what temperature does pig iron melt? | Yahoo Answers

Sep 10, 2009 · Liquid iron collects at the bottom of the blast furnace, underneath a layer of slag. The blacksmith periodically lets the liquid iron flow out and cool. At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron.

Basic oxygen steelmaking - Wikipedia

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
