10 · Figure 1: The Ironbridge at Coalbrookdale. What makes this bridge so important is the material used and the way it was designed. It was made of cast iron from a blast furnace, and designed in large pieces which could be fitted together and hoisted into position relatively easily. 17 · A typical blast furnace may be up to 32 metres in height and 10 metres in diameter. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. 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 ...

Blast Furnace and its Design – IspatGuru

Blast Furnace and its Design The design of a blast furnace (BF) plays a fundamental role in its reliable operation, metallurgical performance, sustained high productivity and long campaign life. The design of a modern BF is generally based on the concept of a free standing unit with a surrounding building structure, providing access to the ... 20 · The temperature here is about 3500 degrees Celsius, about 2 –3 times hotter than a blast furnace and hot enough to melt iron even under the great pressure that exists at this depth. Because of the dense rocks and high pressure, compressional seismic waves (P-waves) travel at nearly 14 km/s in the mantle just above this boundary.

The next part consisted of creating pellets to be reduced to iron. The last part involved running a series of experiments to reduce the iron oxide to metallic iron.Metallurgy - Metallurgy - Physical metallurgy: Physical metallurgy is the science of making useful products out of metals. Metal parts can be made in a variety of ways, depending on the shape, properties, and cost desired in the finished product. The desired properties may be electrical, mechanical, magnetic, or chemical in nature; all of them can be enhanced by alloying and heat treatment.
