Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The specific implementation steps of the online pouring molding method of the heating furnace burner spout of the present invention are:

[0021] Step 1, according to Figure 1-Figure 2 With the structure shown, the nozzle mold 1 on the burner brick is made, wherein the nozzle mold 1 is a horizontally upward oblique cone nozzle model, and is suitable for the size of the nozzle structure on the burner brick. Place a nozzle mold 1 at the nozzle of each burner brick according to the position of the burner brick at the outlet of the original heat storage box 3, and the nozzle mold 1 is inclined outward along the longitudinal central axis of the heat storage box 3, and the range of the inclination angle is 30°-60°, mor...

Abstract

The invention discloses an online pouring molding method for the burner nozzle of a heating furnace. Firstly, the nozzle mold on the burner brick is made, and the nozzle mold is set at the position of the burner on the furnace wall during maintenance, and then the burner nozzle of the regenerator is installed. The damaged furnace wall and the surrounding area are poured with corundum mullite casting material, and at the same time, the closing part of the top and the tail is closed with high alumina bricks, and the partition plate in the heat storage box is covered with formwork. Make repairs. Finally, after the poured slurry is solidified and meets the strength standard requirements, the nozzle mold on the burner brick is removed, and the burner nozzle is formed. In the case of damage to the burner of the heating furnace, based on the requirement that the nozzle of the burner brick remains unchanged, the present invention firstly makes a mold according to the size of the nozzle of the burner, and then repairs it by casting the nozzle with a refractory material. The burner repaired by the invention is not easy to deform and collapse, effectively prolongs the service life of the burner on the heating furnace, and further shortens the construction time and maintenance engineering amount.

Description

technical field [0001] The invention relates to the technical field of regenerative heating furnace equipment, in particular to an online pouring molding method for a burner nozzle of a heating furnace. Background technique [0002] The flame spout of the burner used on the regenerative heating furnace adopts prefabricated burner brick, which is a special sintered body with a large circular nozzle. After a period of use, the burner bricks will be deformed, fall off and collapse, and a large amount of falling off and collapse will seriously affect the heating effect, so the burner bricks need to be replaced. At present, the burner body, heat storage box, burner brick and furnace wall are all built together. To replace the burner, the damaged burner brick and the surrounding furnace wall must be removed. Extend to the expansion joint, up and down to the furnace bottom and furnace roof. After installing and replacing the new burner bricks, formwork will be poured to cast the ...
