1. Applications

 Alumina ceramic elbow  is refractories consumables used for gating system(running system) during casting, which includes funnels, tubes, bends, tees, etc. as seen from following photos.

They are widely used for casts of tens of KG to hundred tons in cast steel and cast iron foundries, which could effectively improve cast quality, and highly recognised by various foundries.

 

 

2.The features of our products

 

 Lighter strongerm and sawable for ease in assembly (could be sticked together wiht stickers

 

 Smooth internal surface promoting streamlined flow and reduce contaminant pick-up. 

 

• accurate and consistent dimensions
•  reduce casting defects of sand holes, sand-flushing, and sand inclusions.
• metal erosion resistance much better than traditional refractories
