Furnace
Vagranka - a mine-type furnace. Its cylindrical body is lined with refractory brick. The combustion air is fed through lances located in one or more rows. The loading of the cupola with charge materials is carried out through a blade hole. Molten cast iron flows to the garnets, and then to the collector, from where it is let out through a lawn in a bucket. The slag, which also enters the collector and is located above the cast iron, is released through another crescent, which is located above the cast iron.
