BLAST FURNACE (BF) REFRACTORY LINING PATTERN
Blast Furnace An Introduction Blast Furnace is the focus of any integrated steel plant. Blast furnace is used to reduce the iron ore to iron. The charge, which consists of iron ore, coke and limestone etc. in the form of lumps and different ratios, is fed from the top. Air heated in the blast furnace stoves, is applied from the bottom of the
Blast Furnace System Industrial Efficiency Technology
At lower parts of the furnace coke is gasified and the resulting CO reduces ironoxides as it ascends in the furnace. The molten iron trickles down and collects at the bottom. The impurities that are removed by the aid of CaO form a slag that floats on the molten iron.
