Abstract
The utility model provides a novel double-fin profiled wall steel pipe and a membrane type water cooled wall made of the same. The double-fin profiled wall steel pipe comprises a profiled wall steel pipe and two fins, and is characterized in that: the steel pipe and the fins have an integrated structure which is extruded simultaneously in a hot extrusion mode, and the profiled wall steel pipe has an eccentric structure or a structure that half-amplitude of steel pipe wall is thick. The membrane type water cooled wall is characterized by being formed by welding the fins of a plurality of double-fin profiled wall steel pipes; and during installation, one side of the thick wall of each steel pipe is arranged on the fire facing surface of a boiler. The novel double-fin profiled wall steel pipe and the membrane type water cooled wall made of the double-fin profiled wall steel pipe achieve the effects of reducing welding workload, avoiding the increase of steel pipe stress, the change of tissue metallographic phases and the deformation of the steel pipes due to high temperature during welding and prolonging the service life of the steel pipes by distributing the wall thicknesses of the steel pipes reasonably.
Description
Technical field
This is suitable for novel a kind of special-shaped wall steel pipe and a kind of fin panel casing of belonging to, and is specially a kind of pair of fin abnormity wall steel pipe and by its fin panel casing of processing.
Background technology
Fin panel casing is widely used by large-sized boiler, and it is made up of light pipe and band steel, and band steel both sides and steel pipe are welded.During making, every steel pipe needs and the welding of band steel both sides, and the high temperature during welding is prone to cause the stress of steel pipe to increase, organizes metallographic to change or pipe deformation.
The patent No. is that ZL201020570681.2 has announced a kind of pair of fin steel pipe and by its fin panel casing of processing; Can overcome the influence of welding to steel pipe; The patent No. is that ZL201020575467.6 has announced a kind of wear-resisting eccentric pipe fin panel casing; Through the off-centre design, can make fin panel casing more wear-resisting, thereby prolong the service life of fin panel casing.
Summary of the invention
The utility model provides a kind of novel two fins abnormity wall steel pipes and by its fin panel casing of processing, and purpose is to reduce the welding job amount, stop because the steel pipe stress that the high temperature during welding causes increases, organizes metallographic variation, pipe deformation and increase service life of steel pipe through the reasonable distribution thickness of steel pipe.
In order to achieve the above object, the utility model adopts following technical scheme.
A kind of pair of fin abnormity wall steel pipe, it comprises special-shaped wall steel pipe and two fins, it is characterized in that steel pipe and fin are the integrative-structures of extruding simultaneously through the mode of hot extrusion, and special-shaped wall steel pipe has eccentric structure or the thicker structure of half range steel pipe walls.
A kind of fin panel casing is characterized in that it is that fin with some above-mentioned pair of fin abnormity wall steel pipes is welded, and the side that thickness of steel pipe is thicker is installed on the side towards the fire of boiler during installation.
In sum, the utility model compared with prior art has the following advantages.
1, compare with existing fin panel casing, existing fin panel casing is to wait the steel pipe and the band steel of wall thickness to be welded, and described pair of fin abnormity of the utility model wall steel pipe is to produce through the mode of hot extrusion; Its special-shaped wall steel pipe and fin are structure as a whole; Saved half the welding job amount when making fin panel casing, can not cause the stress of steel pipe to increase, organize metallographic to change or pipe deformation, in addition; Because the thicker side of the utility model thickness of steel pipe is installed on the side towards the fire of boiler; Under the equivalent weight prerequisite, can make fin panel casing more wear-resisting, thereby prolong the service life of fin panel casing.
2, be that a kind of pair of fin steel pipe that ZL201020570681.2 announces compared with the fin panel casing of being processed by it with the patent No.; It is to wait wall thickness steel tube; The side that the utility model thickness of steel pipe is thicker is installed on the side towards the fire of boiler; Under the equivalent weight prerequisite, can make fin panel casing more wear-resisting, thereby prolong the service life of fin panel casing.
3, be that ZL201020575467.6 has announced that a kind of wear-resisting eccentric pipe fin panel casing compares with the patent No.; It is through being welded; Described pair of fin abnormity of the utility model wall steel pipe is to produce through the mode of hot extrusion; Its special-shaped wall steel pipe and fin are structure as a whole, and have saved half the welding job amount when making fin panel casing, can not cause the stress of steel pipe to increase, organize metallographic to change or pipe deformation.
