ABSTRACT:
Refractory door jamb assemblies for high temperature furnaces. The door jamb assemblies include alternating courses of refractory brick shapes, selected ones of which are fitted with apertures that are aligned as by drilling, when the bricks are installed. One or more steel rods are inserted through the aligned apertures to fasten and retain the bricks in the desired position so as to cooperatively act with the bricks and prevent them from moving when subjected to thermal and mechanical forces encountered in use.
