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: What types of building blocks do you have?
- The commonly used shapes are mainly divided into hollow bricks and perforated bricks. In particular to the green landscape construction, decoration materials, building construction, there are many such as: ordinary brick, lime sand brick, sintered shale brick, porous ceramsite concrete permeable brick, lawn brick, pervious brick, hollow glass brick, ceramic tile ground, refractory clay, concrete block wall, floor tiles, solar LED lamp, floor tile dry spray the rubber brick, grass planting brick, brick, split brick, road brick.
- Q: Why limit sintering brick first and develop new wall material?
- Sintering brick in the production process, including fuel and many other aspects of pollution.
- Q: What are the disadvantages of sintered clay bricks?
- Advantages: brick is the traditional wall materials, has high intensity and durability, but also because of its porous and has the advantages of heat insulation, sound insulation and absorption, therefore suitable for building envelope, interior walls, exterior walls, columns, arches, chimney, channel and other structures have been widely used in masonry the building, is also available in mid proper or steel wire reinforced masonry concrete structure to replace the post and lintel.
- Q: Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
- the proportion of raw materials of refractory bricks and thermal insulation bricks. chain of various types of products
- Q: What is common brick, firebrick and hollow brick?
- Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
- Q: Why masonry walls must not be mixed with clay bricks?
- Generally speaking, the seismic performance of masonry structures is weaker than that of concrete structures. Therefore, it is possible to have some concrete frames or seismic walls in masonry, but the building must evaluate the seismic performance according to the masonry structure. But the concrete structure can not consider the masonry bearing, and the masonry wall is the self load wall or the light partition wall.
- Q: What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
- It should be the length of the turn. I'm not sure if it is right.
- Q: The state's policy on clay bricks
- Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
- Q: how to test the high alumina refractory brick mixed alumina?
- The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
- 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.
