Abstract
The present discloses a thermal energy recovery auxiliary system for temperature detection of molten steel in a steelmaking process, comprising an electric arc furnace, a water supply device, a power generation system, a piston type oxygen compression device, and one or more non-contact temperature measurement devices. A flue communicates with a side wall of the electric arc furnace. The water supply device includes a water supply tank, a water supply pipeline of an electrolytic cell, and a thermal energy recovery component. The power generation system includes a Seebeck-effect thermoelectric power generation component and an electrolytic cell. The piston type oxygen compression device forms a steam containment chamber and an oxygen containment chamber through a piston isolation. One end of each of the one or more non-contact temperature measurement devices communicates with the oxygen containment chamber and the other end of each of the one or more non-contact temperature measurement devices communicates with an interior of the electric arc furnace.
