Abstract

The present invention relates to a refractory material. The refractory material consists of high- alumina aggregate, fine high- alumina powder, clay powder, SiC, corundum powder, inorganic high- temperature DCE binder, and alumina cement or aluminium phosphate cement as coagulation accelerator. It is prepared by mixing high-alumina aggregate, fine high-alumina powder, clay powder, SiC and corundum powder crushed to specified sizes through stirring and adding the coagulation accelerator and the binder while stirring. The present invention has high strength, refractoriness, refractoriness under load and long-term use temperature, so that it is suitable for building various high- temperature kilns and furnaces.

Description

Inorganic combined high-strength refractory deposit material and preparation method thereof
The present invention relates to a kind of refractory materials, specifically, relate to the good refractory castable of a kind of hot strength, and relate to its preparation method.
At present, unshape refractory is in China's widespread use, typical material has luminite cement heat resistance concrete, clay fire resistant pouring material, the high temperature resistant mould material of PA-80 glue, low cement and non-cement high alumina castable etc., because its hot strength and use temperature are low, directly have influence on the work-ing life of industrial furnace high-temperature burner hearth.
The object of the present invention is to provide a kind of inorganic combined high-strength refractory deposit material and preparation method thereof.
The object of the present invention is achieved like this:
Refractory castable of the present invention is by bauxites aggregate, high alumina fine powder, clay powder, silicon carbide, lapis amiridis, as the DCE inorganic high-temp wedding agent of wedding agent, and forms as the alumine cement or the aluminum phosphate cement of setting accelerator.Prescription that it is concrete and granularity are (weight %): bauxites aggregate: 5～10mm 22～28%, bauxites aggregate: 1～5mm 30～38%, high alumina fine powder :≤0.202mm 18～22%, clay powder: 0.184～0.202mm1～7%, silicon carbide: 0.184～0.202mm 3～8%, lapis amiridis: 0.184～0.202mm1～5%, DCE inorganic high-temp wedding agent: 4～6%, in alumine cement or the aluminum phosphate cement any: 3～4%.
Above-mentioned alumine cement or aluminum phosphate cement should be selected 525# or 625# for use.
Refractory casting material manufacturing technique of the present invention is as follows:
Bauxites aggregate, high alumina fine powder, clay powder, silicon carbide and the lapis amiridis of above-mentioned granularity will be crushed to, in stirrer, be stirred to together and mix, after adding alumine cement or aluminum phosphate cement continue to stir, add again DCE inorganic high-temp wedding agent and suitable quantity of water in stirrer again brute force stir casting then.
The technical indicator that refractory castable of the present invention reached is listed in table 1.
