Embodiment Construction

[0025] The specific implementation steps of molding method of the present invention are:

[0026] 1. According to figure 1 , figure 2 For the structure shown, the cross ribs and burner nozzle molds are made respectively. Among them, the cross rib 1 is a cross-shaped support frame used to support the mold of the burner nozzle, that is, it is placed in the outlet of the burner heat storage box, and the outlet of the heat storage box is divided into four equal parts. Each part Place a burner nozzle mold. The burner spout mold is formed on a rectangular mold base plate 2 with four spout models 3 protruding outward from the plate surface of the mold base plate. The nozzle model 3 on the mold base plate 2 is preferably made into a horizontal oblique cone ( image 3 ), that is, the spout model 3 is inclined to one side in the horizontal direction. Such as Figure 5 As shown, the layout of the nozzle mold of the burner is to make the nozzle model 3 tilt outward along the longit...

Abstract

The invention relates to an integral casting-molding method for a heat-storing type heating-furnace burner, which comprises the following steps of: firstly manufacturing cross reinforcing ribs and a burner-spout mould, then arranging a burner body and a heat-storing box, installing the cross reinforcing ribs and the burner-spout mould at an outlet of the heat-storing box, arranging a template forsupporting an inner wall surface on the inner surface of a furnace wall, carrying out integral casting for a wall-body space in the template and the burner-spout mould through a slurry material, dismantling the template for supporting the inner wall surface and the burner-spout mould after the slurry material is solidified and the requirements of an intensity standard are met, and molding a burner spout to form the integral burner together with the burner body and the heat-storing box fixed on the furnace wall of a heating furnace. Through the integral casting-molding method for the heat-storing type heating-furnace burner, the defects of long period, complex construction and high cost of a traditional process are overcome, the service life of the burner on the heating furnace is effectively prolonged, the construction time and the maintenance-engineering quantity are shortened, and the integral casting-molding method is a maintenance-construction method which has the advantages that the time is saved, the labor is saved, the cost is effectively lowered, and the service lives of the heating furnace and the burner are prolonged.

Description

technical field [0001] The invention relates to the masonry of a regenerative heating furnace, in particular to an integral pouring molding method for the burner of the regenerative heating furnace. Background technique [0002] The burner on the regenerative heating furnace includes the burner body, the heat storage box and the burner brick. The burner brick is a special sintered body with a large circular nozzle. During the masonry process of the regenerative heating furnace, the installation and construction method of the burner is basically to install the burner body, the heat storage box and the finished burner brick on the masonry furnace wall. The body, heat storage box and burner bricks are built together with the furnace wall. In the process of using the heating furnace built by this traditional process, when the burner brick is damaged and needs to be repaired, the damaged burner brick and the surrounding furnace wall must be removed first. Seam, extending up and...
