QUNHUI Tunnel kiln car brick/Cell Block the dry pressed method which enables high dimensional accuracy and homogenous texture.
Our kiln car refractory system takes in account of the severe stress due to the continual heating and cooling cycles with the following objectives:
· Lightweight to ensure low energy consumption.
· Airtight interlocking between kilns car to ensure low kiln car bottom temperature.
· Longer service life.
