According to the actual production situation of reheating furnace and combined with the new technology of refractory material, FUHAO developed the quick dry explosion-proof self pouring castable and designed the " hot repair technology solution ofreheating furnace ". The solution can be used to repair the damaged part of the steel rolling reheating furnace lining. when the · lining is found damaged, the repairing only takes about 72 hours from reduce the output and cooling down to restart production.
