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's the reason of cracks in refractory bricks?
- The relative density is high, and high temperature heat treatment and increase the strength of qualitative brick, for 10 days, then only the shorter time for heating and drying and dehydrating, you can smash a brick if it's a long time! There will be a stress loose phenomenon making bricks now, the internal density of these crack bricks are not the same, in addition to the effective drying, dehydrating and heating treatment, the time distance is small, basic bricks and finished bricks adopt line production, when drying, the water is also evaporated at the same time, the central density should be high ! The reason is very simple, the greater extrusion force the brick bears in the molding, the closer to the edge, the smaller density is, the better to keep forming, the shorter residence time, the higher the rate of finished product is, which belongs to the natural drying, this phenomenon is more obvious
- Q: What types of refractory bricks are divided into?
- middle rank。 A refractory is stronger than B refractory, low rank, the other is refractory, the senior is AB. Shale is hollow, it is not refractory, refractory, advanced, refractory B, there are nonfireproof materials in intermediate and low rank. Three types of refractory A
- Q: What are the differences between sintered bricks and refractory bricks?
- Easily weathered. There is no obvious difference in the usage between fired pavingbricks and refractory bricks; sintered bricks are generally used for residential road and landscape engineering, they do not fade; refractory bricks are used for all kinds of kiln constructions in plant: It is not anti-freeze (when the temperature is below the zero degree, the brick will easily "blister" in the saturated state), the reasons are high compressive strength and high temperature zone' heat insulation and so on. Fired pavingbrick is a powerful vacuum extrusion type. Fire suppression road brick is high temperature furnace brick, which is not suitable to be used as road brick. Its characteristics are: Wear resistance and freeze-thaw resistance (the anti freeze-thaw cycle of brick is more than 50 times in saturated state), non weathering, sidewalks, short service life. Sintered brick belongs to the building material, refractory brick belongs to the industrial kiln material, which is easy to moss
- Q: which kind of refractory bricks do coke oven and oxtongue brick belong to ( ) A, silica?brick B, clay brick C, high alumina brick
- Beef tongue is to regulate the flow of gas, gas flow is not the same, so is the temperature, so choose the temperature resistance brick which is clay brick only.
- Q: Are buildings allowed to use red bricks?
- Clay brick is forbidden to be used by the state, whether red or green. Red and cyan are just the difference between making techniques. Now also produces appearance and clay sintering, red brick like silicate sintered brick can be used.
- Q: Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
- The price of concrete solid bricks and the price of MU10 bricks are on the same level, and the difference will not exceed two cents a penny. It should be MU15 sinter ordinary brick is more expensive.
- Q: What mud is the refractory brick made of?
- The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.
- 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: The difference between clay bricks and clay bricks?
- Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.
- Q: The application of wasted refractory bricks
- break it and refine copper, its grade is higher than the ore
