Features of Refractory Fire Bricks for Sale
- Basic features of refractory fire bricks
- Chemical Composition: Refractory materials’ quality and characteristic is decided by their main chemical composition.
- Bulk Density: The density is high, the compactness is good, the strength is high and the thermal conductivity is great in unit volume weight.
- Apparent Porosity: Fire Brick Company should strictly control the refractory bricks materials’ apparent porosity.
- Refractoriness Under Load: It is also called high temperature load initial change. Its reference is very important showing the refractory bricks materials’ high temperature resistance property.
- Compressive Strength: Ability to bear the highest pressure in the common temperature.
- Thermal Shock Resistance: Ability to resist the quick change of temperature without damage.
- Flexural Strength: Ability to bear cut pressure.
- Linear Change Rate: The change of bulk expansion and shrinkage at the same temperature every time.
- Physicochemical property
- Wear Resistance: It is one of the best indexes of refractory bricks materials.
- Thermal Conductivity: It means the heat flow rate that goes through the materials’ unit area at the condition of unit temperature gradient, which is related to apparent porosity.
- Shock Resistance: It results the materials’ long service life.
- Slag Resistance: Ability to resist slag erosion without damage at the high temperature.

Application of Refractory Fire Bricks for Sale
- High Alumina Refractory Bricks contain more than 75% Al2O3 content. Their refractoriness is higher than fire clay bricks. High alumina bricks have good acid-base erosion resistance and long service life and are suitable for burning zone in cement kiln.
- Dolomite Brick has good property of adhering coating, great erosion resistance. But it is difficult to transport and storage, this kind brick is not common used.
- Magnesite Chrome Brick has good adhering coating property and is mainly used for firing zone. But its thermal shock resistance is bad. Choose another brick to replace it.
- Spinel Brick is mainly used for transition zone with good thermal shock and reduction resistance. But its refractoriness is lower.
- Silicon Carbide Brick has low thermal expansivity, good wear resistance and thermal shock resistance. Its refractoriness is about 1800℃ and refractoriness under load is about 1620~1640℃. It is suitable for cooling zone and kiln site.
- Silicon Mullite Brick has good thermal shock resistance, high strength and great wear resistance for application in transition zone.
Manufacturing Process of Refractory Fire Bricks for Sale
Selection for Raw Materials
- Adopt superior bauxite chamotte as the raw material.
- Pyrophyllite fines: 325mesh. Its main ingredients: Al2O3≥18%, Fe2O3＜0.5%, K2O＜0.3%.
- Binding clay: soft clay 190mesh. Its main ingredients: Al2O3≥34%, Fe2O3＜1.0%, K2O＜0.3%.
- Clean away the impurities before production because the bauxite has been keep in the open air for long time.
- Put calcined bauxite into crushing system and select with 3.0mm screen cloth.
Granularity need: ＞3mm, 3-1mm, ＜0.088mm,
4-8%, ＞60%, ＜10%
- Grind Part oversize into fines through raymond mill.
Granularity need: ＜0.088mm, ＞95%
- Separate the two production lines in one workshop strictly. One line produces high alumina bricks. Clean up the crushing system before production. Discharge the clinker and fines into the stock bin for standby application.
- Weigh 32 Kg Pyrophyllite and 24Kg clay, and then put into one bag for reserve.
- Charge mixture
Adjust granule and fines according to pug situation. In addition add clay and pyrophyllite on the sand mixer and the quantity cannot be adjusted.
1. The charging sequence should be same with silica bricks materials. Net mixing for 15 minutes. There should be no mud pie and drier in the material.
2. Pug size composition: Adjust moisture according to the molding situation.
1. Bulk density of High alumina bricks green brick is 2.95g/cm3
2. Apparent porosity of green brick is 22~23%
3. Size standard of semi-finished product of high alumina bricks: When green brick size is less than or equal to 100mm, its error is about 1mm. When green brick is about 100~200mm, its error is about 1.5mm. When refractory fire brick size is more than 200mm, its error is about 2mm.
