Problems solved by technology

[0005] The object of the present invention is to provide a refractory inorganic composite impregnation treatment solution, which solves the problem that there are many organic resin impregnation solutions in the prior art, and there are many single-component impregnation solutions. Insufficient problems such as low service life, through the inorganic composite impregnation solution, can form a material that can be densely sintered at high temperature in the impregnated object, improve the wear resistance of the material, reduce the porosity in the material, and make the structure compact

Embodiment 1

[0012] Example 1: The composition of the dipping solution is (weight percentage) SiO 2 25%; A1 2 O 3 20%; B 2 O 3 15%; Cr 2 O 3 15%; H 2 O25%. . In the formula, silica sol, aluminum dihydrogen phosphate and aluminum phosphate solution are combined with boric acid for compound preparation, and the proportioning amount is the effective ingredient amount in the above-mentioned materials.

[0013] According to the composition ratio, prepare the solution, put the carbon roller products to be impregnated into a special container, vacuum, add the impregnation solution, after a certain period of time, take it out, bake and dry, and then put it into use. If some products need to be fired again, follow the firing temperature system.

[0014] From the experiments that have been carried out, it can be seen that the dipping solution for refractory materials and carbon products of the present invention can reduce the porosity of the carbon roller material and increase its density through treatm...

Abstract

A refractory material inorganic composite dipping treatment solution comprises 5-45wt% of SiO2, 5-45wt% of Al2O3, 1-30wt% of B2O3, 10-30wt% of Cr2O3, and 20-60wt% of H2O. The solution is an inorganic material sol, and the granularity of the dried sol is nanometer level; the sol has good fluidity; and the sol automatically solidifies after a certain time, and does not explode or crack in the drying and sintering process. A product dipped in the high-fireproof phase sol can be used after being dried at normal temperature, and can form a stable inorganic material at high temperature, which can be combined with a filling phase, so the dipped refractory material product has increased strength and a compact structure; and the oxidation resistance and the wear resistance of a carbon product are improved. The solution has the advantages of easy operation, obstruction of pores, increase of the density and the strength of the material, improvement of the oxidation resistance and the thermodestruction resistance of the material, and service life prolongation.

Description

Technical field [0001] The invention relates to the technical field of refractory materials, in particular to an inorganic composite impregnation treatment solution for refractory materials. Background technique [0002] Functional refractories and certain carbon products are the key factors restricting on-site production in the metallurgical industry, such as refractory materials for RH, nozzles, stoppers, refractory rollers, rods, bricks in special parts, special-shaped pipe fittings, carbon rollers, electrodes , The performance and structure of these materials determine the length of their service life, and it is difficult to achieve the desired effect through the proportioning and molding process. Using the impregnation method, the gas in the refractory or carbon products can be drawn out by vacuuming, and the sol can be penetrated into it, which can block the pores, compact the structure, increase the strength, and improve certain performance indicators and performance.
