Ceramic tubes are 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.

The features of products•Lighter stronger and easy to assemble
•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 .
•Good thermal shock resistance
•higher working temperature
