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： An electric arc roof furnace top contains a central portion and a peripheral portion surrounding the central portion. Each of these portions has an inner surface suitable for facing the furnace inner space. The inner surfaces of the peripheral and central portions form together a step so as to raise the inner surface of the central portion in relation to the inner surface of the peripheral portion with respect to the furnace inner space.

摘要： A cooling system for the distribution and collection of a fluid coolant in a metallurgical vessel used in the processing of molten materials. The cooling system comprises a distribution system including an intake manifold, a plurality of headers attached to the intake manifold, and a plurality of distribution dispensers positioned along each header. A collection system, including a collection manifold, is positioned to collect the fluid coolant. The distribution dispensers are positioned to direct the fluid coolant towards the collection manifold and utilize the majority of the kinetic energy contained within the coolant to direct the coolant towards the collection manifold.

摘要： An electric furnace includes a stationary lower shell having a sloping floor extending downwardly to a tap hole to always maintain a sufficient ferrostatic head three times the tap hole for slag free tapping. The configuration of the refractory for containing a heat, is sufficient to maintain a liquid metal heel of at least 70% of the heat before tapping for maintaining flat bath operation during refining a steel melt. An upper furnace shell is supported on the lower furnace shell and a furnace roof is supported by the upper furnace shell. The entire furnace is mounted on a furnace transfer car that is anchored for stationary operation but moved to a furnace exchange position for servicing any of the components making up the furnace. The furnace roof and/or upper furnace shell may be supported at a furnace operate position while the lower furnace shell is transported to the furnace exchange position.
