The open-hearth furnace lived a century and a

half The open-hearth furnace is a melting furnace in which it is possible to

melt cast iron and scrap of ferrous metals into steel of the desired chemical
composition and quality. It is named after its creator, French engineer and
metallurgist Pierre Emile Martin. The first sample was created in 1864. In
Russia, such a furnace first appeared three years later - in 1866 - 1867,
a 2.5-ton unit was built by industrialist Sergei Maltzov. On March 16,
1870, this furnace was installed at his Sormovsk plant (Nizhny Novgorod)
by industrialist Dmitry Benardaki. Later, other industrialists took over the
innovation as they opened the open-hearth furnaces at the Yuzovsky
plant in Donetsk, Putilovsky and Obukhov factories in St. Petersburg
and other places. In the 21st century, the open-hearth production
method was supplanted by other, more efficient and more
environmentally friendly ones. The last open-
hearth furnace in Russia was no longer used
in 2018. It was at the Vyksa Metallurgical
Plant in the Nizhny Novgorod Region. The
furnace seriously affected the environment -
according to the Ministry of Industry and Trade, with
its closure, harmful emissions into the air from the plant
Pierre Emile Martin
should be reduced by 90%.
