Description
Technical field
The invention belongs to equipment of hot rolling fields, are related to one kind applied to the hot rolling of steel industry routine and change endless rolling process
In, the attachment device and system of intermediate base.
Background technique
Conventional panels band hot-tandem unit, which produces, to be rolled with base among monolithic, generally will be through into mm finishing mill unit
Threading is gone through, accelerates rolling, rolling of slowing down, throw the processes such as steel, whipping.In finishing stands, especially ultra-thin gauge rolling when, Yi
Strip head, which bites, between finishing rolling mill is obstructed, and forms piling of steel, skidding and tail portion whipping and folds, and whipping is formed to fold and be bitten, thus
Generate roller surface damage etc.；When take-up because strip front end is snakelike, batches caused by bending etc. and difficult forms piling of steel etc.；Single briquet
Rolling, every piece of strip plate will carry out loading prediction and gap values between rollers setting, if prediction of rolling force is inaccurate, because of prediction of rolling force error meeting
Cause steel strip thickness, convexity to change the plate shape between rack to fluctuate；It is thin to guarantee due to strip rapid heat dissipation in ultra-thin gauge rolling
After belt steel rolling temperature, need to improve threading speed and stable rolling speed as far as possible, but threading speed improves, various threading problems and
Failure rate caused by head folding etc. increases, therefore traditional hot rolling production thin gauge is subject to certain restrictions；In addition, finishing mill volume with
Interval time between volume also influences the performance of milling train production capacity.
Hot-strip endless rolling refers to that piecemeal, a threading do not carry out continuous finish rolling, roll in finish rolling stage rolling blank
Strip afterwards carries out bundling by high-speed flying shear according to required weight.Endless rolling surmounts while solving above-mentioned interruption problems in asymmetic rolling
It is interrupted the limitation of rolling: by solving the problems, such as threading without rolling end to end；Quality stability and lumber recovery are improved by stable rolling；
By reducing threading number and making to batch off time almost nil raising production efficiency；It can produce and surmount limit rolling in the past
The ultrathin strip or wide sheet of size, and by lubrication and rolling and force cold rolling new varieties.Endless Rolling Technology mentions
High strip lumber recovery, size shape precision and the ultra-thin specification ratio of thin gauge realize part " with hot Dai Leng ", reduce roll consumption
It achieves and significantly produces effects.This technology is the primary leap of steel production technology, before representing world today's hot-strip
Along technology.
In Endless Rolling Technology, the interconnection technique of intermediate base is to realize one of the key technology of endless rolling after roughing.
Since mm finishing mill unit uses tension-rolling, can the quality of connection of intermediate base affects endless rolling under Warm status be realized, if even
Overlong time is connect, production efficiency is not only influenced, will also generate obvious temperature drop, subsequent finish rolling is made to be difficult to carry out, if bonding strength is not
High, poor quality, then junction is easy to happen disconnected band, prevents continuous finish rolling from carrying out；And it is unsuitable complicated to connect equipment, otherwise
Can not only equipment installation position be made to be restricted, also will increase investment and production maintenance cost.
Currently, base connection method mainly has pack rolling crimping, docking crimping, welding, machinery even among endless rolling
Connection, reduction flame treatment connection method, direct-electrifying connection method, induction heating connection method and method of laser welding etc..In these companies
It connects in method, reach industrial application has induction heating connection method, laser heating connection method and shearing friction connection method.
Induction heating connection method is the interconnection technique that Kawasaki Steel uses, and this method is will be before preceding slab tail end and rear slab
A minim gap is kept between end, and alternating magnetic field is applied to plate thickness direction in this case, it will be in the binding end of two boards base
Face generates induced current.Slab end face Joule heat due to caused by this induced current and generate heat, heat up, then will combine face pressure
Connect completion connection.This connection method, due in induction heating, flowing through the electric current in made-up belt end corner much smaller than in the middle part of flowing through
Electric current, so that joint face end is remained unbonded portion.Meanwhile the temperature of bonding pad is higher than the temperature of made-up belt other parts, it is strong
Degree is also below other regions, and therefore, bonding pad becomes the weak link during endless rolling, is easy to produce disconnected band.
Laser hot weld connection is that the interconnection technique that Nippon Steel uses can eliminate connecting pin compared with induction heating connection method
Face is not associated with the presence in portion, but still is higher than other positions there are the temperature of engaging portion and is applicable in the limited problem of steel grade；And
And power needed for laser is very big, hence it is evident that increases equipment investment and production cost.
Shearing friction connection method is the cutter using special designing, intermediate base overlap is cut off along inclined-plane, by cutting
It cuts to form two non-oxidation surfaces, shearing force makes newly formed two surfaces that relative motion occur, and rubs, generates big calorimetric
Can, the diffusion on surface is accelerated, pressure is applied to scarf while cutter is sheared and is allowed to form physical bond along shear surface.
This connection method carries out physical connection due to applying pressure to shear surface, is primarily adapted for use in material connection of the same race, material not of the same race
When matter connects, equally exists because chemical component and Physical Metallurgy characteristic are different, the intensity of bonding pad is made to be affected, meanwhile, it should
The problems such as equipment is huge, and occupied space is big, equipment investment and maintenance cost are high.
In short, intermediate base connection type in the prior art, exist big, the intermediate base bonding strength of equipment investment it is not high,
Connection speed is compared with slow, not to be suitable for Dissimilar Steels connection, equipment is huge, one of high these problems of maintenance cost or several
Kind.
