We will see how important brick and refractory are and why everyone should pay attention to their brick and refractory designs and installations.History and Background of the Electric Arc FurnaceThe electric arc furnace (EAF) has been around since the early 1900s and is primarily used to produce high quality alloy steels. EAFs have refractory-lined steel shells and vary ill size from only a few feet in diameter to twenty feet or more. The bottom, or hearth, of the furnace is dished to hold the metal charge. The vertical side walls include one or more doors and a tapping spout for removing the melted charge. The roof over the furnace is dome-shaped, and incorporates two or three openings near its center for the admission of electrodes into the furnace. The roof is usually detachable and is lifted off or turned aside for charging. The whole furnace structure is tilted forward and backward for slag skimming or tapping. The furnace capacity will depend chargerpanelsolar upon the size of the furnace and chargerpanelsolar can be less then one ton per charge to up to eighty-five tons per charge.
