Abstract
The invention relates to a refractory material, particularly to an environment-friendly induction melting furnace lining refractory material. The furnace lining refractory material is prepared by: taking quartz sand as the main raw material, then adding fused crystal powder, an admixture and a sintering agent and conducting mixing, and then employing mechanical casting or melting. The refractory material comprises the following raw materials by weight: 10-12 parts of 6-8mm quartz sand particles, 12-15 parts of 9-12mm quartz sand particles, 20-26 parts of 0.05-0.06mm quartz sand particles, 5-6 parts of 45-48micrometer quartz sand powder, 8-15 parts of fused crystal fine powder and micro-powder, 3-5 parts of silicon carbide, 0.2-0.3 part of chromium concentrate, and 0.3-0.5 part of the admixture. Quartz sand particles with different particle sizes are compounded together, the manufacturing cost of the material is lowered (the overall cost of the material can be saved by about 10%), at the same time the fire resistance and service life of the product are improved, and the furnace life can be at least doubled.
Description
Technical field
The present invention relates to a kind of refractory material, particularly to a kind of environment-friendly type induction melting fire proof material of furnace lining.
Background technology
At present, induction melting furnace sand mold furnace lining, all pursue ideal service life, first it is considered that use the sand material of high-quality, but it is the most relatively costly, existing various fire proof material of furnace lining all cannot not only meet the requirement lasting a long time but also meeting relative inexpensiveness, it is therefore desirable to improves this material.
Summary of the invention
The present invention provide a kind of service life length, recoverable and the environment-friendly type induction melting fire proof material of furnace lining of relative inexpensiveness.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of environment-friendly type induction melting fire proof material of furnace lining, described refractory material is with quartz sand as primary raw material, add electric smelting crystal powder, additive and agglutinant and carry out mix and blend, using the refractory material that the mode of machine casting or melting is made, this material includes following raw material by weight:
6 ~ 8mm quartz sand particle of 10 ~ 12 parts, 9 ~ 12mm quartz sand particle of 12 ~ 15 parts, 0.05 ~ 0.06mm quartz sand particle of 20 ~ 26 parts, 45 ~ 48 μm quartz sand powders of 5 ~ 6 parts, the electric smelting crystal fine powder of 8 ~ 15 parts and micropowder, the carborundum of 3 ~ 5 parts, the fine chrome mine of 0.2 ~ 0.3 part, the additive of 0.3 ~ 0.5 part.Inventor it has been investigated that, add the fine chrome mine of trace, can improve the erosion performance of this refractory material, improve the high temperature folding strength (400 DEG C × 0.5h, meansigma methods is 7.86 MPa) of material.
As preferably, described additive be in boric acid, boric anhydride, solid water glass one or both and above arbitrarily than mixture.
As preferably, the granular size of described electric smelting crystal fine powder and micropowder is respectively below 400 mesh-450 mesh, 0.8 μm, and the mass ratio of fine powder and micropowder is 3:1.Electric smelting crystal powder be also classified into the raw material of two particle diameters as component with the use of, the fire resistance of product is played the function that forward promotes by this.
The invention has the beneficial effects as follows: this refractory material is made through the mode of machine casting or melting, the material melting point obtained is higher, more than 1800 DEG C, the quartz sand particle of different-grain diameter is combined with each other, reduce the manufacturing cost (this all materials cost-saved about 10%) of this material, through compounding with the effective of other components, improve fire resistance and the service life of product, furnace life can be enhanced about more than once.Meanwhile, can make, by after mechanical activation comminution, the equipment liner that other fire resistance relative requirement are the highest after this materials'use.
