Description
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 that is used for plate rolling process breaker roll surface of metallurgy industry strip-mill strip production field.
Background technology
At present in the strip-rolling process, the heat that the heat of rolled piece, deformation of rolled wire discharge will make the roll heating, and cause that roll expands, make it in axial direction produce hot convexity, this not only has influence on the strip shape quality of band, and since roller surface be subjected to repeatedly very easily producing fatigue rupture from the but chilling that causes such as water, air of the anxious hot and cold of band.Therefore, in the operation of rolling, for the control roller temperature, set best cooling condition, it is very necessary grasping the heat that is delivered on the roll and the heat of taking away that is cooled.This just requires timely breaker roll surface temperature can implement online detection, in order to understand the Temperature Distribution situation of roller surface in the operation of rolling more accurately.But in actual production, also do not have at present by on-line measurement roller surface method of temperature and set cooling condition.
Traditional roller surface thermometry is behind rolling stopping, and roll is extracted out carried out the line external pelivimetry by the method for manual detection rapidly, then measurement data is analyzed, thereby is improved cooling condition.There is following shortcoming in this mode:
1, measurement result is inaccurate, and error is bigger;
2, measure behind the equipment downtime, detect poor in timeliness;
3, analysis result can only orientation improve cooling condition, can not be quantitative;
4, detect by artificial the participation fully, efficient is low.
At existing problem in the above-mentioned prior art, research and design a kind of novel strip-mill strip roller surface temperature measurement on-line device and method of testing thereof, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is research and design a kind of novel strip-mill strip roller surface temperature measurement on-line device and method of testing thereof.Exist in the prior art in order to solve: 1, measurement result is inaccurate, and error is bigger; 2, measure behind the equipment downtime, detect poor in timeliness; 3, analysis result can only orientation improve cooling condition, can not be quantitative; 4, detect problem such as efficient is low fully by artificial the participation.
