Produce Processing 

Crushing

In this stage massive raw materials which have been stored, are ground and classified into proper sizes, making them easier to shape.

Mixing

The prescribed size of ground raw material is weighed and mixed into a designated amount of water and forming agent.

Shaping

The mixture is then poured into a mold to form shapes, and the pressure is high.

Drying 

In this stage water is removed from the shaped bricks. This helps preventing the bricks from deforming or cracking which may result due to the rapid evaporation

Firing 

This is the most crucial process in refractory manufacturing. The modeled bricks are fired at high temperature to complete their thermochemical reaction so that they do not deform.

Inspection 

The bricks' physical and chemical properties are inspected very carefully by rigid quality management procedures.

Packing shipment

We guarantee efficient delivery every time.

Q:What can be applied to the burned refractory brick to resist heat shock?
Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
Q:Is the quality of refractory brick influenced if it is soaked by water
No refractory brick is not afraid of water
Q:does furnace use refractory cement to make refractory bricks?
consistence Mainly concern about the strength, generally masonry mortar does not consider the degree of fire resistance
Q:The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.
There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.
Q:Whether yellow dextrin is used in refractory bricks?
The production of refractory bricks needs yellow dextrin as bonded materials.
Q:What is the name of the white clay refractory brick
The name of white clay is kaolin clay
Q:What is the best color of refractory brick
Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality
Q:What material is sk-34 on the refractory brick
Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products
Q:What are the reasons for the production of waste in the formation of fireclay bricks?
The reasons for the production of waste when form fireclay bricks: Tile size is unqualified. This is due to the mold installation is not firm, the template transfers when molding; if the amount of material being added fluctuates largely, also can cause the body size changing. Ji Yangon Chi lie charge generation layer containing decyl poke pull and crack. The molding operation does not according to the principle of the light first and the thick later. At the initial pressure, the air doesn't releases, which causes the elastic aftereffect by repressing. Too much mud water, uneven mixture and inequal template all can make the body produce layer crack or crack. Twist. The template is used for too long, the template deforms, so raw brick deforms, the amount of water is too large, brick naturally deforms, causing the body twist. Miss edge and angle. Because of poor plasticity of mud, particles segregate, feeding back corner is not real, the body will appear side missing and angle modulation phenomenon. Bias voltage. Due to the deflection of the die head or the uneveness of mold bottom. Loose。 Due to insufficient feeding amount or insufficient pressure times.
Q:What are the hazards of solid clay bricks?
The production of clay brick destroys 500 thousand mu per year
