CH Refractories manufactured EAF Gunning Mix can be used for both hot and cold patching, with long service life and competitive price.
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, ghttps://www.chrefractory.com/wp-admin/edit-comments.phpood sintering, good erosion resistance, and can be used as cold or hot refractory repairs materials at slag line and side wall.
◆ EAF furnace of steel plant
Wet spraying technique has no pollute to environment and no CO2 and 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.
