Steel Making Process | The Nomadic Engineer

Jan 28, 2016· Steel Making Process. Steel is a metal used in engineering and construction. The base element of steel is iron. The steel making process begins in the blast furnace. The first stage is to mix the iron ore with coke and heat it to form an iron-rich clinker called ‘sinter’. Sintering reduces waste and provides an efficient raw material for

Blast Furnace Charge (Raw Materials for Steel-making

Jan 11, 2013· A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (40-60 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the flue-gas passages and prevent a uniform descent of melting materials in the furnace. 2. IRON ORES: Ore is a metal bearing mineral.

Basic Oxygen Furnace Steelmaking - Steel Technology

The Basic Oxygen Steelmaking process differs from the EAF is that BOF is self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the steel scrap need to be balanced. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is “blown” into the BOF at

How steel is made - a summary of a Blast Furnace

How Steel is Made: a Brief Summary of a Blast Furnace: There are two types of metals, ferrous & non-ferrous. Ferrous comes from, or contains iron, while Non-Ferrous does not contain iron. Some examples of ferrous metals would be mild steel, cast iron, high strength steel…

Decarbonization in steel | McKinsey

Jun 03, 2020· Steel can be produced via two main processes: either using an integrated blast furnace (BF)/basic oxygen furnace (BOF) or an electric arc furnace (EAF). While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.

The Principle of Blast Furnace Operational Technology and

developments in blast furnace iron making. Introduction Kobe Steel started operation as an integrated steel manufacturing company with the blowing-in of the No. 1 blast furnace (BF) at the Kobe Works in 1959.1) We, as latecomers, faced an issue with burden materials, which forced us into high pellet ratio operation requiring central gas flow. A
