Semidry Process Gunning Mix of Coke
【Application】
Apply to any part of the repair of coke oven, in particular, for cracks and small cavities in the deeper erosion of the wall patch.
【Performance】
Facilitate the construction site, the repair time is short, do not need to shutdown cooling, direct spraying cleaning patch and put into operation, greatly reducing the recovery time lining;
High-temperature performance and high temperature environment, this product combined with the original refractory material high strength, wear-resistant anti-earthquake off, solid and durable.
