Red Hot Steel Beam, Drawn Out 90 Feet Long, Steel Works at Pittsburgh, Pa.
RED HOT STEEL BEAM, STEEL WORKS, PITTSBURGH, PA.; Pittsburgh, Pa., is the greatest steel producing city in the whole world. This picture shows a portion of the interior of one of the great steel mills. The iron is sent direct from the mine to the furnace stock pile. These are rooms in these great steel works where the iron ore and scrap iron are melted and transformed into fiery liquid. When this melted iron is drawn off it is about as thick as mild, and is called pig iron. This pig iron is the basis of all steel manufacturing. The liquid iron is then taken in huge ladles by means of electric cranes to converters or mixers. Here it is mixed with carbon of tungsten, or whatever is necessary to give the desired character to the steel. Then heavy ladles are filled with this substance and swung out over ingot moulds. The liquid steel is run into these, and freezes (way above the boiling point) into the desired shape. In the room steel rails are being made. This white, dazzling beam of metal had been rolled out to a length of about ninety feet. From this point it will be carried on rollers to a cutting platform, where it will be sawed into the proper lengths, then sent through a straightening department where the ends will be squared and the holes punched for the fishplates. It is then ready to be shipped.
The rails are loaded by a crane which is itself a huge electro-magnet. This picks up a load of steel rails as easily as a small magnet picks up a cluster of needles.
