摘要： A furnace sidewall having slag retainers and metallurgical furnace having the same metallurgical furnace are disclosed herein. In one example, a furnace sidewall is provided that includes a hot plate and a plurality of slag retainers. The hot plate has an inner surface facing configured to face an interior volume of a metallurgical furnace and a bottom surface configured to face a hearth of the metallurgical furnace. The plurality of slag retainers extend inwardly from the inner surface of the hot plate and are arranged in a macro-pattern of slag retainer groups. The slag retainer groups include at least two or more of the slag retainers arranged in a micro-pattern.

摘要： Embodiments of the present invention comprise a refractory delta made from a refractory material having a cold-face side and a hot-face side. One or more electrode apertures are located in the refractory delta for receiving one or more electrodes. One or more cooling apertures extend from the cold-face side of the refractory material to adjacent the hot-face side of the refractory material. The one or more cooling apertures may further comprise a copper tube. A cooling system delivers a cooling liquid to the one or more cooling apertures, and the cooling liquid draws heat from the adjacent refractory material, including the hot-face side, and evaporates to allow replacement cooling liquid to further draw heat from the adjacent refractory material.

摘要： A furnace cooling panel monitoring system utilizes individual cooling panel data to produce critical monitoring data. An exemplary cooling panel monitoring system utilizes the input from a plurality of temperature sensors configured to accurately measure the temperature change of cooling fluid flowing through each individual panel. The change in temperature from the inlet to the outlet of a cooling panel along with the flow rate of the cooling fluid through the panel can be used to calculate the a heat energy dissipation rate of the cooling panel, or heat flux. The flow rate through individual panels is determined by K-values or resistance to flow constants for a given cooling panel. The heat energy dissipation rate for individual panels can be provided to a user through a computer implemented monitoring program in real time. Alerts may be initiated by the computer implemented monitoring program when a threshold value has been exceeded.
