SISIC beam high temperature resistance refractory Silicon carbide beams
1. Product Description
Yixing Kam Tai silicon carbide products have the excellent properties of high bending strength following rising temperature, thermal shock resistance, oxidization resistance, corrosion resistance and so on.
The series of products are widely used in the sealing equipments and slipping equipments, for the fields of metallurgy, chemical industry, pharmaceuticals industyr, food industy, corrosion resisting pump, automobile, mechanism, etc.
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-resistance,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.

3. Features
- Excellent thermal stability and distortion resistance at high temperature.
- High mechanical strength at high temperature
- Excellent thermal shock resistance.
- High thermal conductivity.
4. Package
Wooden case and wooden pallet or pack as customer's requirement
We use plywood box and pallet, no need to do fumigation.Some countries has very strict law about pacakge, if we use solid wood, we must do fumigation, otherwise it will bring trouble when customer import.So we use plywood, it is also high strength and quality, we export to many countries.
