Product detail:
Riser Tube( Stalk Tube)---For low pressure die casting of cylinder heads and wheels.
Reaction bonded silicon nitride (RBSN) is made by direct nitridation of a compacted silicon powder. The nitridation produces only a small volume change, which means that RBSN components do not need to be machined after fabrication and complex near net shapes can be produced in a single process stage.
Application: Silicon nitride stalk is widely used in the molten aluminum foundry, melting and holding furnace,etc.
Handling Precautions:
Avoid severe mechanical impact.
Avoid rapid cooling over a wide temperature range
Assemble and install only in moisture free conditions.
Preheating in the air before application by temperature of 300 and 500 centi-degree.
Periodic Maintenance:
Remove slag deposits before solidification from stalk tube surface weekly.
Improper installation of seals may cause failure due to mechanical
stress.
