Embodiment Construction

[0024] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0025] A method for manufacturing an anti-deformation water beam in a sintering system, the method comprising the steps of:

[0026] (1) For the upper cover plate 2, lower cover plate 4, two side plates 1 and two end plates 6 that make up the water beam, according to the geometric dimensions required by the drawing, add 4mm of welding shrinkage allowance in the length and width directions ;

[0027] (2) Use a flatbed machine to level the cut upper cover plate, lower cover plate and two end side plates multiple times; the leveling is mainly to eliminate the rolling stress of the plate and the thermal stress generated after being heated during cutting;

[0028] (3) Straighten the channel steel 3 with a jack or a flame; the channel steel is us...

Abstract

The invention relates to a manufacture method of an anti-deformation water beam in a sintering system. The manufacture method comprises the steps that: (1) 4mm welding contraction allowance is respectively added in the length and width directions of an upper cover plate, a lower cover plate, two side plates and two end plates which form a water beam according to the geometric dimension required in a drawing; (2) a flat plate machine is used for flattening; (3) channel steel is aligned; (4) plug welding holes are processed on the water beam; (5) the lower cover plate is firstly fixed on an assembly platform through spot welding, and the water beam is assembled and fixed through spot welding; (6) the upper cover is assembled; (7) the welding formation is carried out; (8) the surface of the water beam after the welding formation is ground, and hydrostatic tests are carried out; and (9) the water beam for completing the hydrostatic tests is subjected to the annealing heat treatment, and the finished product anti-deformation beam is obtained. The manufacture method has the advantages that simplicity is realized, the implementation is easy, the mechanical processing treatment is not needed, the processing time of the water beam is effectively shortened, the production cost is reduced, and the quality is improved. The manufacture method belongs to the safe and reliable manufacture method of the anti-deformation water beam in the sintering system.

Description

technical field [0001] The invention belongs to the field of water beams, in particular to a method for manufacturing anti-deformation water beams in a sintering system. Background technique [0002] The water beam structure of the shaft furnace in the sintering system is mainly a hollow structure surrounded by the upper cover plate, the lower cover plate, two side plates and two end plates. support, and the space separated by the channel steel can also be used as a water channel for the circulation of cooling water. Since the classification of the shaft furnace water beam in the sintering system belongs to the equipment part, it was ordered together with the equipment in the past, although the manufacturing accuracy is high. , but its order cycle is longer and the cost is higher. The main reason is that the technology and quality requirements of the water beam are relatively high. Not only does it need hydraulic pressure test and annealing heat treatment, but after annealin...
