PRODUCTION OF IRON AND STEEL POWDERS

account for more than 90% of the world production of iron and steel powders, viz. the Höganäs sponge-iron process and the water-atomizing process. The former process is based on reduction of iron ore, yielding a highly porous sponge-iron which subsequently is comminuted to powder. The latter process is based on atomization of a stream of liquid iron (or steel) by means of a jet of ...

Steel Production - American Iron and Steel Institute

How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production

ORB: Iron and Steel Production in the Middle Ages

Carbon is the major variable that distinguishes between wrought iron, steel, and cast iron. Too little, and one gets wrought iron; too much and the iron begins to flow as cast iron. Just the right amount of carbon (around 1% or a bit more) and you've got steel. So why didn't everyone make steel? Because the smelting furnace doesn't let the operator control the carbon content with any degree of ...
