AI Technical Summary
In the existing fused brick production process, the furnace mouth needs to be opened frequently when taking out and putting in the fused bricks after insulation and heating, which causes heat loss and shortens the service life of the kiln. In addition, shrinkage holes are easily generated inside the fused bricks, leading to abnormal erosion.
An electric fused brick insulation box was designed, which included a discharge bracket, a sealing plate and a sealing door. The discharge bracket was used to place electric fused bricks in the box, and the opening of the insulation heating chamber was sealed by the sealing plate. Combined with the insulation material filling layer and the cold iron block, heat loss and shrinkage cavity formation were reduced.
It realizes convenient loading and unloading of fused bricks, reduces heat loss, prolongs the high-temperature shrinkage compensation time of fused bricks, reduces shrinkage holes, and increases the service life of the kiln.

Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of electrically fused brick, specifically to electrically fused brick heat preservation box. BACKGROUND
[0002] The production process of electrically fused zirconia alumina is to pour the molten liquid which is clarified in the electric arc furnace into the previously formed sand mold, and then process the product into the product by using diamond abrasive tools after cooling, annealing and heat preservation. The large AZS electrically fused brick is widely used in the pool wall part of the glass furnace which contacts with the glass liquid. The service temperature of this part is above 1500 DEG C, and the service life is required to be more than 6 years. Moreover, it is subjected to the erosion of the glass raw material. Therefore, if there is a shrinkage cavity in the product, abnormal corrosion will occur in this part, which will shorten the service life of the glass furnace. However, the solidification of the molten liquid of the electrically fused brick is a layer-by-layer solidification, which is solidified from bottom to top and from outside to inside. The shrinkage cavity formed in the cooled part is filled with the molten liquid provided by the high temperature position. However, the riser part which provides the molten liquid for supplementing is also cooled from outside to inside in the production of the electrically fused brick. Therefore, the effect of supplementing is limited, and it is easy to produce a shrinkage cavity in the large AZS electrically fused brick, which will cause abnormal corrosion in use, affect the service life of the furnace, and even cause production accidents.
[0003] Moreover, and most importantly, in the process of taking out the electrically fused brick which is heated by heat preservation, the furnace opening needs to be opened, and it takes a long time to take out the electrically fused brick, which causes the furnace opening to be opened frequently. Moreover, in the process of placing the new electrically fused brick which is not heated into the furnace, the furnace opening is also opened frequently, which causes the heat in the furnace to be lost.
