Abstract
A high temperature industrial furnace roof assembly wherein two refractory bricks are held in adjacent position by suitable securement and have a hanger rod extending from the assembly to suspend the roof assembly from a support structure in desired position in a furnace roof. The hanger rod is maintained in locked position when the weight of the roof assembly is placed upon it. The hanger rod may be depressed into the refractory bricks permitting free rotation of the hanger rod with respect to the hanger and brick assembly and locked into desired position at 90.degree. increments by a force applied to the hanger rod in a direction away from the brick assembly. The roof assembly of this invention is particularly desirable for furnace roof repair and provides for easy installation in operating high temperature furnaces permitting the long axes of the repair assembly to be changed on the jobsite by rotation of the hanger.
