Silicon Nitride Dosing Tube

silicon carbide bonded Si3N4 silicon nitride (SiC) riser tube in nonferrous metal casting

Silicon Nitride (Si3N4) is a new type of advanced refractory materials, which is used widely in metallurgy industry. Silicon nitride riser tube is the key part in low pressure casting machine used for non ferrous metal casting, especially for aluminum casting.

Silicon nitride riser tube have excellent characteristics, such as high temperature resistance, excellent corrosion resistance and abrasion resistance, low thermal conductivity, excellent thermal shock resistance, uneasily oxidized, high strength, no pollution aluminum liquid, lifetime is 3-5 times than ceramic tubes. After using ,not only can improve the quality of the casting products but also can reduce the times of replacement and save money and time.

We can offer different sizes riser tube, and can also customized according to drawing.
