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.
Claims23
An interconnected refractory brick door jamb assembly for an electric arc steel furnace comprising:
- (a) a left door jamb assembly and a right door jamb assembly;
- (b) each of said left and right door jamb assemblies comprising a plurality of courses of refractory bricks disposed in successive layers, a brick in each selected course having an aperture therethrough;
- apertures in successive ones of said selected courses being in axial alignment;
- and
- (c) a pair of rods, one of said rods extending within said apertures of said refractory bricks of said left door jamb assembly for strengthening said left door jamb assembly;
- and another of said rods extending within said apertures of said refractory bricks of said right door jamb assembly for strengthening said right door jamb assembly.
A method of making an interconnected refractory brick door jamb assembly for an electric arc steel furnace comprising:
- (a) laying up a left door jamb assembly and a right door jamb assembly each assembly having a plurality of courses of refractory bricks;
- (b) disposing said courses vertically in successive layers;
- (c) drilling aligned apertures within bricks in selected courses of said left door jamb assembly and said right door jamb assembly to produce an aperture extending vertically and in axial alignment through said selected courses of each said left door jamb assembly and said right door lamb assembly;
- and
- (d) installing a first steel rod within said aperture of said left door jamb assembly and a second steel rod within said apertures of said right door jamb assembly.
