Ladle gunning mix
The ladle gunning mix main raw materials of this kind of product are corundum and magnesium aluminate spinel, which can be used for ladle lining repairs
considering the destructibility of slag lines and easily worn parts of ladles, our company specially developed series of refractory gunning mix with the unique binding agent and additives.
Advantages of Gunning Mix:
•Wet spraying technique has no pollute to environment and no CO2、CO when using in carbon-free ladle,and it’s geared to the carbon free and environment- protected and environment friendly technique.
•This gunning mix could be endlessly cycle used to lower the refractory materials consumption and waste appearance and work with key role on the ladle continue and safety use.
•This gunning mix has no pollute to the molten steel, and compared with the current lining materials, it has the characteristic that long service life, low cost, high construction automatically, and energy conservation and environment protection. High potential value among the steel plant.

CH Refractories manufactures different brands ladle nozzle and collector nozzle for various capacity ladle, which can meet different service life requirements.
Silica refractory brick is fused silica refractory，a acid refractory brick which mainly consisting of tridymite, cristobalite, and a small amount of residual quartz and glass phases. The silicon content is 94% or more. True density of the silicon brick is 2.35g/cm3.
Corundum bricks include fused cast corundum brick, fused alumina corundum brick and sintered corundum brick. fused cast corundum brick is manufactured with commercial alumina and little sodium carbonate and quartz powder fusing in the quartz powder and through process of casting and annealing, and then form the shape and size through machining.
