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: How many years are the service life of chimney lining refractory brick?
- Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite
- Q: can the red brick be used as refractory brick?
- 1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.
- Q: Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?
- Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
- Q: What are required for high temperature refractory bricks?
- High temperature resistance, high pressure resistance
- Q: What is the refractory temperature of refractory bricks?
- First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
- Q: What building materials can take the place of clay bricks?
- Are aging fast, can greatly save the time, from the practical results, the red brick walls every day only skilled workers built about 2.5 cubic meters, while the foam concrete block can be built about 6 cubic meters per day, calculated by 50 yuan per person per day, only a fee per cubic wall can save nearly 16 yuan.
- Q: How to prevent the refractory bricks from burning to crack?
- This may result from formula. Prevent the refractory bricks from being overweight. Firstly, sintering agent should not exceed the standard, when sintering, bricks must be well piled to piled bricks, and the bricks must be dry.
- Q: What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
- 123
- Q: Do refractory bricks resist corrosion and sulfur?
- The refractory brick just plays the role of resisting high temperature and insulating heat.
- Q: Why are clay bricks used when buildings are below zero? Frost heaving, water absorption, or something?
- The clay brick has a certain strength, and has better heat insulation and sound insulation performance, and the interior wall of the winter can not appear condensation phenomenon, and the price is low. Although a variety of new wall materials are emerging, clay bricks will still be used as a main material for masonry work in the future
