Open hearth furnaces are one of a number of kinds of furnace where excess carbon and other impurities are burnt out of pig iron to produce steel.Since steel is difficult to manufacture due to its high melting point, normal fuels and furnaces were insufficient and the open hearth furnace was developed to overcome this difficulty.

RAMM Global offers ingot molds, slag pots and scrap metals.
SBB's steel glossary is great for finding the definition for any steel term associated to the industry.
According the the IPCC (2007) and Worldsteel (2010), three main routes can be discerned in steelmaking: 1) The primary route. This route, used in almost fifty countries, reduces iron ore to iron in blast furnaces using mostly coke or coal.
Steel Scrap and Scrap Sorting and Preparation Processes. Recycling of steel scrap is receiving increased impetus these days due to the focus of an emerging environmental initiative since the increased consumption of scrap reduces the needs for additional resource extraction and hence reduces the environmental impact.
Steel is one of the most widely used materials, particularly in construction and engineering and in the manufacture of cars. It is estimated that there are over 20 billion tonnes of steel in use, equivalent to well over 2 tonnes for every person on Earth.
Home > Tips and Facts > Foundry Melting Furnaces > Cupola Furnace. The Cupola Furnace. For many years, the cupola was the primary method of melting used in iron foundries. The cupola furnace has several unique characteristics which are responsible for its widespread use as a melting unit for cast iron.
Blast furnace: Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top.
Synopsis: Plasma-furnace technology was first applied in Africa in the mid- to late 1970s, when it was realised that advantages could be obtained in the processing of fines for the production of ferro-alloys.
L Ladle 4. A "bucket" lined with refractory (heat resistant) bricks, used to transport molten steel from process to process in a steel plant.
