the refractory layer is formed by bonding and fixing a plurality of refractory bricks, the connection surface between the refractory bricks is an inclined surface, and the inclined surface is provided with a groove tongue structure.
Above-mentioned the utility model has the advantages as follows:
the pouring material is high temperature firing, and inside is mostly grain structure, and the density of resistant firebrick is great than the pouring material, and the briquetting is built by laying bricks or stones, and thermal stability and thermal shock nature are all better. The flame retardant coating is formed by a plurality of resistant firebricks bonding fixedly, and original refractory castable is replaced to monoblock resistant firebrick, can effectively improve the whole thermal shock nature and the stability of flame retardant coating, and is difficult broken, drop, can solve the castable layering, chap, the easy problem that drops, has longer life. And can solve the problem that the new castable and the old castable are peeled off due to poor batch characteristics caused by the coating of the castable during maintenance.
Adopt the fire clay bonding between the resistant firebrick, connect the face and be the inclined plane, and be provided with ditch tongue structure on the inclined plane, ditch tongue structure can increase the bonding face between the brick, still can make and hold back each other between the brick to strengthen the firmness of laying bricks, make it be difficult for dropping. Meanwhile, the inclined plane connecting structure with the groove tongues seals airflow channels between the bricks after daubing the fire clay, can effectively prevent hot airflow from jumping upwards, enhances the heat insulation capability of heat insulation materials, and protects the furnace cover. In addition, the inclined seam with the groove tongue between the bricks can prevent the common problem of fire clay falling of the vertical seam.
