EAF gunning mix
The EAF refractory gunning mix uses high quality magnesia as the
main materials, by adding compound binding additives, the series of
gunning mixes for EAF refractory repairs feature high adhesive
strength, low rebound rate, good sintering, good erosion
resistance, and can be used as cold or hot refractory repairs
materials at slag line and side wall.

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.
