SiC Riser Tube
About SiC Riser Tube / Lifting Tube /Stalk Tube
Made of our own SiC raw material, SiC riser tubes are excellent to work in high temperature aluminum liqiud, able to stand corrosion, no contamination to liquid. It is widely applied in metal industry especially aluminum low pressure casting.
Application?
nonferrous metal casting area, especially low pressure casting.
Features?
1.anti-melting and anti-corrosion, no contamination to metal liquid;
2.good at thermal shock resistance, no dreg or crack;
3.airproof, no aluminum adhered, no slag accumulated, preventing air hole on casting piece;
4.easy maintenance, long life-time, cost-effective.
performance compared with other materials
| Material | Features |
| cast iron riser tube | good air tightness; cheap price; with Fe contaminating aluminum liquid; short lifetime |
| aluminum titanat riser tube | not contaminating aluminum liquid;good air tightness; poor in strength; poor in resistance to thermal shock; short lifetime |
| HONGYUAN NSiC riser tube | not contaminating aluminum liquid; anti-corrosion; better in resistance to thermal shock; longer lifetime |
High Quality of Raw Material?
Smelted with pure petroleum coke, Hongyuan make SiC raw material by ourselves. We are the only one in China having complete SiC products chain:
SiC crystal smelting- SiC grains- SiC ceramic products
Advanced Equipments for Firing?
The automatic nitriding furnace in the largest volume, controlled by microcomputer, were honored the First Prize of China Machinery Industry Science and Technology Award for the residual-heat utilization system, meanwhile this nitriding furnace gaining state's utility patent.
