Choose the Right Heat Treatment Furnace
“Picking the most suitable furnace for an industrial application requires knowledge of the factors & processes needed for the manufacturing & production lines.“
An industrial furnace goes up to 1000°C – 1200°C or higher. Allowing manufacturers to use for its heating & cooling capability on various materials (e.g. metals) to change their quality and properties to meet with industrial or market standards.
Why do manufacturers need such a high temperature?
- Alter or fabricate the physical or chemical properties of a material.
- Change the grain structure or mechanical properties of material so that it becomes useful, serviceable and for human safety during and after the production line operations.
- Making materials harder, stronger and more resistant to impact or softer and ductile.
- Increase resistance to wear, tear, heat, corrosion, etc.
- Improve electrical and magnetic properties (for metals)
Using just one furnace cannot produce all of this characteristic or result as mentioned above. Sometimes manufacturers have to use multiple types of heat treatment methods and furnaces to achieve the desired results.
FACTORS TO CONSIDER
To ensure smooth operations with the heat treatment process, manufacturers need to know the:
- The purpose for which type of material needs to be heated
- Source of heat and the Nature of heat transfer to the material
- Heating by batch or continuously and the method of handling materials
- Type of heat recovery
- Other types of furnace classifications
HEAT TREATMENT TYPE TO CONSIDER
- Helps to increase the temperature of the material slowly for the control of the thermal stress.
- Prevent or reduce chances of the material to crack, contract, or expand (from thermal stress).
- Removes thermal stress by heating up then slowly cooling down the metal.
- Capable of making the material softer, refine, or change its ductility or structure.
- Heats up the material with a high temperature and then follow up with a quick cooling process (by quenching in water, oil, or molten salt) to increase material’s resistance to penetration (hardness).
- Carbon found in the material and the rate of cooling from a high temperature can create different grades of hardness, softness, toughness, and other properties.
- After this heat treatment, tempering or annealing can be used to slightly modify the material’s quality and characteristics.
- Involves slow and moderate heating to increase the hardness and toughness of the materials e.g. metals that have undergone previous heat treatment.
- Improve toughness, strength, plasticity, and impact strength of the materials (opposite of annealing)
The above is only a quarter of heat treatment application available in the industrial market and methods.
