Molds

Youngstown Sheet and Tube Company Ingot Molds

In this photograph, workers are pouring molten steel from a Bessemer converter into ingot molds. The Bessemer converter releases oxygen gas through molten iron, which reacts with carbon and other impurities to increase the quality of the steel. The Bessemer converter was invented by Henry Bessemer, who in 1856 took out a patent on the process.

Republic Steel Corporation Electric Furnace Pouring Molten Steel into Ingot Molds

This photograph shows molten steel being poured into ingot molds at the Republic Steel Corporation electric furnace at Plant B, number 2 shop, Central Alloy District in Canton, Ohio.

Republic Steel Corporation was founded in Youngstown in 1889 as the Republic Iron and Steel Company. The company was renamed Republic Steel Corporation in 1927 by Cyrus Eaton, who combined Republic steel with smaller steel companies. It was America’s third largest steel producer. Today, the company manufactures Special Bar Quality (SBQ) steel bars.

Blast Furnace and Molten Pig Iron

This photograph depicts a stream of molten iron at the base of a blast furnace on its way to transport ladles. A pile of slag (solidified impurities) is visible to the left of the iron stream. Blast furnaces burn alternating layers of iron ore and coke (as fuel) by forcing in large amounts of air, forming pig iron. This is the first step of the steelmaking process. This photograph belongs to the Youngstown Sheet and Tube Company Audiovisual Archives, so it likely depicts a Youngstown company plant.
