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.

- Q: is it correct that the higher the refractoriness is, the better refractory bricks are?
- Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
- Q: when to replace the worn refractory bricks in rotary?kiln?
- But also depend on the other conditions of the furnace, many aspects should be understood, not only to see the degree of wear!
- Q: What kind of material is good to be laid on the kiln car, refractory brick?
- Ceramic fiber blanket
- Q: Where the refractory bricks rider bricks that are used for building arch and vault should be put?
- Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
- Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
- Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
- Q: What are the materials for building blocks and what are the specifications?
- According to the production process, it is divided into sintered brick (fired brick), autoclaved brick and steam curing brick.
- Q: What is the upper limit of high temperature resistance of refractory bricks and refractory soil?
- In a variety of colors; if it has small amounts of Ti4 and Fe2, then it is blue, vanadium and other trace elements, brown red color, which include red, yellow and other colors, the Ural mountains of Russia; corundum is aluminum oxide (Al2O3)mine. Some crystals contain six symmetrical distribution and other needle like rutile inclusions, they are called star ruby or sapphire stars, but because they often exist fracture, black and other colors on the bottom surface of the colorless or rhombohedral decent form polysynthetic twin, a drum shaped six square column, iron, yellow, blue and green, the color of sapphire is decided by the chemical composition contained in titanium, no cleavage, gray, yellow sapphire etc.. Sapphire often is known for its color name, such as white sapphire, sky blue, including South Africa as the main origin of the Transvaal, more than 1500 sapphire calls corundum, brown. Corundum has glass luster, and is common seen in alluvial placer, purple, named ruby. Produced igneous and metamorphic rocks, which are relatively barren. Sapphire is all colors corundum gems except red series of corundum gems. Does ruby refer to corundum with all red hues? No, violet sapphire is mainly used as high-grade abrasive, its red is mainly caused by the chemical composition of trace elements chromium, blue sapphire is the most popular in the world, pink. The crystal belongs to the three party system, green. Usually it is white, gold sapphire, are precious gems, they can produce six star awn, some are needle or clintheriform, green sapphire. Aggregation is block or columnar.
- Q: How to prevent high alumina refractory brick from producing crack when reproduce high alumina refractory brick?
- 1-1, on the 1 in order to prevent the emergence of crack in the production of high alumina refractory brick. 2 is appropriate, the water absorption rate of the tube mill should be controlled below 6%, the excess air coefficient controlled between level 1 and 2. The water absorption rate of clinker of bauxite with high alumina controlled under 4%-5%, making the high aluminum refractory brick burning in a smoothly and steadily weak oxidation atmosphere, and should be adjusted by thermotechnic
- Q: cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?
- 1, Portland cement should be. Should use aluminate cement CA625. 2, and high alumina fragment yellow sand limestone should be mixed with high temperature solution 3, add some area of reinforced steel and steel can be thin or thick, but 6mm's diameter and 50mm's spacing of steel are suggested 4, according to the situation, add CA625 about 15%, brickbat about 60% and brick powder about 25%; 5, mixing with water to cement mortar until it is slightly thicker
- Q: Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
- The heat preservation effect should be taken away from the heat insulation capacity of the material. The ordinary clay brick has small heat capacity and slow heat conduction, so it is more thermal insulation.
