Technical Field
The invention relates to the technical field of electromagnetic valves, in particular to an electromagnetic injection valve used on a sectional cooling system.
Background
In the cold rolling process of metal steel, aluminum, copper and other strip, the hot convexity of the rolling mill roller directly influences the plate shape of the rolled strip, and in order to obtain high-quality cooled strip and improve the yield of the rolling mill, the roller is finely sectionally cooled according to the size of the hot convexity according to the change of the plate shape of the online strip. The finer the segmentation, the more precise the control of the roll thermal crown.
At present, a pneumatic electromagnetic valve or a manual valve is mostly adopted to control a piston type cylinder to open a cooling liquid valve during the cooling of a roller in the cold rolling process of a plate strip. The disadvantages of this method of controlling the coolant are:
1. a large installation space is required. The subsection is more than 60-100 mm, so the change of the hot convexity of the roller cannot be accurately and sectionally controlled.
2. The control signal must first control a pneumatic solenoid valve or a manual valve. The pneumatic valve controls the piston type cylinder to open the cooling liquid valve, and a longer delay process is formed from signal acquisition to implementation control, so that the plate type quality of the online plate strip cannot be corrected in time.
3. The method only can open or close the cooling liquid valve, and cannot precisely control the flow of the cooling liquid in a pulse width adjusting mode. The requirement for rapid control of the roll thermal crown cannot be met.
4. The multi-core capillary tube consists of a plurality of multi-core capillary tubes, and has the advantages of large workload, large occupied space and many hidden dangers.
