Sintering plant | UNESCO Visitor Centre

Year of construction: 1928, added to in 1938
In operation: 58 years until the works were shut down

One of the largest sinter plants in Europe was built in Völklingen in 1928. Sintering is a high-temperature process that is used to fuse together the ore dust that is produced when iron ore is crushed for use in a blast furnace. This was done by heating it up to melting temperature. The material was then broken into pieces about the size of a fist, cooled, and reused in the blast furnace. This reduced the consumption of raw materials and improved the quality of the pig iron.

The plant was built by LURGI AG of Frankfurt, and operated in the American Dwight Lloyd process. In the 1930s, the sinter plant at Völklingen was one of the most productive in the world with a monthly output of 55,000 tons of sinter.
