Description
Technical field
The utility model is related to converter accessory technical fields, more particularly to a kind of converter flexural pivot hanging structure.
Background technology
Converter installation is a kind of important core equipment of steel mill, and single seat mammoth conveter gross mass is up to 2000 tons or more.
It when converter operates, needs to fascinate rolling as low speed, this makes converter and support backing ring generation frictional rotation.In actual production, converter
In the roll procedure that fascinates, inclination angle occurs intermittent friction abnormal sound and with slight vibration when being more than 60-70 °, inclination angle is more than
Can gradually it aggravate after 120 °, it is most apparent when close to 180 °.This abnormal sound and vibration can generate gap and be rubbed with block seat contact surface
It wipes, seriously affects converter riding quality and increase maintenance.
Utility model content
The purpose of this utility model is to provide a kind of converter flexural pivot hanging structure, has the contact surface of hardening, reduces and rub
The damage of wiping, extends service life.
To achieve the above object, the utility model provides a kind of converter flexural pivot hanging structure, including suspending assembly, described
One end of suspending assembly is connected in converter, and the other end is connected on backing ring, and the suspending assembly includes first lug, second
Lug and connecting rod, the first lug are connected with second lug by the connecting rod, the first lug and the connecting rod
Between, connected by ball hinge between second lug and the connecting rod, the ball valve seat includes valve seat and valve head, described
The contact surface of valve seat and the valve head is spherical structure, and the spherical structure includes hardened layer and ductile layers.
Preferably, it is accompanied by the hardened layer with the oxide layer for reinforcing abrasion protection.
Preferably, the surface of hardened layer is equipped with high temperature wear resistant alloy coating, and the thickness of the high temperature wear resistant alloy layer is not small
It is not less than 56 in 0.5mm, hardness HRC.
Preferably, the backing ring is used to support the converter, and the suspending assembly is around the converter.
Preferably, the suspending assembly is distributed along the even circumferential of the converter.
Therefore, the converter flexural pivot hanging structure of the utility model using the above structure has the contact surface of hardening, reduces
The damage of friction, extends service life.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model converter flexural pivot hanging structure embodiment；
Fig. 2 is the schematic diagram of ball hinge embodiment in the utility model converter flexural pivot hanging structure；
Wherein：1, converter；2, suspending assembly；3, hardened layer；4, ductile layers.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, a kind of converter flexural pivot hanging structure, including suspending assembly 2, circumference of the suspending assembly 2 along converter
It is uniformly distributed.Converter is equipped with backing ring, and backing ring is used to support converter.One end of suspending assembly 2 is connected in converter, the other end
It is connected on backing ring.Suspending assembly 2 includes first lug, the second lug and connecting rod, and first lug and the second lug pass through connecting rod
Connection.It is connected by ball hinge between first lug and connecting rod, between the second lug and connecting rod.Ball valve seat includes valve seat and valve
The contact surface of head, valve seat and valve head is spherical structure, and spherical structure includes hardened layer 3 and ductile layers 4.Hardened layer 3 is located at tough
Property layer 4 upper layer, hardened layer 3 is the structure that is formed after quenching of ductile layers 3, strengthens the hardness on spherical structure surface.Firmly
The combined use for changing layer 3 and ductile layers 4 can increase wear-resistant strength when ball hinge effect.It is tough in continuous friction process
Property layer 4 deformed upon under the action of powerful, hardened layer 3 improve ductile layers 4 wear-resistant strength, place ductile layers 4 occur it is big
Deformation.The oxide layer having for reinforcing abrasion protection is accompanied by hardened layer 3, oxide layer can delay the degree of wear.Hardening
The surface of layer 3 is also an option that equipped with high temperature wear resistant alloy coating, thickness >=0.5mm of high temperature wear resistant alloy layer, 62 >=hardness
HRC >=56, to enhance the wear-resistant strength of ball hinge.
During converter rotates, valve head rotates with valve seat in ball hinge.The surface of valve head and valve seat is ball
Face structure, the overlay cladding initial hardness of valve head sealing surface is softer, plasticity and toughness are high, and the hardness on sealing surface surface layer increases after hardening treatment
Add, but the secondary surface layer still plasticity and toughness of sealing surface are higher, in operation process, when being impacted, this valve head built-up welding sealing
Face is not susceptible to be broken.
Therefore, the converter flexural pivot hanging structure of the utility model using the above structure has the contact surface of hardening, reduces
The damage of friction, extends service life.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than limits it
System, although the utility model is described in detail with reference to preferred embodiment, those skilled in the art should manage
Solution：It can still be modified or replaced equivalently the technical solution of the utility model, and these are changed or equally replace
Change the spirit and scope that cannot also make modified technical solution be detached from technical solutions of the utility model.
