Problems solved by technology

However, in the known construction methods, the positioning construction is often carried out directly according to the size of the design drawings, and the result is that the positioning welding of the metal tension members has many deviations, and the phenomenon of empty tension is prone to occur.
[0003] Therefore, there are above-mentioned inconveniences and problems in the known annealing furnace furnace wall brick metal drag hook part positioning welding method

Embodiment 1

[0027] see now figure 1 and figure 2 , figure 1 It is a plan layout diagram of the wall brick drawing member of the annealing furnace according to the embodiment of the present invention, figure 2 It is a cross-sectional layout diagram of the first section of the annealing furnace wall brick drag hook part of the embodiment of the present invention. As shown in the figure, the drying section of the annealing furnace is 28m long, the furnace wall is 5.423m high, the supporting brick boards 3 are arranged in three layers, and there are 3340 metal drawing members 4 in total.

[0028] The positioning welding method of metal pull hook parts of annealing furnace wall brick of the present invention is characterized in that it comprises the following steps:

[0029] a. Set masonry datum line and masonry size

[0030] According to the installation drawing of the furnace shell of the annealing furnace, measure the internal space size of the furnace shell, calculate the deviation b...

Abstract

The invention discloses a method for positioned welding an annealing furnace wall brick metal draw hook piece. The method is characterized by comprising the following steps: a, setting laying base line and laying size; b, setting laying mortar joint size; c, setting brick layer line of the draw hook bricks; d, positioning the location of expansion joint; e, positioning the draw hook bricks; f, performing positioned welding on draw hook piece. The method for positioned welding the annealing furnace wall brick metal draw hook piece has the advantages that the phenomenon of sink drawing is prevented, and the positioning accuracy of the metal draw hook piece welding is increased.

Description

technical field [0001] The invention relates to a positioning welding method, in particular to a positioning welding method for metal pull hook parts of furnace wall bricks of an annealing furnace. Background technique [0002] The annealing furnace is a common equipment in the smelting industry. The structure of the furnace wall refractory material of the annealing furnace is mostly a refractory brick structure. The furnace wall refractory bricks are fixed on the furnace wall with metal tension members. See figure 1 , The positioning welding of metal drawing components is very important, which is directly related to the masonry quality of the furnace wall. Usually the height and length direction deviation of the tack welding of the metal drawing member is controlled within ±3mm. However, in the known construction methods, the positioning construction is often carried out directly according to the size of the design drawing, and the result is that the positioning welding of...
