevent ladle dry slag, Fluorspar Powder can also accelerate the dissolving of lime, improve the dynamic property of slag, the magnesium oxide contained in rhombspar can extend the life-span of refractory materials, Fluorspar Powder in this slag making materials and aluminum oxide are the slag charge after esr uses, used Fluorspar Powder and aluminum oxide are used as steelmaking slagging material, our experiments show that, steelmaking slagging better effects if, and serve the effect of turning waste into wealth.
Description
Technical field
The present invention relates to a kind of material, especially a kind of steelmaking slagging material.
Background technology
At present, the specification of quality of user to steel is more and more higher, not only require that inclusion content of steel is few, be mingled with granularity also little, the object of esr is purified metals and obtains the steel ingot of pure homogeneous microstructure densification, main containing Fluorspar Powder and aluminum oxide in the slag charge that esr uses, and steelmaking slagging material, be generally use lime and fluorite in the market, all can not get good utilization for the slag charge Fluorspar Powder of esr and aluminum oxide, waste material is many.
Summary of the invention
In order to solve the problem, the invention provides a kind of used material and carry out steelmaking slagging, steelmaking slagging is effective.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of steelmaking slagging material, and described slag making materials comprises the material of following weight part: lime 65-75, Fluorspar Powder 9-13, aluminum oxide 16-20, rhombspar 6-8 and a small amount of inevitably impurity.
A kind of steelmaking slagging material of the present invention, described slag making materials comprises the material of following weight part: lime 65, Fluorspar Powder 13, aluminum oxide 20, rhombspar 8 and a small amount of inevitably impurity.
A kind of steelmaking slagging material of the present invention, described slag making materials comprises the material of following weight part: lime 70, Fluorspar Powder 12, aluminum oxide 18, rhombspar 7 and a small amount of inevitably impurity.
A kind of steelmaking slagging material of the present invention, described slag making materials comprises the material of following weight part: lime 75, Fluorspar Powder 9, aluminum oxide 16, rhombspar 6 and a small amount of inevitably impurity.
The invention has the beneficial effects as follows: the lime contained in slag making materials of the present invention is slag making in STEELMAKING PRODUCTION, the requisite composition such as modification, be conducive to the basicity improving slag, also slag system deoxidation is conducive to, ensure that good deoxidation effect, but the too high levels of lime, the viscosity of slag can be made also to increase, aluminum oxide can adjust the fusing point of slag system, along with the increase of aluminum oxide, the viscosity of slag will increase, the content of aluminum oxide controls between 16-20, good slag making effect can be obtained, and Fluorspar Powder add the degree that can reduce dry slag, prevent ladle dry slag, Fluorspar Powder can also accelerate the dissolving of lime, improve the dynamic property of slag, fluxing action is fast, the magnesium oxide contained in rhombspar can extend the life-span of refractory materials, Fluorspar Powder in this slag making materials and aluminum oxide are the slag charge after esr uses, used Fluorspar Powder and aluminum oxide are used as steelmaking slagging material, our experiments show that, steelmaking slagging better effects if, and serve the effect of turning waste into wealth.
Slag making materials of the present invention, effectively can remove the harmful element p and s in steel, and protection molten steel, improves the recovery rate of metal, reach the requirement of steel grade.
