Lower shaft furnace

from Wikipedia, the free encyclopedia

A low-shaft furnace denotes a for the production of ferro-alloys melting furnace used or pig iron with a lower overall height (up to 10 m shaft height) in contrast to the blast furnace . The low-shaft furnace with a round, rectangular or elliptical cross-section allows the smelting of poor ores with low-quality ores with fuels , such as. B. high-temperature lignite coke , which cannot be processed in the blast furnace.

The racing furnaces could be regarded as early low- shaft furnaces , since some of the low-grade iron ores had to be smelted here too.

In 1950, the world's first industrial low-shaft furnace was built in the VEB "Eisenwerke West" in Calbe , and on October 15, 1951 the first pig iron was extracted.
