Abstract
PURPOSE: To effect highly accuracy control of coating layer thickness in continuous production of coated steel plate by a method wherein layer thickness detection signal at the outlet of coating machine is compared with preset thickness signal, and the results are used to control steel plate heater provided at the inlet of the coating machine.
CONSTITUTION: Coating layer thickness detector 14 gives actually coated thickness signal, which is campared in the comparator 15 with preset signal for coat layer thickness. The signal difference is converted in the controller 17 to current to control strip heater temperature in the strip heater 12. This results in accurate control of coating material viscosity at the location where coating material is applied to the strip, so that highly accuracy uniform coating thickness is provided.
