Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of impregnation treatment solution for refractory materials and carbon materials, which solves the problem that there are many organic resin impregnation solutions in the prior art, and there are many single-component impregnation solutions, which are not ideal for high-temperature use materials. Insufficient problems such as high efficiency and 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 improve the structure. dense

Embodiment 1

[0017] Example 1: The composition of the immersion solution is (weight percentage): SiO 2 25%; Al 2 O 3 12%; P 2 O 5 13%; B 2 O 3 3%; H 2 O 57%. 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 component amount in the above-mentioned materials.

[0018] According to the composition ratio, prepare the solution, put the carbon roller products to be dipped into a special container, vacuum, add the dipping 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.

[0019] 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 treatment. The pe...

[0020] Example 2: The composition of the dipping solution is (weight percentage): SiO 2 36%; Al 2 O 3 10%; P 2 O 5 6%; B 2 O 3 1%; H 2 O 57%. In the formula, silica sol, aluminum sol, and aluminum phosphate solution are combined with boric acid.

[0021] According to the composition ratio, prepare the solution, put the carbon electrode product 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. After treatment, the oxidation resistance of the material can be improved. The test results are shown in the attached table.

Embodiment 3

[0022] Example 3: The composition of the dipping solution is (weight percentage): SiO 2 28%; Al 2 O 3 5%; B 2 O 3 1.5%; Na 2 O+K 2 O 0.5%; H 2 O 75%. In the formula, silica sol and aluminum solution are combined with sodium borate and sodium potassium silicate.

[0023] According to the composition ratio, configure the solution, put the high alumina brick 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. Some products need to be fired again, according to the firing temperature system.

[0024] From the experiments conducted, it can be seen that the present invention can reduce the porosity of the material, increase its density and strength, and improve the oxidation resistance. The performance results are shown in the attached table.

Abstract

The inorganic sol for dipping refractory material and carbon material consists of SiO2 3-50 wt%, Al2O3 2-50 wt%, B2O3 0.01-50 wt% and H2O2 5-70 wt%. It has nanometer level grain size after drying, high flowability, automatic solidification, and no bursting and cracking in drying and sintering. The dipped refractory material may be used after being dried in normal temperature, and at high temperature, one stuffing phase combined stably with inorganic material may be formed to raise the strength of the refractory material. The dipped carbon material has improved antioxidant performance and antiwear performance.

Description

Technical field [0001] The invention relates to an impregnation solution for refractory materials or carbon materials, in particular to an impregnation treatment technology for refractory materials and carbon 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 ratio 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, improve the strength, and improve certain performance indicators a...
