Description
Technical field
The invention belongs to metallurgical technology field, in particular to a kind of mill gap supporting remote dynamic management system.
Background technique
Milling train is the equipment for realizing metal rolled process, refers to and completes stocking to produce the Zhuan Bei ﹐ of overall process to include main
She Bei ﹑ Fu helps She Bei ﹑ handling equipment and auxiliary device etc..Mill gap amount includes 16 contact surfaces and water of down suction
16 contact surfaces in flat gap, mill gap state quality, directly affect the stability of the operation of rolling, and then influence of rolled is set
Standby normal operation and final product quality.The factor that mill gap state is related to includes:
(1) gap between memorial archway window and bearing block；
(2) spatial relation between each relevant surfaces of memorial archway window surface corresponding with bearing block；
(3) surface oneself state, including flatness, the depth of parallelism, verticality etc.；
(4) relative elevation between transmission side and fore side.
Detection for mill gap, current method can only be the detection means traditional by micrometer etc., for rolling
Machine memorial archway window opens a grade size, bearing block width dimensions progress manual measurement to obtain the gap between memorial archway and bearing block
Value.Such as the patent document of Publication No. CN101704189A, disclose " a kind of finishing mill collar assembly and detection method, it is special
Sign is:
(1) collars is installed；Collars on spindle nose, applies axial force to tapered sleeve by tapered sleeve, so that tapered sleeve is generated elasticity and becomes
Shape ensures collars and spindle nose in rolling process without relative displacement；Added axial force is usually 38MPa-40MPa；
(2) detection installation gap；Whether there is gap with the straightway that 0.05-0.10mm clearance gauge detects spindle nose and tapered sleeve, if
Partial plugs are not entered, and are ressembled after need to removing reconditioning deformation point；
(3) spindle nose is detected；With standard tapered sleeve in the case where not filling collars, tapered sleeve is attached on spindle nose to be detected, is pressurizeed
After 20MPa, outer diameter after tapered sleeve deforms is measured in tapered sleeve many places respectively with outside micrometer, is compared, works as mean difference
Reach 0.04mm, it must replacement milling train spindle nose.
... measure outer diameter after tapered sleeve deformation respectively at tapered sleeve 5-6 with outside micrometer, be compared ".It is this
Method haves the shortcomings that following unconquerable:
(1) detection process takes a long time；
(2) detection accuracy is low；
(3) the necessary influence factor of whole needed for cannot detecting above-mentioned gap management process.
As it can be seen that mill gap is managed using existing method, it is relatively low in efficiency.
Meanwhile publication number CN1200963 discloses " a kind of roll seam of milling train used in hot-rolled and cold-rolled flat product
Method of adjustment, this method include the roll-force for measuring the driving side and fore side of each rack, according to driving side and fore side it
Between different roll-forces amendment rolls adjusted value and additional measurement generate in all rolls in rolling along roll mandrel
To each axial force, and with these measured values formed one be used for Roller. redress additional corrections value, wherein the axial force exists
It is to be measured by the load cell being mounted in roller base in each working roll, and is to pass through liquid in the roll of hydraulic adjustment
What the pressure of body measured ".
Publication No. CN1214280 is disclosed " for adjusting rolling for wide metal tape hot mill train or metal tape cold-rolling train
The device (1) of friction ratio between machine base (28) top and bottom rolls (6,7), it includes one and is placed in mill stand (28) introduction side
(27) injection apparatus (2), for spraying a certain amount of liquid along roll gap direction, it also includes a regulating device (3), is used for
It determines the amount of the liquid and is sprayed for adjusting, herein, it is specified that being combined with the practical roll torque of lower roll and/or upper roller pre-
An amount acquire or calculated is used as regulated quantity ".
Summary of the invention
The present invention provides a kind of mill gap supporting remote dynamic management system, to solve mill gap manager in the prior art
Formula Method means fall behind the problem of inefficiency.
A kind of mill gap supporting remote dynamic management system, which includes a data processing platform (DPP), at the data
Platform keeps data transmission, data processing by the mill gap data acquisition device of telecommunication and mill milling production line
The data of the real-time dynamic acquisition mill gap of platform.
After data processing platform (DPP) obtains mill gap data, carry out the following processing:
(1) qualitative analysis judges the as-rolled condition of milling train；
(2) to problematic milling train, live laser detection is carried out, detection content includes the bulk feelings of memorial archway window
Condition, i.e. relative tertiary location, surface slope and flatness；
(3) mill gap is formulated to the testing result in step (2) and adjusts solution, and really for implementing result
Recognize；
(4) Digital evaluation is carried out to the result in step (3) and 3 D stereo visualizes, wherein digitlization is commented
Valence, i.e., with comprehensive score, transposition index index is objective synthetically evaluates rolling state, to replace data point in conventional detection numerous
More, client has no way of grasping the state of equipment precision situation,
3 D stereo visualizes, and is that will test result to show user with the method for three-dimensional diagram, solves conventional inspection
Survey and data dot values be only supplied to the limitation of client, allow user more can direct feel to memorial archway state.
The form intuitively changed most to simplify, most, evaluates testing result and is shown, can solve in conventional detection
