Si3N4 bonded SiC ceramic refractory material, is mixed with high pure SIC fine powder and Silicon powder, after slip casting course, reaction sintered under 1400~1500° C. During the sintering course, filling the high pure Nitrogen into the furnace, then the silicon will react with Nitrogen and generate Si3N4, So Si3N4 bonded SiC material is composed of silicon nitride (23%) and silicon carbide(75%) as main raw material, mixed with organic material, and shaped by mixture, extrusion or pouring, then made after drying and nitrogenization.
Si3N4 bonded SiC as a new type refractory material, is used widely. The applying temperature is 1400 C. It has better thermal stability, thermal shock, which is better than plain refractory material and recrystallized SiC. It also has antioxidation, high corrosion resistant, wear-resistantance, high bending strength. It can resist corrosion and scouring, be no polluted and fast heat conduction in molten metal such as AL, Pb, Zn, Cu ect.
Please check below specification:
The diameter of Si3N4 bonded SiC thermocouple protection tube is Φ 12-80mm, length is 1600 mm. It can be usded in high temperature kiln furnace and all kinds of atmosphere. It also can be directly used in all kinds of melted liquid.
Liquid tube, heating sheath, protection tube: Used in aluminum liquid and glass liquid. It has good thermal conductivity, corrosion resistance, compression resistance, long lif ect.
Roller tube: Used in brickkiln furnace on the ground, diameter Φ 30-50mm, length within 1600mm, high temperature resistance, no deformation, high strength
4. Kiln furniture: Used in tunnel kiln, shuttle kiln, down draught kiln, with good carrying capacity. It is ideal kiln furniture for increasing output of kiln furnace and make good use of space of kiln furnace.
5. Sagger: Used for firing high grade refractory material, rare metal, powder metallurgy, electronic components and various loose material. Shape can be canister and rectangle.
6. Various refractory piece: With impact resistance, high temperature resistance, wear-resistance, good thermal shock resistance ect. Suitable for heat exchanger, cold air pipe, burner nozzle, crucible.
It can not only gain energy-saving effect, but also can keep product from pollution, and long life and convenient operation if you choose Si3N4 bonded SiC.

- Q: What is fireproof concrete?
- According to the different properties of fire resisting and heat resisting concrete, they can be divided into silicate, aluminate, phosphate, sulfate, chloride, sol and organic substance, fireproof and heat-resisting concrete, etc.. The following are mainly used silicate, aluminate, phosphate, sulfate fire, heat-resistant concrete.
- Q: In 2016, a few of the traditional refractory materials will be able to survive
- In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.
- Q: What refractory material does cupola lining use?
- Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
- Q: What are the specific raw materials for plastic pallets?
- With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.
- Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..
- Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
- People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.
- Q: Corundum, high alumina and fireclay refractory difference is what
- Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
- Q: What are the specifications for bricks?
- Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- Q: Does the chimney have high acid resistance?
- The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.
