<p>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, which is welded within the refractory lining. This may be done before the refractory lining insulation is installed or alternatively, 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. This permits easy determination of remaining refractory life.</p> |
