Description
Technical field
A kind of device that Shape correction is carried out to the flat volume of coils of hot-rolled steel is the utility model is related to, belongs to coils of hot-rolled steel production and sets
Standby technical field.
Background technology
On hot rolling production line and coil of strip it is offline after, often occur due to flat volume phenomenon caused by a variety of causes, mainly go out
On the present steel grade such as high-carbon steel and limit thin checkered plates, it is generally the case that when coil of strip internal diameter is less than 690 millimeters, downstream is opened
Straight snips the production line such as cuts and is unable to uncoiling, causes coil of strip to scrap.Even if the less serious coil of strip of some flat volumes can inadequate uncoiling,
There is shape wave after uncoiling being caused because shape is irregular and side sway is serious, can only do and sentence useless processing, have a strong impact on the life of user
Efficiency is produced, adds production cost.
Therefore, multiple manufacturing enterprises solve the problems, such as flat volume by improving technological parameter and the equipment of hot rolling production line.
Chinese patent CN1506174A discloses a kind of method for coiling for preventing the flat volume of hot-strip, and phosphorus content is more than
0.25Wt% strip shuts out from finishing mill and batched after section cooling into coiling machine, and its oiler temperature control is in phase
Temperature Ar1+ (- 10 DEG C~+60 DEG C) scope, makes the core that the phase transformation of coil of strip contacts from outer layer and with reel to intermediate layer
Progressively carry out.
Chinese patent CN102335681 A disclose a kind of method for coiling for preventing the flat volume of hot-strip, and this method includes
Two stages：First stage：Strip shuts out from finishing mill and batched after section cooling into coiling machine, obtains coil of strip,
Wherein coiling temperature is 500 DEG C~600 DEG C；Second stage, the coil of strip after batching is stopped on coiler mandrel 20s~
60s。
Chinese patent CN201150959Y discloses a kind of four wedge full circle reels of power reel, including mandrel, master
Axle, contract cylinder, secter pat, what this reel was made up of provided with one contract cylinder, mandrel, main shaft, internal layer wedge and outer layer wedge
Breathing mechanism.

There is the problem of flat volume in thin checkered plates etc..Chinese patent CN201150959Y is related to special equipment, adds and is produced into
The problems such as this and equipment are taken up an area, certain practical operation problem be present.
Also some manufacturing enterprises solve the problems, such as the offline flat volume occurred of coil of strip by using special equipment.
Chinese patent CN200940057Y discloses a kind of Manual expanding roll device for metal band roll, including pull bar, with
The be hinged cam handle of pull bar left end, a splicing sleeve is set with the left part of pull bar, is combined with a spiral shell in the right part of pull bar
Line splicing sleeve, one end of three pairs of connecting rods are respectively hinged on splicing sleeve and screw thread splicing sleeve, the other end and branch per a pair of links
Supporting block is hinged；The cam portion of cam handle and the end face of splicing sleeve abut.The patent has the coiled material for volume phenomenon of collapsing by swelling
Internal diameter, prevents collapse volume and inner ring pine layer, and cam handle can realize quick swelling with taking out when pulled；Operation of cam handle is turned
Swelling energetically can be realized with taking out when dynamic.
Prevent flat volume problem from occurring using above-mentioned plant equipment, be related to special equipment, add production cost, and deposit
In certain unknown safety problem, there is certain difficulty in practical operation.
