Abstract
An apparatus for automatically laying the refractory lining along the inner wall of a vessel (i.e., a metallurgical converter) which permits automatic repair of the vessel lining. This refractory brick laying apparatus comprises an operational center capable of being lowered and raised inside the vessel and comprising a lower table, an upper table and a rotary cage arranged between the upper table and the lower table and connected to each of these by a runway block. The upper table or lower table has a sufficiently large orifice to allow a pallet of refractory bricks to pass inside the rotary cage. Arranged on the rotary cage is a robot which has at least three degrees of freedom, such that it can reach all points of the working range. The end of the robot is equipped with a gripping device for automatically picking up, handling and laying the bricks intended for forming the refractory lining.
