Combined building brick capable of judging thickness of ladle bath

Abstract

The invention discloses a combined building brick capable of judging the thickness of a ladle bath. The combined building brick comprises a building brick built in an inner heat insulation wall of a cylindrical ladle, wherein a cavity is formed in the end, facing the outer side of a furnace, of the building brick; an identification brick is embedded into the cavity. The combined building brick has the advantages of simplicity in mounting, low cost, remarkable warning mark and the like; the identification brick is made from a material different from that for the building brick, blackness coefficients of the identification brick and the building brick are greatly differed, and when the building brick is over-fired to expose the identification brick, the brightness of the building brick is greatly different from that of the identification brick, and a remarkable color change can be produced, so that the over-firing degree of the building brick can be intuitively judged, misjudgment is avoided, the ladle can be actually safely transferred, safety accidents are prevented, and the service life of a refractory material is fully utilized.

Description

technical field [0001] The invention relates to the field of fire-resistant and heat-insulating materials, in particular to a combined masonry brick for judging the thickness of a ladle molten pool. Background technique [0002] Steel drums, commonly known as ladles or large tanks, are generally used to hold and transport molten steel. When the ladle is in use, a layer of heat insulation material will be built along the wall of the cylinder to form a heat insulation slag line, and masonry bricks are generally used. However, in the current ladle use process, the degree of erosion of ladle masonry bricks is basically judged by the operator's naked eyes through experience, and there is no practical and effective identification method. In this way, the error in judging the residual thickness of the ladle with the naked eye is relatively large, resulting in the inability to accurately judge the degree of erosion of the ladle masonry bricks. It goes offline before reaching the s...
