Description

Technical Field

[0001] The utility model relates to the technical field of heat storage boxes, in particular to an anchoring structure of a heat storage box and a heat storage box. Background Art

[0002] For a long time, cracks have appeared on the mouth of the heating furnace heat storage box during use, and the cracks gradually expanded and deepened until the refractory material cracked to the steel plate. The cracks here will cause the insulation layer to pulverize and hollow out, the steel structure shell to overheat and burn, shorten the service life of the box, and eventually cause the heat storage box to completely fail to meet the production and use requirements. The high temperature of the box may even damage the furnace wall and surrounding ancillary equipment, causing production to stop, causing the heating furnace to enter the overhaul period ahead of schedule, reducing the production capacity of the heating furnace and causing great economic losses. The traditional heat storage box has a row of anchor nails tilted at 45° welded at the front end of the box. The design intention is to use 45° inclined Y-shaped or V-shaped anchor nails as a stable foundation for the refractory material at the edge of the box mouth. However, because the anchor nails hinder the expansion of the refractory material, the box mouth is severely cracked.

[0003] In response to this problem, the applicant submitted a utility model patent application entitled "A heat storage box anchoring structure" with application number 201721579396.5 in 2017 and was authorized. The technical solution of this patent has solved the problem of refractory cracking to a certain extent and has been widely used in actual production with good anti-cracking effect.
