INLET SEAL BOX EASY TO REMOVE ALIEN SUBSTANCE

摘要

PURPOSE: An inlet seal box for easily removing a foreign substance is provided to autonomously remove a foreign substance adhered on an inlet seal roll of a bright annealing furnace. CONSTITUTION: An inlet seal box for easily removing a foreign substance includes a roller unit (10), a roller pushing unit (12) and a cover unit (40). The roller unit positioned in an entering part of a bright annealing furnace rotates centering a shaft fixed on an internal wall of the bright annealing furnace and pressurizes a strip entering to the entering part of the bright annealing furnace. The roller pushing unit positioned in the internal wall of the bright annealing furnace seals the bright annealing furnace by being contacted to the roller unit. The cover unit is connected to an external wall of the bright annealing furnace by a hinge to be possibly opened and closed. The cover unit prevents foreign substances from entering the bright annealing furnace from outside by covering the roller unit.
