Quenching Process
Quenching, the process of cooling hot metal in cold water, or oil, is used to add properties to metals. At high temperature levels, alloying can occur. Alloying is the combination of metallic elements, to give better strength, or opposition to corrosion. Quenching allows to lock in the properties of alloys and does not allow them to precipitate out. If the metals are cooled slowly, the crystals inside the structure will separate. This creates a weaker metal. Quenching creates a solid piece of material beneficial to construction, aerospace and other industries.
Quenching tanks can hold a variety of liquids to cool metals. Each of these will be described throughout the website, with their own properties and characteristics. The liquids include water, brine, oil, forced or still air. Quenching occurs in two types. One is the cooling to obtain the desired crystal structure, and traits of tempering. The other type of quenching involves the cooling of iron-base alloys and other metals.
Quenching is a simple progress to create a desired results. Cooling is a controlled process that brings items about 500° below the starting temperature of 900°C. The hot metal is heated to a specific point and cooled many different ways. An important aspect of quenching is the rate of cooling. This is considered the direct contact between the cooled surface of the tank and the hot formed metal. Another aspect that should be considered is the type of material being quenched. Different materials cool at different rates.
