| Description: | Presents the problems of and solutions for dust and fume control in the heating and pouring of molten steel from, electric furnaces. Discusses environmental questions and answers. "FI on titles and sound of electric furnace electrodes sparking in metal; as titles end, sound reaches a crescendo and cut to white hot pouring of metal in the foundry. Emphasis here is on the dirt and smoke surrounding the workmen. Overhead crane operator looks down on the workmen moving the huge ladle down the casting line. Much smoke. Camera foloows moving overhead crane operator as he tries to see through the smoke. Sunshine brings confusing shafts of light. Pan to smoking furnace. Cut to exterior, blue sky, long shot of foundry, smoke pouring out of the building roof. Zoom in to cars parked beside the foundry. Cut to newspaper clippings of air pollution stories. Titles explain fume control problems. Animated artwork shows elements which must be controlled: fume pickup at the electric furnace, ductwork and outside dust collector. Narrator explains the complications. Four fume pickup methods are shown: canopy, roof, snorkel and direct shell evacuation. Shown in quadrants on screen: roof-type hoods; full roof hood; close-fitting hood; side-draft hood. LS foundry at Simonds Saw and Steel Company in Lockport, NY; show three 13 foor diameter furnaces, with full roof-type hoods, producing tool steel. Animated sequence shows air flow in top and side views. Cut to side view of one furnace; furnace door opens, showing molten interior, and closes. (Narrator describes oxygen lancing) Animation of side-draft hood. Dramatic shot from above, as overhead crane moves huge pot of scrap to the furnace. Cut to white-hot electrodes. Cut to the three electrodes. Cut to workman, CU face. Cut to flames at electrode opening. Cut to sparks as metal is melting. Animation of snorkel method. Dissolve to Atlantic Steel Company in Atlanta, Georgia. LS of snorkel hood on two furnaces. Diss to smoky conditions when air cleaner is turned off, showing what conditions were like before air pollution control equipment was installed. Camera rolls as snorkel is moved into place, and smoke emissions are reduced to a minimum. Cut to exterior shot of the plant against a blue sky, with no smoke emissions. Camera moves to CU of the dust collector, and smoke emission is shown when the system is turned off. Animation of direct shell; evacuation system. Cut to Bethlehem Steel Corporation, Bethlehem PA and pan interior of foundry. An 11 foot and an 8 foot furnace are shown. Cut to CU control damper. Cut to control panels and instruments. Cut to closed damper view of furnace, fumes escaping. Cut to workman lancing the melt. CU flames blasting into the duct, but no smoke escaping. Cut to overhead view of clean roof of the furnace-- no soot. Cut to LS as furnace tilts to pour the metal. Cut to exterior view of dust collector, with by-pass emitting dust which the collector normally removes. Cut to the interior, ductwork and electrodes with no smoke. Cut to operator lancing the melt, and ductworl removing the dust. Animated artwork overhead canopy hood. Cut to Eastern Stainless Steel Co., Baltimore, MD. Camera tilts from furnace to overhead canopy. Tilt down and up to show dense smoke being removed by the overhead collector. Montage summarizes the film to here: interior LS's of of furnaces already shown; smoke pours froma foundry exterior; artwork compares fume particle sizes, large to small, which must be removed. LS as camera moves in on large tube-type collector (clear sky!); dissolve to artwork showing interior. CU collector bag detail. Camera follows duct from foundry to collector: clean sky! LS different view. A series of different collectors, clear sky. Inspector climbs ladder to check floow of collected particles. LS pelletizer, forming the dust into pellets for disposal. Camera moves in to see the pellets forming. End summary montage: electric furnace in clean environment; Wheelaberator engineers at drawing boards; research lab technicians with lab equipment; open furnace and end titles."
