The primary use of high alumina refractory bricks:

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

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

The main features of high alumina refractory bricks:

1.Have low thermal conductivity, are resistant to rapid cooling, acid corrosion, vibration and so on.

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

Here is our process flow:

Our conventional packaging :

1. We choose appropriate wooden trays to support the bricks and their edges and corners are covered with cardboard, and then, use a strong packing belt to fix the whole package and wrap multi- layer protective plastic round.

2. We can also pack according to your requirement, such as using cardboard to cover the whole package.
