A history of more than 170 years of steel making ended in Bochum, Germany in late June when the Nirosta stainless steel plant was closed for good.
The original BOF shop was built in 1957 by the Bochumer Verein to be only the second of it’s kind in Germany.
In 1972, after the closure of the blast furnace site both vessels were transformed into AOD converters and an electric arc furnace was installed in the same building to produce stainless steel.
In 1982 a huge new 135 MVA electric arc melt shop was attached and the old EAF was replaced by a ladle furnace.
I payed the site a final visit before the demolition started.
installed motor capacity makes the ThyssenKrupp hot strip mill in Bochum the most powerful rolling mill in Germany. Though the mill was already planned in the early 1960ies by the Bochumer Verein steel corporation it wasn’t until 1966, after the takeover by the Fried. Krupp company, that the mill was put into operation.
The mill is capable of rolling even high alloyed speciality steel.
After the closure of the adjacent Nirosta steel mill all primary material now comes from the August Thyssen Hütte in Duisburg.

According to a German newspaper the Finnish Outokumpu steel corporation declared yesterday that they will definitely close their stainless steel mill in Bochum, Germany they only just had bought from ThyssenKrupp in 2016.
Main reason are the high energy costs in Germany.
The mills includes an electric arc melt shop built in 1982 (the 145 ton UHP furnace is one of the largest in Germany) and the converter mill built by the Bochumer Verein in 1957.
This BOF shop is the oldest existing in Germany. It was converted into an AOD shop in 1972.
After GM recently announced the closure of it’s Bochum car assembly plant for 2016 this is another heavy blow for Bochum’s economy.
