Légende
This early 1900s photo shows an Inland Steel company blooming-mill machine. The company's business was reducing iron ore to steel. Its only steel mill was located in East Chicago, Indiana, on the Indiana Harbor and Ship Canal and a large landfill protruding out into Lake Michigan. The blooming mill is a big noisy machine for changing the ingots into shapes required. In the center are huge steel rolls revolving toward each other. leading to this is a long train of smaller rollers driven at a rapid rate. the istant an ingot is laid on the far end of the table, it is carried to the jaws of the grooved rolls. When it strikes them, there is a crash like a cannon shot and the ingut is forced through the rolls and comes out thinner and longer than before. Back again it goes through a smaller groove in the same rolls. Thus it passes back and forth, each time through a smaller groove until it is reduced to a long, flat slab.
