Abstract
A method for calibrating a weighing system of a blast furnace top hopper and a corresponding weighing system are disclosed. The method comprises the step of using at least one actuator for exerting a vertical net force with a certain magnitude onto the hopper, so as to simulate a certain weight of charge material in the hopper; and the step of determining the magnitude of the vertical net force. According to the invention, the method further comprises the step of determining the magnitude of a pressure exerting a lifting force onto said hopper and the step of using the determined magnitude of the vertical net force and the determined magnitude of the pressure to establish calibration data for the weighing system.
