SiC riser tube, also called SiC lifting tube, SiC stalk tube, is made of our own SiC raw material, which is fired under 1400℃ to generate nitride boned silicon carbide ceramic(NSiC, nitride bonded SiC). 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. We are able to produce customized ceramic riser tube according to your drawing.

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.

SiC riser tube performance compared with cast iron riser tube/aluminum titanate riser tube

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 SiC Raw Material

Smelted with pure petroleum coke, Hongyuan make SiC raw material by ourselves. Smelted with pure petroleum coke, we make SiC raw material by ourselves. We have completed 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. Hongyuan is the original SiC riser tube manuafcturer, SiC stalk tube factory, in mode of direct factory sale. You are welcomed to buy SiC riser tube, to get SiC riser tube price and to get SiC riser tube parameter.
