ABSTRACT:
A refractory erosion indicator gage for use in blast furnaces and other equipment which require an indication of the erosion wear in the refractory or other lining. The erosion indicator comprises a structural plate member having a configuration preferably triangular. The member is welded within the refractory lining of the equipment in which it is employed. This may be accomplished by welding the plate member to the equipment shell before the refractory lining insulation is installed or alternatively, it may be provided within the refractory lining per se and secured to the shell with the refractory. As the new refractory surface wears or erosion takes place, the exposed portion of the triangle is determinative of the remaining actual thickness of the refractory lining or of the amount of lining eroded away, depending on the orientation of the plate. This permits an easy determination to be made of the remaining refractory life. Thus, the time for replacement of the refractory can be easily determined by visible observation of the indicator or indicators in the equipment internal lining.
