Present apparatus thickness characterization parameter level is divided into two-stage, and level-one includes " maximum thickness ", " thickness average value ", " wedge
Shape ", " convexity ", two level include " thickness minimum value ", " whole plate is poor with plate ".Level-one characterization parameter can be directly used for that main behaviour is prompted to adjust
Whole rolling parameter information assists main behaviour's mill operation；Two level characterization parameter is not directly used to that main behaviour to be prompted to adjust rolling parameter
Information, but can be compared with setting value, it can carry out rolling adjustment by level-one thickness characterization parameter when exceeded.Illustrate such as
Under：
(1) maximum thickness (level-one):When actual (real) thickness maximum value is more than this setting value, terminal prompt
Alarm, and show the overproof amount of thickness, main behaviour adjusts rolling mill screwdown roll gap accordingly, answers plank actual (real) thickness maximum value after rolling
Less than setting value, thick ruler off-gage phenomenon is avoided.
(2) thickness average value (level-one):When actual (real) thickness average value is more than this setting value, terminal prompt
Alarm, and show the overproof amount of thickness, main behaviour adjusts rolling mill screwdown roll gap accordingly, makes plank actual (real) thickness average value low after rolling
In and close to setting value, realize that each plank actual (real) thickness average value of batch production is consistent, and control plank loss of weight client it is expected
Target.
(3) wedge-shaped (level-one):When the practical shim values of plank are more than this setting value, illustrate plank both lateral sides thickness
Pair difference is exceeded, and the alarm of terminal prompt at this time and shows overproof amount, and main behaviour is accordingly adjusted roll gap tuningout, i.e.,
Rolling mill roll fore side and transmission side pressure roll gap difference are adjusted, and reduce plank thickness of two sides difference after rolling, and
Satisfaction≤wedge shape setting value requirement.
(4) convexity (level-one):When the practical convex value of plank is more than this setting value, illustrate plank laterally intermediate ratio two
Side position super thick, the alarm of terminal prompt at this time, and show overproof amount, main behaviour is accordingly adjusted bending roller force, i.e., logical
It crosses and certain external force is applied to roll both sides, change roller curve, plank laterally intermediate and two side position thickness differences are made after rolling
Value is reduced, and meets≤convexity setting value requirement.
(5) thickness minimum value (two level):Under normal circumstances, plank actual (real) thickness minimum value should be greater than setting value, count at this time
Calculation machine terminal can compare actual minimum and setting minimum value, and show difference, for prompting more than main behaviour's plate thickness
Amount；When plank actual (real) thickness minimum value is less than setting value, illustrate that plate thickness is overproof bad, the report of terminal prompt at this time
It is alert, and show overproof amount, plank is downgraded to defective products.
(6) whole plate is poor (two level) with plate:When plank wedge shape, convexity are qualified, but practical whole plate is exceeded with plate difference, meter
Calculation machine terminal notifying is alarmed, and shows overproof amount, and main behaviour is further by the practical convexity of plank, wedge thickness characterization parameter at this time
Roll gap tuningout, bending roller force are adjusted and are rolled, to further decrease convexity and wedge shape, it can be achieved that reducing whole plate with plate difference mesh
, until satisfaction≤whole plate is the same as plate difference setting value.
In conclusion by above functions and approach, the hot rolled plate each position deformation of acquisition is uniform, plate thickness precision
Height, small with plate difference, plate shape is good, realizes this patent intelligence thickness measuring and auxiliary mill operation function.
