Tempering Oven

Tempering ovens are used to improve the hardness and elasticity of (steel or other metal) by reheating and then cooling it. Tempering serves as a neutralizing or counterbalancing force.

It is essential to heat the metal gradually to avoid the steel being cracked. The metal is then held at this temperature for a certain period of time. A rough guideline is one hour per inch of thickness. During this time the internal stresses in the metal are relieved. The metal is then cooled by air.

Overview

A Tempering Oven will reduce the metal hardness.

The purpose of a Tempering Oven is to reduce the hardness of any steel or alloy formed product.

Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal.

Tempering is usually performed after hardening or quenching. Quenching is the rapid cooling of the metal conversion to the hardest state to develop martensite, a brittle but extremely strong formation. Tempering is accomplished by controlling the heat of the quenched work-piece to a temperature below its “lower critical temperature”.

Each Industrial Oven project undergoes a comprehensive evaluation of every production requirement. The assessment includes areas such as production goals, part configuration and construction, part mass, temperature profile, and facility location or elevation.
