Description
Technical field
The invention belongs to equipment of hot rolling field, it is related to one kind to be applied to steel industry routine hot rolling and changes endless rolling process
In, the attachment means and system of middle base.
Background technology
Conventional panels band hot-tandem unit is produced and rolled with monolithic centre base, typically will be through into mm finishing mill unit
Threading is gone through, accelerated rolling, rolling of slowing down, thrown the processes such as steel, whipping.In finishing stands, particularly ultra-thin gauge rolling when, Yi
Strip head is nipped and is obstructed between finishing stand, is formed piling of steel, is skidded and the folding of afterbody whipping, and whipping forms folding and nips, so that
Produce roller surface to damage etc.；Batch when take-up because strip front end is snakelike, caused by bending etc. and difficult form 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
Plate shape between belt steel thickness, convexity change and frame is caused to fluctuate；It is thin to ensure due to strip rapid heat dissipation in ultra-thin gauge rolling
Belt steel rolling temperature, need to as far as possible improve threading speed and stable rolling speed, but threading speed improve after, various threading problems and
The fault rate that head folding etc. causes increases, therefore traditional hot rolling production Thin Specs are subject to a definite limitation；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, in finish rolling stage rolling blank not piecemeal, a threading, to carry out continuous finish rolling, is rolled
Strip afterwards carries out bundling according to required weight by high-speed flying shear.Endless rolling surmounts while above-mentioned interruption problems in asymmetic rolling is solved
It is interrupted the limitation of rolling：Threading is solved the problems, such as by without rolling end to end；Quality stability and lumber recovery are improved by stable rolling；
By reducing threading number of times and making to batch off time almost nil improve production efficiency；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, carries
Strip lumber recovery high, size shape precision and the ultra-thin specification ratio of Thin Specs, realize part " with hot Dai Leng ", reduce roll consumption
Achieve and significantly produce effects.This technology is the once leap of steel production technology, before representing world today's hot-strip
Along technology.
In Endless Rolling Technology, after roughing in the middle of the interconnection technique of base be to realize one of the key technology of endless rolling.
Can the quality of connection of middle base affects endless rolling because mm finishing mill unit uses tension-rolling, under Warm status realize, if even
Overlong time is connect, production efficiency is not only influenceed, obvious temperature drop will be also produced, follow-up finish rolling is difficult to, if bonding strength is not
High, poor quality, then junction be susceptible to broken belt, prevent continuous finish rolling from carrying out；And it is unsuitable complicated to connect equipment, otherwise
Equipment installation site can not only be restricted, can also increase investment and production maintenance cost.
At present, base connection method mainly has ply rolling crimping, docking crimping, welding, machinery even in the middle of endless rolling
Connection, reduction flame treatment connection method, direct-electrifying connection method, sensing heating connection method and method of laser welding etc..In these companies

Sensing heating connection method is the interconnection technique that Kawasaki Steel uses, and the method is by before preceding slab tail end and rear slab
A minim gap is kept between end, alternating magnetic field is applied to thickness of slab direction in this case, will be in the binding end of two boards base
Face produces induced-current.Joule heat that slab end face is caused due to this induced-current and generate heat, heat up, then will be with reference to face pressure
Connect completion connection.This connection method, due in sensing heating, flowing through the electric current in made-up belt end corner much smaller than in the middle part of flowing through
Electric current, joint face end is remained uncombined portion.Meanwhile, the temperature of the temperature higher than made-up belt other parts of bonding pad, its is strong
Spend also below other regions, therefore, bonding pad turns into the weak link during endless rolling, easily produces broken belt.
LASER HEAT welding is the interconnection technique that Nippon Steel uses, and compared with sensing heating connection method, can eliminate connection end
The presence in the uncombined portion in face, but still there is the temperature of joint portion higher than other positions, and it is applicable the limited problem of steel grade；And
And power is very big needed for laser, hence it is evident that increase equipment investment and production cost.
Shearing friction connection method is, using the cutter of particular design, middle base overlap to be cut off along inclined-plane, by cutting
Cut to form two non-oxidation surfaces, shearing force makes two surfaces of new formation that relative motion to occur, and rubs, and produces big calorimetric
Can, the diffusion on surface is accelerated, applying pressure to scarf while cutter is sheared 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 is connected, equally exist because chemical composition and Physical Metallurgy characteristic are different, the intensity of bonding pad is affected, meanwhile, should
Equipment is huge, the problems such as big, equipment investment and the maintenance cost high of taking up room.
In a word, middle base connected mode of the prior art, exist big, the middle base bonding strength of equipment investment it is not high,
Connection speed is huge compared with slow, not to be suitable for Dissimilar Steels connection, equipment, the one kind or several in maintenance cost these problems high
Kind.
