Refractory bricks are aluminosilicate fire refractory bricks with an AL2O3 content of 30% or more. Firebrick is a basic material for high-temperature technology and has a very close relationship with various industrial furnaces. Different kinds of refractory bricks also show different basic characteristics due to the differences in chemical mineral composition, microstructure, and production process.
PER refractory company produces high-quality refractory bricks including fire clay bricks, high alumina refractory fire bricks, silica fire bricks, magnesia fire bricks, mullite fire bricks, and insulation fire bricks, etc.

PER Refractory Manufacturing Company has many years of experience in exporting refractory bricks:
The general fireproof brick packaging is divided into two ways: wooden pallet or straw rope.
1. Wooden pallet packaging is generally 1m×1m in length and width, and the base is 15cm, so how are the refractory bricks placed in the wooden pallet?
For example, the size of the standard brick is 230 * 114 * 65mm, four trips per layer vertical 15 of + horizontal 4 = 64.
According to the 3.4kg/block of clay bricks, it can be loaded with ten to twelve layers. Each pallet is packed according to the upper limit of 2.3 tons.
2. Straw rope packaging to standard brick as an example, generally 6 pieces packed together.
Firebrick’s basic quality requirements are alumina higher than 38% (usually 42-47%) as well as low iron and low alkali metal content, these should belong to its chemical properties.
But while you understand the physical properties like the specifications of fire bricks, don’t neglect to mention the physical and chemical properties of refractory bricks. Such properties include shaped refractory bricks, high alumina fire bricks for coke ovens, etc. will have.
As fire-resistant bricks are a kind of ultra-fine silica powder material formed by the condensation of SiO2 and Si gaseous state that occurs during metallurgy of ferrosilicon alloy and industrial silicon with the rapid oxygenation in oxygen.
Foremost, the appearance of fireproof bricks is a gray and white powder, with refractories > 1600 ℃. Its capacity: 200~250kg/m3.
Second, the precision of fire-resistant bricks, fire resistant bricks in the precision of less than 1 micron accounted for more than 80%, per capita particle size in 0.1 ~ 0.3 microns, specific surface area: 20 ~ 28m2 / g. Its precision and specific surface area are about 80 ~ 10100 times that of steel, and 50 ~ 70 times that of fly ash. Its precision will be relatively higher.
Finally, the particle material state and mineral phase structure, fire-resistant bricks in the composition process, because of the process of phase change by the utility of the surface pull, constitutes a non-crystalline phase amorphous round spherical particles. And the surface layer is quite slippery, some are more than one round spherical particles stick in a case of cheerful aggregates.
It is a kind of volcanic ash object with a very, very large specific surface area and very, very high activity. The material mixed with fire bricks, a fine spherical body can play a lubricating effect.
Refractory fire-resistant bricks can be used as high-temperature construction materials and structural materials for building kilns. As well as a variety of heating equipment that undergoes various physical and chemical changes and mechanical effects at high temperatures. Such as clay bricks, high alumina bricks, silicon bricks, magnesium bricks, silicon mullite bricks, etc.
High alumina bricks: High alumina refractory brick has more than 75% Al2O3 content and high refractories. It has a good ability to resist acid and alkali erosion. It is suitable for the location of the cement kiln firing zone.
Silicon carbide bricks: It has high-temperature resistance, low thermal expansion, good wear resistance, and good thermal shock resistance, and is suitable for kiln cooling belts and outlets.
Silica Mullite Bricks: The raw material is bauxite and silicon carbide, which is made by pressing and sintering. It is suitable for the transition zone with good thermal shock resistance, high strength, and good wear resistance.
Clay bricks: It is a weakly acidic refractory material. It has good thermal stability and is suitable for a hot air furnace chamber.
PER Refractory has more than 20 years of experience in the production of refractory bricks and refractory castables. Our rich experience ensures that our products have very much refractory material price advantage and quality advantage:
“Refractoriness” refers to the refractory products in the production of the application process that can be resistant to a high-temperature degree, and not be melted function. The fire brick hydraulic press can effectively reduce the cost and save material loss.
Especially in the finished product rate has great progress, not only can make a refractory factory improve production efficiency, but also can greatly save labor costs.
The “room temperature resistance Zhuang strength” is one of the main quality indicators for the use of non-fired heat resistant fire bricks products with indefinite refractory materials.
Small porosity of fire rated products, indicating a good degree of denseness, and the quality of the brick is good.
Apparent porosity is the ratio of the volume of pores (i.e., initiation of cavitation) to the total volume of fire-proof products within the atmosphere.
Firebrick products have two concepts of compressive strength.
One is called “room temperature compressive strength”, which is defined as the ultimate compressive stress strength in the indoor laboratory, according to the unit area of the specimen that can withstand without being destroyed.
The second is called “high-temperature compressive strength”, which is defined as the ultimate compressive stress that a refractory product specimen can withstand per unit cross-sectional area without being destroyed by firing to a specified high temperature. In refractory material, these two kinds of porosity are expressed in percentage.
The use of a four-column hydraulic system, pressing brick air force average, pressure, in the refractory industry than widely used.
Especially large refractories and special refractories production field, but also play an important role.
By changing the mold of the firebrick press, and material ratios, the production of a variety of special refractory materials becomes relatively easy.
Based on no increase in investment in equipment, refractory brick hydraulic presses can achieve a multi-purpose machine, a multi-purpose machine.
Another is called “true porosity”, that is, the volume of all the pores in the refractory products (including the open and closed pores) to the total volume of the ratio.
“Normal temperature pressure strength” for general refractory products, is a measure of its impact on the furnace material, wear, and liquid slag flushing can resist one of the important indicators.
“High-temperature load softening point” refers to the fire resistant bricks for sale products in the production process, not only to resist high temperature, and to resist the slag, a variety of metal or material solutions, or processing parts of the flushing corrosion, acid-resistant bricks and withstand the pressure of the structural parts of the furnace body. Have the above function of the extreme limit called “high-temperature load softening point”.
There are also a few professional kilns on the refractory products porosity requirements should not be too small, to have the function of resistance to rapid cold and heat.
