 Although this article started with a general overview of the iron and steel industry, we will refer only mccullochchainsawhistorey to one process for the rest of this feature, a gray iron foundry using an electric arc furnace. We will see how important brick and refractory are and why everyone should pay attention mccullochchainsawhistorey 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 upon the size of the furnace and can be less then one ton per charge to up to eighty-five tons per charge. It''s great to be able to buy a nice, new, shiny piece of machinery, but that''s just not always possible. New skid steer attachments, depending on their function, can run up to $10,000 or more. Renting is one option to consider, especially when you only need the attachment for a short time.Farm auctions are another good source for attachments. "One definite trend I''ve picked up on over the past year has been the move to sell these attachments separately from the skid steer at auctions," says auction expert Greg Peterson, publisher of the F.A.C.T''s Report (800/381-0423 or machinerypete.com). His service reports machinery prices from auctions around the country. CHICAGO -- I don''t know how many of you took my mccullochchainsawhistorey advice to attend this year''s ASHRAE Show, but it sure was a whopper when it comes to attendance.Unfortunately, while the number of attendees continues to grow, the number of companies displaying their wares has continued to dwindle. This is because many of our industry''s largest players such as Carrier, Trane, York and others have opted not to participate simply because they feel that the results of the exposure they receive don''t justify the high costs involved in displaying.
