Refractory Magnesia Gunning Repair Materials
Product Description
Refractory Magnesia Gunning Repair Materials
Produced from magnesia gunning material with high quality magnesia sand and special binding material. It is mainly used for repairing the lining of electric furnace, rotating furnace and other industrial furnace.
Refractory Gunning Mix is a kind of unshaped refractory material used when repairing the lining of thermal kiln equipment by spraying construction method. It is composed of 0-5mm particle gradation, with a chemical binding agent and admixture. Refractory Gunning Mix coatings can be used to spray new linings, and can also be used to repair furnace pipes. It is not only convenient for construction but also has a good effect in extending the service life of the kiln and reducing the consumption of refractory materials.

Types of Refractory Gunning Mix Coatings
Refractory Gunning Mix coatings are divided into light Refractory Gunning Mix coatings and dense Refractory Gunning Mix coatings. The materials selected according to different use environments include corundum, high alumina, mullite, clay, SiC, and magnesia. Mainly used in hot blast stoves, heating furnaces, and soaking furnaces, blast furnaces, flues, and chimneys, etc. However, the price of light-weight is relatively more expensive than dense Refractory Gunning Mix coatings.
The body density of dense Refractory Gunning Mix is generally 1.6-1.8g/cm3. However, the different requirements in different furnace pipes, especially the sintering machine pipes, must be much better than other parts, that is, the Refractory Gunning Mix paint with a density of 2.2g/cm3. Of course, the price of Refractory Gunning Mix coatings for sintering machines is much higher than that of Refractory Gunning Mix coatings for other parts.
