AI Technical Summary

⚠Technical Problem

The corbels in the dry quenching coke oven chute area are prone to wear, deformation and cracks in high temperature environments, causing the annular air duct to sink and reduce the quality of the masonry, affecting the service life.

⚗Method used

Place hard supports between the layers of corbel bricks with the same thickness as the mortar joints. Ensure that the supports are in hard contact with the brick layers to prevent deformation of the mortar joints. Adjust the height of the corbels through supports of different thicknesses. Use heat-resistant stainless steel or hard High quality refractory materials.

🎯Benefits of technology

It effectively prevents the deformation of the ash joints of the corbels and the difficulty of elevation control, improves the masonry quality and service life of the dry quenching coke oven, and enhances production efficiency.

Abstract

The invention relates to a bracket structure for a chute area of a dry quenching furnace. The bracket structure is formed by building a plurality of layers of bracket bricks; and a plurality of supporting pieces are arranged between every two adjacent layers of bracket bricks, the supporting pieces are hard supporting pieces, the thickness of the supporting pieces is the same as that of mortar joints, the top faces of the supporting pieces make direct contact with the upper layer of bracket bricks, and the bottom faces of the supporting pieces make direct contact with the lower layer of bracket bricks. The supporting pieces are placed in the refractory mortar joints between the bracket brick layers, so that the problems of sinking of the annular air duct and cracking of the chute partition wall caused by deformation of the bracket mortar joints and inaccurate bracket elevation control are effectively prevented, the masonry quality of the dry quenching furnace is improved, and the service life of the dry quenching furnace is prolonged.
