Code 3004 applies to employers engaged in steel making operations by means of electric or open-hearth furnaces, or the Bessemer or crucible processes. Includes blooming mills or forging or rolling mills. Applicable to operations which are highly mechanized. Steelmaking includes the various processes of refining or purifying pig iron through melting it in combination with scrap ferrous metals in various types of furnaces with other chemicals and metallic elements to produce various types of structural steel and steel alloys used by manufacturing industries. The electric furnace is used extensively in the recovery of alloy scrap. In addition to the operation of furnaces, this classification includes the casting of molten metal into molds, the operation of blooming mills, and the forging or rolling of steel into various structural shapes such as I-beams, channel irons, angle iron, plate, sheet, and bar steel. This classification does not contemplate any fabricating or assembling operations.
