The front surface layer of the brick is a far infrared refractory material layer, the back of the brick is covered with a light body refractory material layer, the heavy body refractory material layer and the light body refractory material layer of the matrix are provided with hollow notches or holes, and the composite refractory material brick has the performances of high temperature resistance, scouring resistance, high efficiency and energy conservation.
Description
Heavy and light far infrared fire proof material brick is combined into by multilayer different structure material, is mainly used in the kiln of industry or the internal layer of stove.
Existing fire proof material brick, especially for the fire proof material brick of industry kiln or stove internal layer, common aluminum silicate fiber brick high insulating effect, but because of its intensity is low, anti-collision not, work-ing life is short, and cost an arm and a leg, non-refractory.Having higher resistant to elevated temperatures heavy fire proof material brick integral body all is to adopt resistant to elevated temperatures heavy refractory materials to make, though its high temperature resistant, anti-collision, its thermal capacitance is bigger, the thermal conductivity height makes that the heat absorption of kiln or stove internal layer is big, and heat insulation effect is poor, heat lost by radiation is big, wastes a large amount of energy.
The purpose of this utility model is to provide that a kind of thermal capacitance is little, good heat insulation and energy-conservation heavy and light far infrared fire proof material brick.
The fire resistant materials layer of attaching most importance in the middle part of the outer fire proof material brick of heavy and light of the present utility model flood far away.Its constructional feature be heavy refractory masses one side compound the lightweight refractory layer, opposite side compound the far infrared refractory masses.Like this, the lateral far infrared refractory masses of heavy and light far infrared fire proof material brick has higher high thermal resistance (generally more than 1500 ℃) as the front, and has higher radiation coefficient, reduces heat absorption.The far infrared refractory masses again with the heavy refractory materials as matrix, have higher intensity.And the high thermal resistance of heavy refractory materials can slightly reduce.Lightweight refractory layer thermal conductivity as the heavy and light far infrared fire proof material brick back side is low, makes heavy and light far infrared fire proof material brick thermal resistance increase, and improves heat retaining property, reduces outwards heat radiation.The lightweight refractory layer is a matrix with the heavy refractory masses, has improved the intensity of lightweight refractory layer, and the high thermal resistance of lightweight refractory layer can reduce the cost of minimizing brick.
In order further to reduce the thermal capacity of brick, improve heat insulation effect, the heavy refractory masses of heavy and light far infrared fire proof material brick of the present utility model, lightweight refractory layer have the hollow or hollow hole of notch, make it have the hollow or hollow hole of the notch that increases thermal resistance.In order to increase the mutual combined strength bination of each layer of heavy and light far infrared fire proof material brick, bonding surface is preferably the serrated face that cooperatively interacts or uneven between heavy refractory masses and far infrared refractory masses, the lightweight refractory layer.
Preferably select following proportioning material: Al for use as the heavy refractory masses

Heavy and light far infrared fire proof material brick of the present utility model is compared with existing technology, has following advantage:
1. the far infrared refractory masses of front is positioned at the internal surface of stove or kiln, and making has very high reverberation, makes body of heater keep higher temperature, reduces the brick layer and conducts heat.The thermal capacity of whole brick reduces simultaneously, reduces heat absorption, and thermal conductivity is little, and conductive heat loss is few, has saved heat lost by radiation greatly, has reached energy-conservation effect.
2. the far infrared refractory masses and the heavy refractory masses that form stove or kiln surface of internal cavity are combined into one, and make it that very high intensity be arranged, and have better heat-resisting impact and anti-collision, have long work-ing life.
3. adopt three kinds of layers of material compound, selected the cost of material is low, particularly produces the waste material fly ash float of usefulness, makes the cost cost of brick lower.
