Manufacture of Steel during World War II in United States. Bessemer converter seen in tilted position being charged with molten iron from a ladle, under control of crane operator. Bessemer converter operator manipulates lever to cause converter to tilt up and air to blast through the molten iron. This burns excess carbon, silicon and manganese and converts the iron into steel. Molten steel is poured into molds. which are removed after steel solidifies. Hot ingots are moved on rail cars to a place, where they attain a uniform temperature and are ready for rolling. Ingots stored in pit.
Steel production in the United States during World War II. Overhead crane lifts steel ingot and places it into carrier that discharges it onto bed of blooming mill, where it is shuttled back and forth between different segments of water-cooled rollers until it is finally converted into a long steel bar. The steel bar is then rolled through a continuous bar mill, where it is reduced in thickness as it passes successive stations of the mill. At the end, the bar is cut into uniform lengths.
Steel production in the United States during World War II. A steel slab produced from an ingot, is spread on a rolling mill, where it is shuttled back and forth through a succession of water-cooled rollers until it obtains the desired shape. Temperature is monitored and recorded by automatic device. Side view of hot steel plate passing between two rollers. Rolling mill operator seen in control booth. Worker monitors gauges on a panel.. The steel plate continues to reduce in thickness until it becomes a steel sheet.
