Description
Technical field
The present invention relates to a kind of welding procedure controlling grooved crossbeam welding deformation.
Background technology
In 5,000,000 tons of iron and steel bases of certain steel mill are built, No. 1, No. 2 blast funnace hot blast stoves have employed Germany's advanced design technology,
This advanced technology is domestic, and we are that first is introduced.Previous air stove is made up of regenerator, combustor, expansion joint, expands
Joint couples together regenerator and combustor at furnace roof, regulates the displacement expanded with heat and contract with cold by expansion joint, and shortcoming is that expansion joint is easy
Damage.German designs technology is that air stove is supported formed by regenerator, combustor, grooved crossbeam, vault, combustor.Groove
Type crossbeam is connected with regenerator and combustor, and vault is sitting on crossbeam ala lateralis listrium, and vault and crossbeam are coupled together, liquid
Pressure system, at bottom of combustion chamber, drives combustor to move up and down, regulates displacement of expanding with heat and contract with cold.Avoid expansion joint rapid wear
Shortcoming.Germany technology, the world extensively applies.Design requires annular web up and down 2 and vertical rib plate 3 and the outside of grooved crossbeam
Flange plate 4 is welded into grooved in factory, divides 8 sections and dispatches from the factory.Post welding distortion is difficult to control to.
In sum, need a kind of method to complete the control of grooved crossbeam post welding distortion, it is ensured that grooved crossbeam fabricating quality.
Summary of the invention
It is an object of the invention to provide a kind of welding procedure controlling grooved crossbeam welding deformation, grooved crossbeam can be controlled and exist
Welding deformation during assembly welding, it is ensured that the fabricating quality of grooved crossbeam.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of welding procedure controlling grooved crossbeam welding deformation, comprises the following steps:
1) make two pieces of diameters respectively with combustor heading tape, tire board mold that regenerator heading tape diameter is identical；
2) according to the welding sequence drafted, grooved crossbeam is divided watt successively assembly welding on tire board mold.
Described according to the welding sequence drafted, grooved crossbeam is divided watt successively method of assembly welding on tire board mold, its
Welding sequence is as follows:
1) on tire board mold, group is to the annular web up and down of grooved crossbeam and vertical rib plate, and by upper and lower annular web and stud
Plate and tire board mold carry out spot welding；
2) group ala lateralis listrium to grooved crossbeam；
3) grooved crossbeam vertical rib plate and ala lateralis listrium are welded；
4) the outside groove of upper and lower for grooved crossbeam two annular web is welded with ala lateralis listrium；
5) after form removal, mouth in grooved crossbeam ala lateralis listrium is used support；
6) mouth in two annular web being welded with ala lateralis listrium；
7) vertical rib plate is welded with two annular web.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of welding procedure controlling grooved crossbeam welding deformation, first makes tire board mold, then according to reasonably welding is suitable
Sequence is divided watt pre-assembled to grooved crossbeam on tire plate successively and welds, and can control the welding during assembly welding of the grooved crossbeam and become
Shape, it is ensured that the fabricating quality of grooved crossbeam.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail, it should be noted that the enforcement of the present invention be not limited to
Under embodiment.
Embodiment 1: require grooved crossbeam is divided into 8 sections according to design, point watt each building block of making includes: annular web 2,
Vertical rib plate 3, ala lateralis listrium 4.
See Fig. 1, Fig. 2, first make two pieces of tire board molds 1, tire plate thickness of slab δ >=30mm, the diameter of two pieces of tire board molds 1
Identical with combustor heading tape, regenerator heading tape diameter respectively, using tire board mold 1 as the part of housing, by grooved crossbeam
Point on tire plate, watt complete pre-assembled and welding successively.
See Fig. 3, Fig. 4, grooved crossbeam is divided watt successively on tire board mold 1 order of assembly welding as follows:
1) on tire board mold 1, group is to the annular web up and down 2 of grooved crossbeam and vertical rib plate 3, and by upper and lower annular web 2
And vertical rib plate 3 carries out spot welding with tire board mold 1；
2) group ala lateralis listrium 4 to grooved crossbeam is required according to design；
3) grooved crossbeam vertical rib plate 3 and ala lateralis listrium 4 are welded；At this moment ala lateralis listrium 4 welds in free state, only
Can produce cross-direction shrinkage and angular deformation, but ala lateralis listrium 4 thickness is big, rigidity big, angular deformation is the least.
4) the outside groove of upper and lower for grooved crossbeam two annular web 2 is welded with ala lateralis listrium 4；If two annular web 2
Be free state, during welding, cause lower amount of deflection, but now two annular web 2 with tire board mold 1 spot welding, form rigidity
Fixing, just control lower flexure strain.
5) after form removal, the grooved inner mouth of crossbeam ala lateralis listrium 4 is used support, prevent deformation.
6) mouth in two annular web 2 being welded with ala lateralis listrium 4；Now the inner mouth of ala lateralis listrium 4 uses and supports, can
Prevent post welding distortion.
7) vertical rib plate 3 is welded with two annular web 2.It is the least that structure now produces welding deformation.
According to sequence described above, other 7 sections of grooved crossbeam assembly weldings are connected, the welding deformation of grooved crossbeam can be controlled well.
8 sections of grooved crossbeams of assembly welding molding can dispatch from the factory transport to in-site installation.After form removal, at grooved crossbeam ala lateralis listrium 4
In the support that uses of mouth, the effect that sizing supports, therefore grooved crossbeam ala lateralis listrium 4 can be played in the process of transport
In mouth support and when by the transport of 8 sections of grooved crossbeams to Assembling, then to be dismantled.
