Failure mode effect analysis is executed by a multidisciplinary team of experts in blast furnace operation with the help of process flow chart the
blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.
- blast furnace boilers/stoves receiving 90% of total annual gas from blast furnace gas. (40 CFR 63.7491) A process heater is an enclosed device with a controlled flame that has a primary purpose of indirectly transferring heat instead of generating steam. Indirect process heaters include devices in which the combustion gases

Blast furnace slag is a nonmetallic coproduct produced in the process in the production of iron from iron ore or iron scrap. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by
It is of critical importance to keep a steady operation in the blast furnace to facilitate the production of high quality hot metal. In order to monitor the state of blast furnace, this article proposes a fault detection and identification method based on the multidimensional Gated Recurrent Unit (GRU) network, which is a kind of recurrent neural network and is highly effective in handling ...
