Pig iron - blast furnace route | International Iron ...

Pig Iron Production - Blast Furnace Route. More than 1.1 billion tonnes of blast furnace iron was produced globally in 2016. Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces. Modern blast furnaces produce more than 10,000 tonnes per day.

Mechanical Types of Furnaces used in Metal Industry

Cast- iron spirally arranged shelves assist in raising and showering the pulp through the flames. To both White and White- Howell furnaces an auxiliary fire is often added for roasting the dust which escapes from the main furnace. The dust, when it has been completely roast ed, is shovelled out and mixed with the main bulk of the ore by hand.

Machining Cast iron In a Lathe or Mill - STEAMSHED

Cast iron machining in a lathe or mill needs a very slow speed to cut it properly – too high and there will be sparks everywhere and your tools will need re-sharpening very quickly. As a general rule of thumb, to get a smoother finish on cast iron, you tend to need a finer tip on your cutting tool with very slow transition along the work.

By 1880 the annual output of the Superior mines had risen to almost 2 million gross tons. Cleveland's strategic position as both a final destination and a transshipment point for iron ore underscored a vexing problem—how to unload it efficiently—that was solved by two Cleveland inventors. Until 1867 ore was unloaded entirely by hand labor.

Cast iron contains 1.8 to 4.5 percent carbon and additives like silicone, magnesium, chromium, molybdenum, and copper to improve rigidity and ductility. The resulting cast iron grades range from Brinell hardness numbers (BHN) of 150 to 300. That means that even though they're all cast iron, they respond differently to turning.
