INTRODUCTION:
Nsic Silicon Nitride Riser Tube for Melting Aluminum Nsic riser tubes Silion Nitride Riser Tube, Nsic Riser Tubes, Melting Aluminum, Riser Tube, Nsic Tube, Silicon Nitride Riser Tube our product has some exceptional features as follows: a.excellent thermal conductivity, thin wall (only 10 mm or so), so the product of the reaction is very sensitive to temperature changes, high thermal efficiency, saving energy, and the temperature of the reaction true and accurate; b. Excellent thermal conductivity, low thermal expansion; c. High washing resistance, oxidation resistance, acid resistance and thermal shock resistance; d. Low wettability with the melts, bring minimum impurities to the melts; e. High cost performance, long service life. Also we can supply tubes made of other materials or by different process, for example, Si3N4 (SSN, RBSN, G.P.S-SN, HPSN), O'SiAlON, aluminum titanate, dense fused silica and coated cast iron. Please contact us if interested. Applications: Low pressure die casting and counter pressure die casting of molten aluminum, aluminum alloys, magnesium alloys and copper alloys.
