Heat Treatment is the procedure of heating and cooling metals to change their physical and mechanical properties without changing their shape. Basically, it is a mechanism for strengthening materials but could also be used to transform some mechanical properties such as improving formability, machining, etc. This module helps you to understand the different Heat Treatment process that is required to change metals' physical and chemical properties.

Steelmaking is the process of producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, Sulphur, and excess carbon are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen, and entrained impurities (termed “Inclusions”) in the steel is also important to ensure the quality of the products cast from the liquid steel. The module takes us through the best steel-making practices in an industry.

Combustion is the conversion of a substance called a fuel into chemical compounds known as products of combustion by combination with an oxidizer. Fuel is the backbone of any industry and the knowledge of the fuel properties helps in selecting the right fuel for the right purpose and efficient use of the fuel. The module explains the different types of fuels used in industry and explains the combination of those different fuels for combustion.

Desulphurization of hot metal is an important step in the steel production process. Sulphur in steel negatively influences both mechanical and corrosion properties of the steel and causes hot shortness. A major source of sulphur in the hot metal is the coal used in the blast furnace. As the usage of lower grade coal is being more common, more sulphur is introduced into the hot metal. Thus, there is an increased need for efficient Desulphurization of hot metal. Thus the module explains the importance of Desulphurization in achieving the best quality of steel.

Steel Making can be divided into three parts. Primary Steel Making, Secondary Steelmaking, and Casting. The secondary Steelmaking Process is the process where final refining and finishing treatment is done after primary steelmaking to achieve the required quality of Steel. With an increase of stringent quality requirements of steel, the role of secondary steelmaking in steelmaking is getting more important. 

Refractory is the backbone of the Steel Industry. A complete understanding of ‘Refractory application and maintenance’ will permit us to handle operational excellence as per current industrial requirements. The E-learning course on “Refractories and heating” will help acquire knowledge in the following areas like Basics of refractory material, Types of refractory, Monolithic application, Properties, and testing of refractories. Application of refractory in the steel industry. This e-learning module is equally worthful for people working in the Steel Industry & students of the Ceramic & Metallurgical disciplines.
