Abstract

The invention discloses a steel-smelting boron composite solvent, which comprises the following parts: 1) 10-40% 200-order raw bauxite powder, 60-90% 200-order boron tail ore; 2) 5-25% 200-order raw bauxite powder, 30-50% 200-order boron tail ore and 30-60% 200-order boron mud.

Description

Boron composite fluxing agent for making steel
Technical field
The present invention relates to the ferrous metallurgy boron composite fluxing agent for making steel.
Background technology
For a long time, China generally uses fluorite or synthetic calcium aluminate etc. to carry out slag making in steelmaking process and changes slag.Though fluorite is favourable to slag making and change slag, it at high temperature decomposes easily, makes F-content overproof in the water and air, causes the severe contamination of air and recirculated water; There is not pollution problem in calcium aluminates etc., but production cost is higher, and influence is applied.
There are abundant discarded boron mine tailing or boron mud resource in Liaoning Province, utilizes discarded boron mine tailing or boron mud to be raw material, makes boron composite fluxing agent for making steel, is the big event that the applicant studies.
Summary of the invention
The purpose of this invention is to provide a kind of boron composite fluxing agent for making steel, is to utilize discarded boron mine tailing or boron mud to be main raw material, adds the alumina of different ratios, determines the flux prescription that fusing point is not higher than 1400 ℃.
Boron composite fluxing agent for making steel, it is characterized in that this flux be by following compositions by weight ratio make:
1) 200 purpose raw bauxite powder: 10-40 part;
200 purpose boron mine tailings: 60-90 part;
Technical process is:
Described raw material weight part ratio batching on request, pressure ball, drying, sintering goes out finished product.
The finished product technical performance index is:
Flux 1)
Chemical ingredients/%
B 2O 3 5~8
Al 20 3 10~35
Size composition/mm 5~30
Temperature of fusion/℃ about 1300
Above flux:
The first, fusing point own is low, is heated under the steel-making condition and promptly changes;
The second, good with the slag reactivity, the resultant fusing point is also low, easily flows and sprawls.
The present invention's beneficial effect compared with prior art is:
This invention product replaces fluorite and calcium aluminate, and existing flux fluorite pollutes, calcium aluminate cost height to solving, take up an area of contaminate environment to solving boron mine tailing and boron mud, do mineral resources comprehensive utilization well, promote recycling economy and develop in a healthy way at a high speed, reduce steel-making cost, all significant.
