Gun mixes for blast furnace

High strength&insulating fibre gun mixes (Patented product)

On the basis of general gunning and dry gunning, we develop the high strength insulating fibre compound gun mixes.(Patent No.:200610017726.1) It improves the insulating performance, reduces the heat loss, avoids overheat of furnace shell and increases the blast temperature. Relevant chemical adhensive should be added when in use. By high-pressure gunning, the high strength ball fibre,adhensive and refractories are gunned to the surface, forming strong fibre refractory cohensive body.

The gunned layer has advantages of high strength, light weight, insulating, energy-saving, etc.

1. Low reflectivity. Reflectivity less than 18%

2. Small thermal conductivity and excellent heat conservation effect.

3. Reduce the heat loss of blast furnace and hot blast stove. Longer the work life. Save the cost. It has good economic and social benefits.
