Abstract
A pickling facility includes: a pickling tank for storing an acid solution; a conveyance part for continuously conveying a steel plate immersed in the acid solution; a measurement part for measuring at least one parameter which has a correlation with a heat transfer coefficient between the acid solution and a reference surface disposed in the acid solution so as to face the steel plate; and a conveyance speed decision part configured to decide a conveyance speed of the steel plate conveyed by the conveyance part, on the basis of a measurement result of the at least one parameter.
Claims13
A pickling facility, comprising:
- a pickling tank for storing an acid solution;
- a conveyor continuously conveying a steel plate immersed in the acid solution;
- a temperature detector measuring at least one parameter which has a correlation with a heat transfer coefficient between the acid solution and a reference surface disposed in the acid solution so as to face the steel plate;
- a controller configured to decide a conveyance speed of the steel plate conveyed by the conveyor on a basis of a measurement result of the at least one parameter;
- a heat conductor forming at least a first part of the reference surface;
- and
- a heat source disposed in contact with the heat conductor at an opposite side of the heat conductor relative to the reference surface,
- wherein the temperature detector includes at least one temperature sensor configured to measure a temperature inside the heat conductor as one of the at least one parameter.
