BOF slag is produced during the transformation process of the pig iron coming from the steel blast furnace. The pig iron reacts with lime, silicates, aluminum oxides, manganese oxides, magnesium oxides, and ferrites depending on the quality of steel produced 2. On the other hand, the Blast Furnace Dust BFD is produced during the transformation
2. A process according to claim 1, further comprising pre-heating shaft furnace blast air using a partial flow of waste gas exiting the gas turbine. 3. A process according to claim 1, further comprising pre-heating said second portion before it enters said gas turbine with a
carefully control gas flow and chemical reactions inside the furnace. The materials are charged into the blast furnace through two stages of conical bells 5 which seal in the gases and distribute the raw materials evenly around the circumference of the furnace throat . Some modern furnaces do not have bells but instead have 2 or
Figure 5 Process flow through No.5 Blast Furnace 5.4.2 Blast Furnace The Blast Furnace is a vertical shaft of circular cross-section and stands approximately 40 m high although the overall facility approaches 100 m. The vessel is internally lined with cooling elements and refractory bricks and blocks.
Once a blast furnace is started it will continuously run for four to ten years with only short stops to perform planned maintenance. The Process . Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches.

Rotary furnaces are usually used to process low-lead-content scrap and residue, while reverberatory furnaces are used to process high-lead-content scrap. The partially purified lead is periodically tapped from these furnaces for further processing in smelting furnaces or pot furnaces. 184.108.40.206 Smelting -
Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
