This inves-tigation and careful research convincedthe designers that new methods and prac-tice were necessary. All the information and data obtainedpointed to the necessity for a departurefrom standard machinery, methods andpractice. Before designing the machin-ery, equipment and plant, which for thenew purposes required many innovationsin heating and rolling, it was considered containing thirty-seven questions, eachone important to the establishment ofthe new methods thought necessary, andso prepared as to require little time andeffort in giving the answers. This wassent to a large number of manufacturersproducing pressed and drawn steel spe-cialties, and brought forth immediateand enthusiastic response. The returnsreached forty-seven per cent., which an-swered in whole or in part the entireabstract. With the complete data and reliableinformation then at hand bearing on size,finish, analysis, quality, physical charac-. Fig. 1 is a view of the charging end of No. 1 Heating Furnace together with the Electric OverheadTravelling Crane serving it. The slabs are picked up by this Crane by means of a magnet andplaced on the skids in front of the Massive Pushers. These machines are of unusually heavy designand are electrically controlled and operated. As hot slabs are drawn for rolling, cold ones arepushed into the furnace at the rear or charging end. Fig. 2 shows a partial end and side viewof the No. 1 Heating Furnace with a portion of the Mill Approach Table, Roller Table and of thedelivery end of the Slab Transfer in the foreground. Above the top of the furnace may be seenthe pipes through which is conveyed the air and powdered coal, by means of which the furnace isheated. necessary to consult the trade purchasingand using this class of steel in order toobtain complete data and authentic in-formation.
