Abstract
An enclosure of a steel-making furnace system includes a support structure including a frame that defines an interior, a supply line for supplying a cooling liquid from a reservoir, and a return line fluidly coupled to the supply line and the reservoir. A plurality of panels includes sinuously winding piping having an inlet and an outlet. The inlet is fluidly coupled to the supply line and the outlet is fluidly coupled to the return line. The frame includes a plurality of support members spaced from one another, where each of the plurality of support members defines a slot. Each of the plurality of panels is removably and slidably received with the slot for coupling to the frame.
