Utilization Optimization of Ferroalloys during Steelmaking

Utilization Optimization of Ferroalloys during Steelmaking Ferroalloys are alloys of iron with a high percentage of one or more of other elements such as silicon (Si) and manganese (Mn) etc. They are brittle and unsuitable for direct use in fabricating of products of use. Ferroalloys are important raw materials for the steelmaking process. They are …

Main Features of a Modern High Capacity Blast Furnace

Main Features of a Modern High Capacity Blast Furnace The performance of an integrated steel plant is highly dependent on the performance of its ironmaking units. In integrated steel plants, production of hot metal (HM) in a blast furnace (BF) is a preferred route globally for ironmaking. The specific cost of steel production is highly …

Tinplate and Process of Tinning

Tinplate and Process of Tinning Tinning or tinplating is the process of thinly coating sheet or strip of steel with tin (Sn), and the resulting product is known as tinplate. Tinplate is light gauge, cold-reduced low-carbon steel sheet or strip, coated on both faces with commercially pure tin. It combines the strength and formability of steel and the corrosion resistance, …

Galvanizing of Steel

Galvanizing of Steel Galvanizing of steel means application of zinc on the steel for corrosion protection. The major types of commercially available methods for applying zinc coatings are hot dip galvanizing, continuous galvanizing process, electro-galvanizing, zinc plating, mechanical plating, zinc spraying, and zinc painting. Each of these zinc coating methods has unique characteristics. These characteristics …

Carbon Capture and Storage Technologies

Carbon Capture and Storage Technologies Carbon capture and storage also called sequestration (CCS) involves the capture, transport, injection and containment of CO2 (carbon di-oxide) in geological structures such as depleted oil and gas reservoirs, onshore and offshore saline aquifers located deep in the earth’s crust, salt caverns or unmineable coal beds. It is both an approach to enhance …

Theoretical Aspects of Direct Reduction Process

Theoretical Aspects of Direct Reduction Process In the direct reduction process of iron ore, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion. Direct reduction can be defined as reduction in the solid state at oxygen (O2) potentials which allow reduction of iron …
