Description
Technical field
The utility model relates to heater for rolling steel equipment technical fields, walk more particularly, to a kind of seamless steel pipe heating furnace
Into beam.
Background technique
Heater for rolling steel is mainly by walking beam heating furnace and pusher-type furnace.Walking beam heating furnace can be to ingredient reality
Now Double-side Heating, its advantages are: haul is flexible, furnace charge all can be discharged when necessary compared with pusher-type furnace up and down
Outside furnace；Weighing area can be evenly heated quickly every breaking into two with one's hands；The arch steel and steel bonding failure of steel-pushing type stove heating are completely eliminated, because
And the length of walking beam heating furnace is made not receive the limitation of these factors, it is achieved the milling train enlargement of rolled pipe, bar.
In turn, the enlargement of milling train, is widely used walking beam reheating furnace.Existing heating furnace walking beam, usually
It is using frame type walking beam, main function is that circulation transports material, in order to make during transporting material, it is heated evenly, then
In the working face of walking beam, upper tooth socket is set, but still there are own shortcomings: 1, own wt weight in this walking beam, support is strong
Degree just has limitation relatively, does not meet theory of mechanics of materials；2, during circulation transports material, although tooth socket can reduce one
The phenomenon that a little uneven heatings, occurs, but effect be not it is very prominent, it is even still to will cause walking beam regional area uneven heating,
Due to hot and cold alternation, it may appear that lead to local deformation, fracture because uneven heating is even.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of mitigation own wt, support strength is improved, and
It can be avoided the even seamless steel pipe heating furnace walking beam happened of uneven heating.
The utility model is the technical scheme adopted is that a kind of seamless steel pipe heating furnace walking beam, including walking beam sheet
Body, the walking beam ontology include upper beam, underbeam and the reinforcing mechanisms being arranged between upper beam and underbeam, and the upper beam includes
Several tooth sockets with arc that upper beam outer surface is arranged in, the reinforcing mechanisms include the vertical reinforcement on several vertical directions
Bottom connection, the other end and the underbeam of muscle, described vertical strengthening ribs one end and tooth socket connect, and the reinforcing mechanisms further include setting
Chiasma type reinforcing rib between vertical strengthening ribs.
The beneficial effects of the utility model are: walking beam using the above structure, compared with the existing technology in frame type
On the one hand walking beam eliminates the support beam and face between upper beam and underbeam, reinforcing mechanisms is arranged between upper beam and underbeam, may be used
To mitigate own wt, on the other hand heat can be allowed to be free to during heating, equably convection current, penetrate, give way
Be uniformly heated into beam, while reducing the negative influence of thermal stress and cool-hot fatigue, prevent walking beam deformation, fracture show
As occurring, the service life of walking beam is improved.
As preferential, upper beam includes that a left part and a right part, the left part and right part are disposed as
Rounded structure substitutes the right-angle structure in original technology using rounded structure, can be damaged to avoid seamless steel pipe, improves nothing
The yield rate of steel pipe is stitched, rejection rate is reduced.
As preferential, several tooth sockets with arc are linked together by arc section, using the structure, are passed through
Arc section links together several tooth sockets, can further strengthen walking beam being heated evenly during transported material
Property.
As preferential, the subtended angle of the tooth socket with arc is 120 degree, and using the structure, subtended angle is 120 degree of tooth socket and object
The contact of material, being heated evenly property are more preferable.
Detailed description of the invention
Fig. 1 is the side view of the utility model and a kind of I-shaped walking beam of heating furnace；
It is as shown in the figure: 1, upper beam；2, underbeam；3, tooth socket；4, vertical strengthening ribs；5, chiasma type reinforcing rib；6, left part；7,
Right part；8, arc section.
Specific embodiment
Utility model is further described referring to the drawings and in conjunction with specific embodiment, to enable those skilled in the art
Refer to the instruction text can be implemented accordingly, and scope of protection of the utility model is not limited to the specific embodiment.
The utility model relates to a kind of seamless steel pipe heating furnace walking beams, including walking beam ontology, as shown in Figure 1, institute
Stating walking beam ontology includes upper beam 1, underbeam 2 and the reinforcing mechanisms being arranged between upper beam 1 and underbeam 2, and the upper beam 1 includes
The tooth socket 3 with arc of several outer surfaces that upper beam 1 is arranged in, the reinforcing mechanisms include vertical on several vertical directions
Reinforcing rib 4, described 4 one end of vertical strengthening ribs is connect with the bottom of tooth socket 3, the other end and underbeam 2 connect, and vertical strengthening ribs are circle
The reinforcing rib of column construction, the reinforcing mechanisms further include the chiasma type reinforcing rib 5 being arranged between vertical strengthening ribs 4, relatively
Walking beam in frame type walking beam in the prior art, the utility model can mitigate own wt, vertical strengthening ribs 4,
Upper beam 1 and underbeam 2 constitute I-shaped structure, and support strength is stronger, and the utility model eliminates between upper beam 1 and underbeam 2
Support beam and face, reinforcing mechanisms are set between upper beam 1 and underbeam 2, heat can be allowed to be free to during heating,
Equably convection current, penetrate, allow walking beam to be uniformly heated, while reducing the negative influence of thermal stress and cool-hot fatigue, prevent
The phenomenon that only walking beam is deformed, is broken, improves the service life of walking beam.
As shown in Figure 1, upper beam 1 includes a left part 6 and a right part 7, the left part 6 and right part 7 are equal
It is set as rounded structure, rounded structure substitutes the right-angle structure in original technology, can be to avoid the rolling under red heat state
Seamless steel pipe scratched by original right angle because intensity is very low when seamless steel pipe is in red heat state, rounded structure
Left part 6 and right part 7 yield rate of seamless steel pipe can be improved, reduce rejection rate.
As shown in Figure 1, several tooth sockets 3 with arc are linked together by arc section 8, pass through arc section 8
Several tooth sockets 3 are linked together, being heated evenly property of walking beam during transported material can be further strengthened.
As shown in Figure 1, the subtended angle of the tooth socket 3 with arc is 120 degree, the tooth socket 3 that subtended angle is 120 degree connects with material
Touching, being heated evenly property are more preferable.
