 Silicon Red Bricks Definition
 
There are also new developments in the types of silica bricks. Silicon red bricks are one of the silica bricks. Silicon red bricks are an improved product based on silica bricks.
 
The main crystal phase of silica brick consists of high-density mineral corundum (Mohs hardness 9.0 to 9.2), silicon carbide (Mohs hardness 9.0 to 9.5), mullite (Mohs hardness 7.0 to 7.5). The structure of the product has a high density, the bulk density of the silicon red brick is generally between 2.7 and 3.0 g/cm3. The normal temperature wear resistance of the refractory material depends on firebrick strength and compactness of the structure, the material with high strength and high density has good wear resistance. The lining of cement rotary kiln has been subjected to rolling friction of materials for a long time, the wear of silicon fire brick is one of the main reasons for the damage of refractory lining. The density, strength and wear resistance of silica bricks are significantly better than those of anti flaking high alumina bricks and magnesium aluminum spinel bricks. Silicone bricks have good effect in the secondary firing zone and filter belt of cement rotary kiln. Silicon red bricks can be said that the wear resistance plays an important role.
 
Silicon Red Bricks Features
 
1.Red Silicon Bricks Have High Softness, Excellent High Temperature Resistance
 
The actual detection value of the load softening temperature is stable above 1680 ℃, which has been greatly improved on the basis of silicon molybdenum brick, which is comparable to magnesium alumina spinel brick.
 
2.Red Silicon Bricks Have High Strength, Wear Resistance, not Easy to Peel Off and Erode
 
The actual measured value of the strength is stable at 160 MPa or more, which is more than three times the strength of the spinel brick. The strength is increased, silicon red bricks is not easy to be damaged during handling, and the wear resistance can be fully improved, so silicon  red brick is very suitable for use at 2-3 meters in the kiln mouth.
 
3.Red Silicon Bricks Have Low Thermal Conductivity and Good Thermal Insulation
 
Since the silicon molybdenum brick is still a high-alumina-silicon carbide product, silicon refractory bricks material properties determine silicon refractory bricks lower thermal conductivity. In the same period, the simplified temperature can be reduced by more than 50 ℃.
 
4.Red Silicon Bricks have Strong Flexibility and Excellent Thermal Shock Resistance
 
Red silicon bricks have good thermal shock stability, able to fully adapt to the environmental requirements of frequent fluctuations in the front transition zone temperature.
 
5. Red Silicon Bricks have Moderate Density and Reduced Simplified Load
 
the volume density of silicon red brick is 8% lower than that of magnesia-alumina spinel brick, resulting in a reduction of 8% or more in the unit length of the same kiln type.

Silicon Red Bricks Application
 
Silicon fire red brick is a transition strip brick developed according to the demanding requirements of large and medium-sized cement rotary kiln for refractory materials.
 
Firebricks silicon red bricks further strengthens the thermal shock resistance and thermal insulation effect on the basis of conventional silicon molybdenum. At the same time, the load softening temperature is increased, the transition zone of the rotary kiln and the cooling zone are used above 3000-10000t/d, the excellent performance is outstanding, the service life is higher than other refractory bricks products.
 
Silicon Red Brick Used in the Cement Rotary Kiln Reason
 
1. Silicon refractory red bricks have excellent wear resistance.
 
The wear resistance coefficient of silicon red brick is 8.2cc, the normal service life can reach 12-24 months, achieving the goal of 2 major overhauls in 3 years.
 
2. Refractory silicon red bricks Load softening temperature is high, high temperature performance is good.
 
The load softening temperature of the silica brick is above 1450 ℃ and the height is above 1650℃. The temperature of the brick surface of different parts of the lining of the non-cement rotary kiln is different. The temperature of the secondary firing zone and the front transition zone is about 1400℃, which is higher than the temperature of the brick surface of the firing zone because of the kiln skin protection after firing, the brick surface temperature is 900 to 1000 ℃.
 
3. Silicon red bricks have high thermal stability.
 
The transition zone of the rotary kiln is especially near the wheel belt. The temperature changes frequently and the mechanical stress is large. Due to the poor thermal stability of the traditional refractory material, the service life in the vicinity of the wheel belt is even shorter than that of the firing belt. Silicon red brick has good thermal stability. After testing, refractory bricks thermal shock stability is 1100 degrees Celsius water cooling can reach 15 times. Therefore, silicon red brick is especially suitable for the transition zone near the wheel belt, effectively extending the service life.
 
4. Silicon red bricks have good thermal insulation and reduce kiln temperature
 
The thermal conductivity of silica red brick [2.3 ~ 2.5W / (m · K)] is lower than that of alkaline products [2.69 ~ 2.74W / (m · K)], so the thermal insulation effect of silica red brick is better. In the large-scale rotary kiln, the secondary firing zone, the transition zone, the pre-tropical zone, the kiln tail, the tertiary air duct, the decomposition furnace, the like are made of silica brick. Compared with the alkaline brick, the surface temperature of the cylinder is reduced by 100 ℃or more.
