Abstract
The invention relates to Periclase-olivine light thermal-insulated fireproof materials and method for preparation, which comprises mixing 20-80% magnesite powder, 0-50 wt% of magnesium oxide powder, 10-30% of silicon oxide powder, 0-15% of combustible powder, 0-3% of anchoring agent, and 4-10% of water, mixing homogeneously, press forming, drying the formed blank 4-24 hours at 110 deg. C, then burning at 1300-1500 deg. C, thermally insulating 1-8 hours.
Description
One, technical field
The invention belongs to light thermal insulation fire-resistant material field.Relate in particular to the production method of a kind of periclasite-peridotites light thermal insulation fire-resistant material.
Two, background technology
Existing light thermal insulation fire-resistant material mostly is aluminium-silicon based material, and main chemical compositions is Al
2O
3With SiO
2, main thing is corundum, mullite, quartzy thing phase and glassy phase mutually.Along with the raising that steel quality, kind are required, more and more higher to the purity requirement of steel.Basic refractory is considered to a kind of desirable refractory materials that can satisfy the Clean Steel production requirement.In the ordinary course of things, basic refractory as magnesia brick, directly as the furnace lining material that directly contacts with molten steel etc., need be provided with one deck lagging material at its skin.But present lagging material mostly belongs to Al
2O
3-SiO
2Based material (Wang Weibang. fire-proof material technology. metallurgical industry press, 2003), it is acidity or neutral material, at high temperature easy and basic material reacts, and produces low melt-phase, influences work-ing life.Have only the alkaline light heat insulation material of use, could mate with basic refractory, but still not have alkaline light heat insulation material technology at present.
Another of the applicant is entitled as the application for a patent for invention of " a kind of magnesium-aluminium light heat insulation material and preparation method thereof ", and the product main chemical compositions of being produced is MgO, Al
2O
3According to the difference of their proportionings, the principal crystalline phase of product is periclasite-spinel, spinel or corundum-spinel.They can with magnesite refractory, high alumina refractory, or spinel refractory directly contact at high temperature but can not at high temperature directly contact with siliceous refractory [material.
Three, summary of the invention
The purpose of this invention is to provide a kind ofly at high temperature not only can contact with magnesite refractory, but also can contact with siliceous refractory [material, even air hole distribution, intensity height, be the light thermal insulation fire-resistant material and the production method thereof of principal crystalline phase with periclasite and peridotites.
For achieving the above object, the technical solution used in the present invention is: by weight 20～80% magnesite breeze, 0～50% light-magnesite powder, 10～30% silica powder, 0～15% burnt lost article powder are mixed, add 2～10% water and 0～3% wedding agent and stir, burn till, be incubated after repressed moulding, the drying.
Wherein, can burn one or both and two or more mixture powder in lost article powder or sawdust, coal dust, coke powder, the poly-light ball, the grain diameter that can burn the lost article powder is less than 200 μ m; The grain diameter of raw material magnesite breeze, light-magnesite powder, silica powder is less than 88 μ m; Wedding agent is dextrin or polyvinyl alcohol.
With the compression moulding behind the mixing of above-mentioned batching, the base substrate after the moulding 110 ℃ dry 4～24 hours down, under 1300 ℃～1500 ℃ temperature, burn till then, soaking time is 1～8 hour.Compression moulding can also can manual ramming with mechanical compaction.
Owing to adopt such scheme, main chemical compositions is MgO and SiO in the middle of the resulting product of the present invention
2, main crystalline phase is periclasite, peridotites, it not only can at high temperature directly contact with magnesite refractory, can also at high temperature directly contact with siliceous refractory [material.Periclasite content in prepared periclasite-peridotites light thermal insulation fire-resistant material is 10～90%, and apparent porosity has even air hole distribution, advantages of high strength 30～80%.
