Clay refractory bricks are mainly used for :

1. Tunnel kiln, blast furnace, hot air stove, coke blast-furnace, coking furnace, glass kiln, l-ime kiln, rotary kiln, ceramic kiln, and other high-temperature furnaces and  equipments  of the fire-resistant masonry and lining materials.


2. Can be used to make brick for kiln car, steel ladle lining brick, stopper head brick, furna-ce wall, bottom of the furnace, combustion chamber, flue, etc.

Clay refractory bricks mainly have these characteristics : 

1. With the features of low thermal conductivity, resistance to rapid cooling, acid corrosio-n, good shock resistance and so on.


2. Can effectively save the cost of the fuel in the furnace,  enhance  the  heat  preservati-on performance of the furnace and improve the heat utilization rate of the kiln.




Our process is like this :



Our conventional packaging :


1. We choose the appropriate size of the wooden tray support, the edges and corners are covered with cardboard, and then, the whole use of a strong packing belt tied fixed, finally, wrapped around the multi-layer plastic protective film.


2. We can also package according to your choice, such as around the whole cover cardb-oard or other requirements.
