What is Face - Hardened Steel Plate?

Face - hardened steel plate is a type of steel plate that has a hardened surface. This is achieved through various processes such as heat treatment or the addition of certain alloys. The hardened face provides enhanced resistance to wear, abrasion, and impact. It is often used in applications where the surface of the steel needs to withstand a great deal of stress or friction.

For example, in the construction of heavy - duty machinery or in the manufacturing of tools. In the mining industry, face - hardened steel plates are used to line the chutes and hoppers where rocks and ores are constantly rubbing against the surface. This helps to prevent premature wear and tear of the equipment, saving costs on repairs and replacements.

How is Face - Hardened Steel Plate Made?

There are different methods to make face - hardened steel plate. One common method is through carburizing. In carburizing, the steel plate is heated in a carbon - rich environment. The carbon atoms diffuse into the surface layer of the steel, increasing its carbon content. Then, the plate is quenched and tempered. Quenching rapidly cools the steel, which makes it hard, and tempering relieves the internal stresses and improves the toughness.

Another method is induction hardening. In this process, an alternating current is passed through an induction coil placed near the surface of the steel plate. The induced current heats the surface layer very quickly. Then, the surface is quenched, creating a hardened layer. These processes require precise control to ensure the right depth and hardness of the hardened face.

Questions and Answers

Question 1: Where can we find the application of face - hardened steel plate in daily life?Answer: We can find the application of face - hardened steel plate in the construction of heavy - duty machinery and manufacturing of tools in daily life. Also, in industries like mining where it is used to line chutes and hoppers.

Question 2: What are the main processes to make face - hardened steel plate?Answer: The main processes to make face - hardened steel plate are carburizing (heating in a carbon - rich environment, followed by quenching and tempering) and induction hardening (using an induction coil to heat the surface quickly followed by quenching).
