Abstract
Provided is a manufacturing method of a recycled plate for a sliding nozzle, which is capable of repairing damage of a plate used for a sliding nozzle to extend an endurance period and widens a range of the used plate as a target for recycling. The manufacturing method of the recycled plate performs, on a plate used for the sliding nozzle, recycling processing including impregnating a matrix of the plate that is formed by a refractory brick with liquid containing at least one of tar and pitch, heating the plate impregnated with the liquid to remove a volatile component, grinding a surface of the plate after having been impregnated with the liquid and heated, and bonding a plate material to one surface of the plate after having been grinded.
