Abstract
The present invention proposes a kind of neutral refractory, is made from the following raw materials in parts by weight：4 10 parts of carborundum, 15 parts of aluminium oxide, 15 parts of chromium oxide, 15 parts of zirconium oxide, 26 parts of graphite powder, 4 10 parts of clay, 59 parts of tar.The neutral refractory coefficient of expansion is extremely low, light weight, thermal conductivity are high, from any acid erosion, do not react with acid-base property slag.
Description
Technical field
The present invention relates to fire resisting material field, and in particular to a kind of neutral refractory.
Background technology
It is believed that acid slag, caustic slag, flux and other refractory materials chemistry can be preferably resisted at high temperature
The refractory material of erosion is referred to as neutral refractory.Its key component has the trivalent oxygen such as carbon, carborundum, aluminium oxide, chromium oxide
Compound, Al2O3C Bricks developed in recent years, zirconium carbon brick, aluminum oxide-silicon carbide-carbon brick, silicon nitride combined silicon carbide brick etc.,
Belong to neutral refractory.Neutral refractory is generally used for furnace bottom, cupola well, stove the bottom position of high temperature stove, at present market
On neutral refractory materials price it is high, small producer cannot be used widely, the refractory materials of other properties is again unstable
It is fixed, it is easy to other substance reactions in stove.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of neutral refractory to solve refractory material presence on the market
Various shortcomings.
The object of the invention to solve the technical problems is realized using following technical scheme：
A kind of neutral refractory, is made from the following raw materials in parts by weight：4-10 parts of carborundum, 1-5 parts of aluminium oxide, oxidation
1-5 parts of chromium, 1-5 parts of zirconium oxide, 2-6 parts of graphite powder, 4-10 parts of clay, 5-9 parts of tar, 0.5-2.5 parts of water-reducing agent.
Preferably, the water-reducing agent is aluminous cement.
Preferably, also it is made from the following raw materials in parts by weight：4 parts of carborundum, 1 part of aluminium oxide, 1 part of chromium oxide, zirconium oxide 1
Part, 2 parts of graphite powder, 10 parts of clay, 5 parts of tar, 0.5 part of water-reducing agent.
Preferably, also it is made from the following raw materials in parts by weight：10 parts of carborundum, 5 parts of aluminium oxide, 5 parts of chromium oxide, zirconium oxide
5 parts, 6 parts of graphite powder, 5 parts of clay, 9 parts of tar, 2.5 parts of water-reducing agent.
A kind of neutral refractory coefficient of expansion proposed by the present invention is extremely low, light weight, thermal conductivity are high, from any acidity
Corrode, do not react with acid-base property slag.
