Abstract
The invention provides a refractory brick and a fabricating method thereof. The refractory brick is made of the following materials: Mica powder, Calcium powder, silicon dioxide powder, aluminium chloride, ceramic powder, kaolinite, talcum powder, organic bentonite and bergmeal. The fabricating method comprises the following steps: first, uniformly mixing all the materials; second, placing the mixed powders into a mould and firing under the pressure of 100-200 MPa and at the temperature of 100-200 DEG C for 2-3 hours; and third, demoulding. The refractory brick fabricated by the invention is large in both unit size and high in density, has good thermal shock resistance, and is small in environmental pollution, low in cost and simple in production condition and equipment.
Description
Technical field
The invention belongs to the refractory brick field, particularly a kind of refractory brick and preparation method thereof.
Background technology
Refractory brick generally is divided into two kinds, i.e. amorphous refractory and typing refractory materials.Amorphous refractory: also be mould material, by multiple aggregate or gather materials and the mixing powdery material that forms of one or more bonding agents, must stir with one or more liquid cooperations during use, have stronger flowability.The typing refractory materials: general refractory brick processed, its shape have the standard rule, also can build when cutting as required and process temporarily.
But present refractory brick exists unit volume little usually, and therefore the situation that density is little, thermal shock resistance is bad is sought after a kind of refractory brick that can solve above shortcoming.
Summary of the invention
An object of the present invention is to provide a kind of refractory brick, another object of the present invention provides its making method, and this refractory brick unit volume is large, and density is large, and with the refractory brick that present method is made, thermal shock resistance is good.
The technical scheme that adopts is:
A kind of refractory brick comprises mica powder, calcium stone flour, silicon dioxide powder, aluminum chloride, ceramics powder, kaolin, talcum powder, organobentonite and diatomite.
