Technical field
Strip-mill strip roller surface temperature measurement on-line device of the present invention and method of testing thereof, relate to a kind of temperature measurement on-line device for breaker roll surface in plate rolling process of metallurgy industry strip-mill strip production field.
Background technology
At present in strip-rolling process, the heat of rolled piece, the heat of deformation of rolled wire release will make roll heating, and cause roll to expand, it is made in axial direction to produce roll thermal crown, this not only has influence on the strip shape quality of band, and be repeatedly subject to the anxious hot and cold but chilling that causes such as water, air from band due to roller surface, very easily produce fatigue rupture.Therefore, in the operation of rolling, for controlling roller temperature, setting Investigation of Optimum Cooling Condition, grasping the heat be delivered on roll is very necessary with the cooled heat taken away.This just requires that timely breaker roll surface temperature can implement on-line checkingi, to understand the profiling temperatures of roller surface in the operation of rolling more accurately.But in actual production, at present also without setting cooling condition by the method for on-line measurement roller surface temperature.
Traditional roller surface thermometry is that the method rapidly roll being drawn through manual detection carries out line external pelivimetry, then analyzes measurement data, thus improves cooling condition after rolling stops.There is following shortcoming in this mode:
1, measurement result is forbidden, and error is larger;
2, measure after equipment downtime, detect poor in timeliness;
3, analysis result orientation can only improve cooling condition, can not be quantitative;
4, detect by manually participating in completely, efficiency is low.
For problem existing in above-mentioned prior art, a kind of novel strip-mill strip roller surface temperature measurement on-line device of research and design and method of testing thereof, thus the problem existing for overcoming in prior art is very necessary.
Summary of the invention
In view of problem existing in above-mentioned prior art, the object of the invention is a kind of novel strip-mill strip roller surface temperature measurement on-line device of research and design and method of testing thereof.Exist in prior art in order to solve: 1, measurement result is forbidden, and error is larger; 2, measure after equipment downtime, detect poor in timeliness; 3, analysis result orientation can only improve cooling condition, can not be quantitative; 4, detect by manually participating in completely, the problems such as efficiency is low.
