Description

Technical Field

[0001] This utility model relates to the field of heating furnace construction technology, specifically to a heating furnace regenerative burner nozzle mold. Background Technology

[0002] A heating furnace is a thermal device used to heat steel billets during steel rolling or forging, typically operating at temperatures between 1300 and 1400°C. With the development of the steel industry, heating furnaces are increasingly trending towards larger sizes, lower energy consumption and pollution-free operation, leading to increasingly stringent requirements for furnace lining materials. The quality of furnace lining directly affects its service life, thermal efficiency, and production safety. High-quality lining ensures the stability and durability of the heating furnace under high-temperature conditions, reduces heat loss, improves thermal efficiency, and thus lowers energy consumption and production costs.

[0003] For example, Chinese patent document CN104154756B discloses a method for integral casting of furnace walls in a heating furnace. This method includes the following steps: 1. Installing burner bricks; 2. Setting up a connecting structure on the furnace wall steel plate, constructing the furnace wall insulation layer, and installing furnace wall anchor bricks, exposing the connecting structure; 3. Erecting a casting template, detachable connecting components passing through the casting template and detachably connecting them to the connecting structure, and detachably connecting the expansion joint plate to the detachable connecting components; 4. Casting the furnace wall, injecting the castable refractory between the casting template and the furnace wall insulation layer, and removing the detachable connecting components before the castable refractory initially sets and after it has stabilized the expansion joint plate; 5. Demolding, completing the furnace wall casting. This method enables integral, one-time casting of the furnace wall refractory, simplifying the construction process and improving construction quality. The method is simple to implement, fast, and the cast furnace wall refractory meets production needs.

[0004] However, the above method also has certain drawbacks: the joint between the nozzle and the heat storage box is a secondary splicing during the construction process, and the gap between the joint surfaces is large, which can easily cause problems such as poor sealing of the furnace wall and fire leakage, which in turn leads to a decrease in the heat storage capacity of the heating furnace and even reduces the service life of the heating furnace. Utility Model Content

[0005] This utility model provides a heat storage burner nozzle mold for a heating furnace to solve the technical problem that the poor connection between the nozzle and the heat storage box in the existing heating furnace masonry structure leads to a decrease in the heat storage capacity of the heating furnace or even a reduction in the service life of the heating furnace.

[0006] To solve the above problems, the present invention provides a heating furnace regenerative burner nozzle mold with the following technical solution:

[0007] A heat storage burner nozzle mold for a heating furnace includes a heat storage box, with a nozzle mold provided on one side of the heat storage box. The side where the nozzle mold is located is defined as the right side. The nozzle mold is made of foam material and has the same shape and size as the burner. Both the outer side of the heat storage box and the right side of the nozzle mold are provided with vertically extending templates for fixing the nozzle mold. Castable material is provided between the two templates.

[0008] Its beneficial effects are as follows: by setting the nozzle mold made of foam material, the nozzle of the furnace wall after casting can be tightly fitted with the heat storage box, avoiding the situation where the performance of the heating furnace is affected due to the poor splicing of the nozzle and the heat storage box. At the same time, the use of nozzle mold can shorten the installation time of the heat storage box and improve the construction efficiency of the heating furnace.

[0009] Furthermore, a plurality of connecting screws extending to the left and right are provided between the two templates, and the connecting screws are fixedly connected to the two templates to maintain the distance between the two templates during casting.

[0010] Furthermore, a burner brick is provided on the right side of the nozzle mold, and the size of the burner brick matches the size of the nozzle mold.

[0011] Furthermore, the nozzle mold is provided with a fixing rod for fixing the nozzle mold, and the fixing rod is fixedly connected to the right template to prevent the nozzle mold from shifting during casting.

[0012] Its beneficial effects are: the setting of the fixing rod avoids the displacement of the nozzle mold due to the impact of the pouring material during the pouring process, thus improving the construction quality of the heating furnace.

[0013] Furthermore, the nozzle mold is made of polystyrene foam to provide good support during casting.

[0014] Furthermore, the heat storage box is a rectangular box, and the right end of the heat storage box has a fixing groove for fixing the nozzle mold.

[0015] Furthermore, the castable is corundum-mullite castable.

[0016] The beneficial effects of the regenerative burner nozzle mold for a heating furnace provided by this utility model are:

[0017] 1. By setting up a nozzle mold made of foam material, the nozzles of the furnace wall after casting can fit tightly with the heat storage box, avoiding the situation where the performance of the heating furnace is affected due to the poor splicing of the nozzles and the heat storage box. At the same time, the use of nozzle molds can shorten the installation time of the heat storage box and improve the construction efficiency of the heating furnace.

[0018] 2. The installation of the fixing rod prevents the nozzle mold from shifting due to the impact of the pouring material during the pouring process, thus improving the construction quality of the heating furnace. Attached Figure Description
