Magnesian  daubing materials for coating.
the main raw material of magnesite coating is two kind high quality magnesite, through adding the compound binding agent. compound antiespioding agent, raising intensity agent,raising plastic agent and reducing water agent to finish the manufacture. it possesses good properties for construction or repairs , high resistang of the cinder and molten steel corrosion,can not burst at baking, disintegrating easy.

construction for magnesian daubing materials for coating
at the operation site added the water about 15% , in the mixer to stir about 8 minutes, by the time the magnesite coating appearing a certain viscosity then can use to daub.
before daubing, must clear the remainder on the permanent liner, its thickness  may according to the part of the internal liner to determine.
the coating layer may curing in natural, or baking direct, low temperature 100-150C. baking 1-5 hours,m middle temperature 400-500 C. baking 1-5  hours last baking 2-5 hours at temperature 800-1500c. then may put into using.
