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 a nozzle of a heating furnace burner. The method comprises the steps that nozzle molds on a burner brick are firstly manufactured; the nozzle molds are arranged at the burner position on a furnace wall during maintenance, corundum mullite castables are poured to a heat storage chamber burner nozzle and the peripheral damaged furnace wall, closing treatment is carried out on the top end closing position and the tail closing position in a high-alumina brick blocking manner, and a separation plate in a heat storage box is repaired through formwork coating materials; and finally, after slurry to be poured is solidified and meets the standard strength requirement, the nozzle molds on the burner brick are demounted, and the nozzle of the burner is molded. Under the condition that the heating furnace burner is damaged, based on the requirement that the nozzle of the burner brick is not changed, the molds are firstly manufactured according to the size of the nozzle of the burner, and then refractory matter is poured to the nozzle to repair the nozzle. The repaired burner is not prone to deforming or collapsing, the service life of the burner on a heating furnace is effectively prolonged, then, construction time is shortened, and the maintenance workload is reduced.

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 bottom and roof of the furnace. After installing and replacing the new burner bricks, formwork will be poured to cast the d...
