The function of the kiln lining in the rotary kiln is to protect the cylinder body from high-temperature damage, play a heat-insulating role, and reduce heat dissipation loss. Usually, refractory bricks are used. The repair of the rotary kiln lining mainly includes steps such as inspection, demolition, repair, and replacement. Before repair, it is necessary to ensure that the temperature inside the rotary kiln is reduced to a safe level so that personnel can enter to check the damage of the refractory bricks.
