Reheating furnaces are crucial in the steel industry for bringing steel billets or slabs to the desired temperature before subsequent processing, such as rolling or forging. While reheating furnaces play a vital role in the steel production process, there are some disadvantages associated with their use. Here are several drawbacks: Reheating furnaces often consume a […]
Direct hot rolling is a process in steel production where the steel is rolled into its final shape directly from the casting stage, without the need for additional reheating. Several parameters influence the efficiency, quality, and overall performance of a direct hot rolling mill. Here are the key parameters affecting this process: Efficient control and

The concept of a “direct hot rolling mill” refers to a type of rolling mill that eliminates the need for a separate reheating furnace before the rolling process. Traditional hot rolling mills involve a reheating furnace where the metal (usually steel) is heated to a high temperature before being fed into the rolling mill. The

Induction melting furnaces (IMFs) are widely used in the steelmaking industry to produce high-quality steel. Here is a summary of the steelmaking process in an induction melting furnace: Induction melting furnaces utilize electromagnetic induction to generate heat within the metal. A high-frequency alternating current (AC) is passed through a coil, creating a magnetic field that
