Reaction bonded high temperature bearing Silicon carbide beam
1. Product Description
Reaction bonded SiC beam is made from α_SiC powder, graphite powder, mixing additives and organic adhesive agent.The mixture body is extruded and then filled into crucible with silicon powder. Sinter in a vacuum heating furnace at 1600 ~1800° C, the melt silicon powder reacts to the silicon in the body, finally from β-Sic due to the heat of reaction.

4. Applications
Silicon carbide beam is mainly used as the load carrying members of tunnel kiln, shuttle kiln and double channels kiln. It can also be used as the kiln furniture in ceramic and refractory industry.
We use plywood box and pallet, no need to do fumigation.Some countries has very strict law about pacakge, if we use solid wood, we must do fumigation, otherwise it will bring trouble when customer import.So we use plywood, it is also high strength and quality, we export to many countries.
1. We are a manufacturer, which can control the cost easilier than trade company also can give you anwer more quickly.
2. As a manufacturer, we know much in technique and can give you more support in technique problem.
