Abstract
The utility model provides a temperature detecting and controlling device for a steel plate in a front heating area of a continuous annealing furnace. A pyrometer additionally arranged at an outlet of a heating section is connected with a primary PLC (Programmable Logic Controller) of a furnace area through an analog quantity acquisition plate; and the primary PLC is respectively connected with a secondary PLC of the furnace area and a human-machine interface, wherein a heating parameter given program is programmed in the secondary PLC; and the human-machine interface is provided with manual keys. The pyrometer not only can be used for accurately detecting the temperature of the plate, but also can be used for correcting a furnace temperature controller; the primary PLC of the furnace area can closely adjust and control the temperature of the furnace; the secondary PLC of the furnace area takes the temperature detected by the pyrometer and the outlet temperature of a soaking section as the target set temperature, thereby ensuring that the steel plate is uniformly heated in the furnace and preventing the deviation and the heat gauffer; and an operator can monitor a signal for the temperature of the plate through the human-machine interface and intervene the set value of the temperature through the manual keys, thereby greatly improving the precision for detecting and controlling the temperature of the plate and laying a foundation for developing and producing novel products.
Description
Technical field
The utility model belongs to automatic detection and control system, particularly a kind of detection control apparatus that is used for cold rolled continuous annealing stove heating proparea steel billet temperature.
Background technology
The intrinsic bringing-up section of heating system in certain cold rolling mill continuous annealing furnace district and soaking zone all adopt the radiant tube heating, and combustion gas produces heat in the radiant tube internal combustion, passes to belt steel surface by M shape radiant tube and heats.Transmission and fore side 374 radiant tubes that distributing symmetrically at stove, bringing-up section has 12 districts, the 1-8 district is the proparea, the 9-12 district is the back zone, per two shared temperature controllers in district, measure furnace temperature by the thermopair that is installed on the furnace shell, other has 5 pyrometers to measure steel billet temperature, and the plate temperature fed back to stove district I and II furnace temperature programmable logic controller (PLC), the plate temperature that receives is handled, according to result furnace temperature is regulated, make the band steel evenly be heated to target temperature in bringing-up section.
Because former design is that the 1-8 district is not provided with pyrometer in the bringing-up section proparea, therefore can't accurately detect the temperature of steel plate in the heating proparea, for plate temperature control bring many unfavorable: the one, can't to the heating proparea belt steel temperature accurately control, also just can't guarantee the annealing performance of steel plate; The 2nd, can't guarantee the homogeneity that steel plate is heated in the heating proparea, cause steel plate hot gauffer phenomenon to occur easily at bringing-up section sideslip or steel plate; The 3rd, can't guarantee the accuracy that mathematical model drops into, make steel plate occur owing to anneal or cross the situation of annealing easily, directly have influence on the usability and the up-to-standard rate of steel plate.
Summary of the invention
The purpose of this utility model aims to provide a kind of can accurately the detection and heats the proparea steel billet temperature, and steel billet temperature is accurately controlled, thereby prevents the detection control apparatus of sideslip and hot gauffer defective.
For reaching this purpose, the utility model has been taked following solution:
A kind of continuous annealing furnace heating proparea steel billet temperature detection control apparatus, comprise that stove district I and II furnace temperature programmable logic controller is PLC, be characterized in, the place installs a pyrometer at continuous annealing furnace heating one section outlet, pyrometer connects stove district primary PLC by the analog acquisition plate, and primary PLC has the stove region two-stage PLC of heating parameters preset sequence to be connected with the man-machine interface that is provided with manual button with establishment respectively.
Owing to set up pyrometer in the heating proparea, in the plate temperature Furnace Temperature Controller revised accurately detecting herein; Stove district primary PLC is responsible for plate temperature signal is handled, and in view of the above furnace temperature is carried out closed loop adjustment and control; Stove region two-stage PLC heating parameters preset sequence as the Target Setting temperature, calculates this temperature and soaking zone outlet temperature also control stove district primary PLC and carries out the temperature adjustment, to guarantee steel plate being heated evenly in burner hearth, prevents to produce sideslip and hot gauffer; The operative employee can monitor plate temperature signal by man-machine interface, and can click manual button and intervene desired temperature; The annealing process aspect also can utilize this pyrometer as the technology controlling and process point, guarantees the steel plate annealing performance.Thereby make heating proparea plate temperature control in ± 1 ℃ of scope, greatly improved the precision of temperature detection and plate temperature control, for the exploitation and the production of new product are laid a good foundation.
