An open hearth furnace has a lining of refractory and a low, arched roof that covers the hearth, which is open directly to flames that melt the charge. This process uses about equal amounts of iron and scrap. Steel is produced in an open hearth furnace by the following steps:. 1. A machine dumps limestone and scrap steel (the charge) into the furnace.

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.

6 Steps of the Steel Manufacturing Process. The steel manufacturing process can be divided into six steps: Making the iron, primary steelmaking, secondary steelmaking, casting, primary forming, and secondary forming. #1. Making the Iron. Steel is a metal alloy made of iron and carbon. Thus, the steel manufacturing process starts by making iron.

11. Decline of the Bessemer Process In spite of the basic simplicity, the Bessemer steel suffered from several limitations: • A large part of the heat generated through exothermic reactions is lost in the form of sensible heat of the N2 gas. So, the scrap melting ability of this process is very limited. • The 'N' content in the Bessemer steel is high-of the order of 0.012%.
