CONTACTLESS POSITION MEASUREMENT OF A MOVABLE LANCE IN CONVERTER STEEL PRODUCTION

摘要

A system including a movable lance (1), which measures or influences physical or chemical quantities of a melt (2) in a converter (3), and a device for contactless position measurement of the movable lance (1). Also, a converter system including such a system and a method for the contactless position measurement of the movable lance (1). For position measurement of a movable lance (1) in converter steel production, the system has a stationary transmitter (4) for emitting electromagnetic waves (7), a stationary receiver (5) for receiving the emitted electromagnetic waves (7), a reflector (6), which is connected to the movable lance (1) and on which the electromagnetic waves (7) can be reflected, and a calculator (8) for calculating the absolute position of the lance from the propagation time of the electromagnetic waves (7) emitted by the transmitter (4) in the direction of the reflector (6), reflected by the reflector (6) in the direction (2) of the receiver means (5), and received by the receiver (5).
