Abstract
This application addresses a wireless system for the determination of the height of liquid or molten metal levels containing metal, shaft, matte or slag in smelting furnace. Specifically, it addresses a wireless system that allows, without the presence of cables, the sending and receiving of a signal outside of the smelting furnace, in order to determine, on-line, the height of the phases, including the height of the slag-matte interface and the total level of the bath.
Claims8
Wireless system to determine the height of levels of liquid or molten metals within metal, shaft, matte or slag pyrometallurgical smelting reactors, CHARACTERIZED in that it is comprised of a programmable logic controller (PLC) equipped with a wireless transmitter-receiver device that has analog inputs and discrete outputs connected to a circuit of solid-state and electromechanical relays. Said circuit is connected to electrodes (1) placed in a melting furnace (2), which are submerged in a specific phase of the metallurgical bath within the furnace. Said programmable logic controller is connected via the transmitter-receiver device to a control interface.
