Sintered Si3N4 riser tube/pipe for Aluminum Industry

Silicon Nitride, mainly consistaing of Si3N4, is a gray hard and solid high performance ceramic material sythesized through several chemical reaction methods. STA offer three sintering methods for Silicon Nitride, Gas Pressure Sintering(GPSN), Hot Press Sintering(HPSN) and Reaction-Bonded Sintering(RBSN). Parts are pressed and sintered by well devoloped methods to achieve the outstanding properties.

This high performance ceramic material has the strongest covalent bond properties next to silicon carbide, it's used as high temperature ceramic components due to its superior hardness, strength and excellent thermal shock resistance, these properties make it ideal for use in mechanical, thermal and wear  applications. 

Although Silicon Nitride has high hardness, we owns strong machining ability to meet customers' requests on

sophisticated designs, tigth tolerances and smooth surface.

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

1.The diameter of Si3N4 bonded SiC thermocouple protection tube is Φ12-80mm,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.

2.Liquid tube,heating sheath,protection tube:used in aluminum liquid and glass liquid.It has good thermal conductivity,corrosion resistance,compression resistance,long life ect.

3.Roller tube:used in brick kiln furnace on the ground,diameter Φ30-50mm,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.
