One way of increasing the smelting rate in a blast furnace is to increase the gas permeability of the lower part of the stock. Gas permeability in this zone and the smoothness of the furnace's operation depend on the ability of the intermediate slag to filter through the coke column. A method of studying filterability has been developed and introduced, the method making it possible to ...

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

The History of Iron in Ancient Israel

Eventually, ancient smiths developed a method to produce usable iron, smelting the iron ore in a furnace with charcoal at 1200°C. At this temperature iron was not liquefied, but appeared in a spongy mass, called a "bloom," together with "slag," a mixture of impurities produced as a by-product of smelting.

The pig iron is transferred to the basic oxygen furnace (BOF) along with steel scrap, where oxygen is used to reﬁne the pig iron into steel by re-ducing the carbon content. In direct smelting processes, smelting takes place in a single reactor where ore and coal are both charged into the same melt or bath (hence the name "bath smelting"). The
