The aluminum titanate has higher melting point,lower thermal expansion coefficient and excellent heat-shock resistance .Besides,the aluminum titanate don't infiltrate with the metal melt(especially the non-ferrous metals) and glass melt.Therefore aluminum titanate can be widely used in the conditions of high-temperature resistance,heat-shock resistance and corrision resistance.
The aluminum titanate riser tube is the key part of the low pressure aluminum casting machine,the features are as following:
1,Excellent thermal shock resistance
2,No infiltration with the non-ferrous metal
3,Excellent wear resistance
4,Low thermal-expansion coefficient
5,The service life of the aluminum titanate riser tube can reach 60 days , can enhance the production efficiency and reduce the cost.
6,Isostatic Forming
7,Exact dimensions machined by CNC
The long-term practical use proves that SG-28 Silicon Nitride Ceramic is very suitable for low-pressure casting machines and dosing furnaces. Compared with traditional cast iron, silicon carbide, carbon nitrogen materials and Aluminum Titanate, Silicon Nitride Ceramics have the best high-temperature strength and the service life can last for more than one year. The low wettability to aluminum liquid, makes the SG-28 Silicon Nitride Ceramic effectively reduce the slagging on the inner and outer walls of the riser tube, reduce the shutdown loss and maintenance. SG-28 Silicon Nitride Ceramic has excellent corrosion resistance, which can effectively reduce the pollution to the aluminum liquid, and improves casting quality.
Riser Tubes Stalk Ceramic Pipes by Nitride Bonded SiC (silicon nitride silicon carbide): max working temp 1450C , Material by NSiC, Si3N4-SiC, Perfect resistance of Al, Zn, Cu.. Special for Low pressure Die Casting Machine, also work as thermocouple sheath. Size and shape is available by China SnDou SiC Ceramics manufacturer.
