Description
Technical field
The invention belongs to fire resisting material field, and in particular to a kind of castable refractory and preparation method.
Background technology
Refractory material 90% after China uses is discarded and buried as industrial refuse, and remaining 10% has only obtained coarse
Utilize, so not only consume transport and processing cost, or to national resources, the waste of human and material resources.
The content of the invention
Goal of the invention：The purpose of the present invention is to solve the shortcomings of the prior art, there is provided a kind of castable refractory.
Preparation method another object of the present invention is to provide above-mentioned castable refractory.
Technical scheme：In order to reach foregoing invention purpose, the present invention is specifically achieved like this：A kind of refractory casting
Material, including following parts by weight component, 50 ~ 80 parts of ceramic particle, 5 ~ 10 parts of mullite, 3 ~ 5 parts of silicon powder, carborundum 5 ~ 10
1 ~ 5 part of part and silicon nitride.
Wherein, the particle diameter of the ceramic particle is less than 3mm.
Wherein, the particle diameter of the mullite is less than 5mm.
A kind of preparation method of castable refractory, by formula measure each raw material add rotator type kneading machine uniformly mixing 20 ~
30 minutes, mixed material is then poured into model cast sizing, rear kiln-firing is dried at room temperature.
Beneficial effect：The present invention compared with conventional art, simple production process, moderate cost, and performance is good, surely
Qualitative good, corrosion resistance is excellent, slag resistance and high intensity are high, long service life, greatly reduces production cost, reduces comprehensive energy
Consumption.
