Abstract
The invention relates to a method for constructing an expansion joint of a dry quenching furnace. A stainless steel corrugation expansion joint in the traditional design is replaced by a convex expansion joint, and the method includes the following specific steps: (1) a brick carrying steel plate is welded in the direction from a steel beam on the primary dedusting side to the expansion joint; (2) brick carrying steel plates are symmetrically welded in the direction from a lateral steel beam on the dry quenching furnace side to the expansion joint, and expansion joints are reserved between the brick carrying steel plates and the brick carrying steel plate in the step (1); (3) a plurality of layers of ceramic fiber blankets are fixed below the brick carrying steel plates; (4) a convex groove of the convex expansion joint is filled with the ceramic fiber blankets; (5) the upper surfaces of the two sides of the convex expansion joint and the brick carrying steel plates are welded to the steel beam on the primary dedusting side and the steel beam on the dry quenching furnace side for sealing in parallel, and a gap allows the ceramic fiber blanket clamped between the two layers of steel plates to be tightly pressed. Compared with the prior art, the method for constructing the expansion joint has the advantages that the structure is simple, overhauling is conveniently carried out, and the sealing effect and the heat preservation effect can be further improved on the premise that the function of the expansion joint is guaranteed.
Description
Technical field
The present invention relates to the dry furnace apparatus technical field of putting out, relate in particular to a kind of dry stove telescopic joint constructional method of putting out.
Background technology
The dry outlet of still telescopic joint position conventional design of putting out all adopts stainless steel ripple type telescopic joint, in the time that damaging appears in telescopic joint, need to cut stainless steel ripple telescopic joint, then re-start welded seal, welding technique is had relatively high expectations, and sealing is more difficult, easily causes blowby, cause the unstable of dry quenching system pressure, the raising of the burnt rate of restriction responsibility.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of employing simple in structure, overhauls the constructional method of convex telescopic joint easily, under the prerequisite that ensures telescopic joint function, can further improve sealing effect of heat insulation.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of dry stove telescopic joint constructional method of putting out, adopts convex telescopic joint to substitute the stainless steel ripple telescopic joint in traditional design, comprises following concrete steps:
1) the welding holder brick steel plate from one-time dedusting side girder steel to expansion joint direction;
2) be symmetrically welded holder brick steel plate from the dry furnace side girder steel that puts out to expansion joint direction, and and step 1) leave expansion joint between described holder brick steel plate;
3) fixed number layer ceramic fiber blanket below holder brick steel plate;
4) in the tongue of convex telescopic joint, fill up ceramic fiber blanket;
5) convex telescopic joint both sides upper surface is sealed with holder brick steel plate parallel being welded on one-time dedusting and the dry girder steel that puts out furnace side, spacing is as the criterion with the ceramic fiber blanket pressing from both sides between can compacting two-layered steel plates.
Described convex telescopic joint material is plain carbon stool.
Compared with prior art, the invention has the beneficial effects as follows:
1) adopt convex telescopic joint to substitute the stainless steel ripple telescopic joint in traditional design, the structure statement of account, weldability is good, easy to maintenance;
2) in the tongue of convex telescopic joint, fill up ceramic fiber blanket, can strengthen the sealing heat-proof quality of telescopic joint;
3) telescopic joint adopts plain carbon stool to replace stainless steel, and welding is good can be good, facilitates upkeep operation, and investment cost is low.
