Hot air circulation system
The hot air circulation system of the industrial ovens consists of an air supply motor, air wheel, and electric heater. The air supply motor drives the air wheel to send out cold air, which is heated by the electric heater and then enters the oven studio of the industrial oven via the air duct. The hot air circulation system in industrial ovens helps to improve the uniformity of the air temperature. In the process of opening and closing the oven door to transport materials, the temperature value will be affected by changes, and the uniformity of the hot air circulation system will help to restore the temperature value in the working state within the maximum speed.

Horizontal and vertical hot air circulation
Industrial ovens control the temperature through the connection of a digital display and a temperature sensor, using a hot air circulation system, which is divided into horizontal and vertical. The air source is driven by the air motor running through the electric heater, which sends the hot air to the air duct and then into the oven studio, and the used air is sucked into the air duct to become the air source and heated again. If the door is opened or closed during use, the air circulation system can be used to quickly restore the operating temperature value.

Common Heat Treatment Methods

There are quite a few heat treatment techniques to choose from. Every one of them brings along certain qualities.

The most common heat treatment methods include:

  • Annealing:

In annealing heat treatment process the metal is heated above the upper critical temperature and then cooled at a slow rate inside the furnace. Annealing is carried out to soften the metal for machining. It makes the metal more suitable for cold working and forming. It also enhances the metal’s machinability, ductility and toughness. Annealing is also useful in relieving stresses in the part caused due to prior cold working processes. The plastic deformations present are removed during recrystallisation when the metal temperature crosses the upper critical temperature. Metals may undergo a plethora of annealing techniques such as recrystallisation annealing, full annealing, partial annealing and final annealing. Furnaces supplied to be applied in aero and astronautical atmospheres must be aligned with the strictest standards and testing systems. Aerospace furnaces that can fully-function within an inner-atmosphere flight have particular parts that cannot be replaced with components of a lower classification.


  • Normalising:

Normalising is a heat treatment process used for relieving internal stresses caused by processes such as welding, casting, or quenching. In this process, the metal is heated to a temperature that is 30-50° C above its upper critical temperature. This temperature is higher than the one used for hardening or annealing. After holding it at this temperature for a designated period of time, it is cooled in air. Normalising creates a uniform grain size and composition throughout the part. Normalised steels are harder and stronger than annealed steel. In fact, in its normalised form, steel is tougher than in any other condition. This is why parts that require impact strength or need to support massive external loads will almost always be normalised.


  • Hardening:

The most common heat treatment process of all, hardening is used to increase the hardness of a metal. In some cases, only the surface may be hardened. A workpiece is hardened by heating it to the specified temperature, then cooled rapidly aka quenched by submerging it into a cooling medium – oil, brine, polymers or most commonly water are used as quenching media. The resulting part will have increased hardness and strength, but the brittleness increases too simultaneously. Case hardening is a type of hardening process in which only the outer layer of the workpiece is hardened. The process used is the same but as a thin outer layer is subjected to the process, the resultant workpiece has a hard outer layer but a softer core. This is common for shafts. A hard outer layer protects it from material wear. When mounting a bearing to a shaft, it may otherwise damage the surface and dislocate some particles that then accelerate the wearing process. A hardened surface provides protection from that and the core still has the necessary properties to handle fatigue stresses.


  • Ageing:

Ageing is a process used to increase strength by producing precipitates of the alloying material within the metal structure. Solution treatment is the heating of an alloy to a suitable temperature, holding it at that temperature long enough to cause one or more constituents to enter into a solid solution and then cooling it rapidly enough to hold these constituents in solution. Subsequent precipitation heat treatments allow controlled release of these constituents either naturally (at room temperature) or artificially (at higher temperatures).

Wrought alloys in the 2XXX (Al-Cu), 6XXX (Al-Mg-Si), 7XXX (Al-Zn-Mg-Cr) and 8XXX (Al-Li) series and cast alloys in the 2XX (Al-Cu), 3XX (Al-Mg-Si-Cu) and 7XX (Al-Zn) series can be solution treated and aged. Final tempers of the T4X, T5X, T6X and T7X types are achievable as a function of alloy by thermal processing only. T3X and T8X tempers are achievable utilising a combination of thermal and thermomechanical processing, such as stretching or compressing simple shapes between solution treating and ageing. Common wrought alloys and tempers are 2014-T4, 2014-T6, 2024-T3, 2024-T4, 2024-T6, 2024-T8, 2219-T3, 2219-T4, 2219-T6, 2219-T8, 2618-T6, 2618-T61, 6061-T4, 6061-T6, 7050-T74, 7075-T6, 7075-T73, 7075-T74, 7075-T76, 7175-T74. Common cast alloys are A201-T7, A206-T7, C355-T6, A356-T6, A357-T6.

Heating below the transformation temperature in order to reduce or eliminate residual stresses in a component. Because no transformation has taken place, the cooling rate is not critical and is generally fairly rapid. Castings and welded fabrications generally contain complex internal stress distributions, which arise from the thermal and material transformations which take place during the foundry and welding operations. If they are not rectified, such stress distributions may be disturbed during further manufacturing operations, leading to distortion or cracking of the components produced. With higher alloy steels and cast irons internal stress can cause distortion or cracking even before any further manufacturing operations are commenced. It is possible, by means of a thermal cycle, generally within the temperature range 550-650°C to reduce or remove the internal stress and render the work piece suitable for further manufacturing operations. Close control of the thermal cycle, ensuring temperature uniformity within the furnace and temperature distribution throughout the work piece is vital and multi-point probe thermocouples are routinely used for this.


  • Tempering:

Tempering is a heat treatment process in which the components are heated and held to a set temperature below the critical point for a certain duration. The components are then cooled to room temperature in still air. Tempering is most often performed after hardening processes where the material is heated above its upper critical temperature followed by rapid cooling. To reduce the brittleness and restore ductility, the metals are reheated, this time to lower temperatures. This helps to strike a balance between hardness and ductility. Tempered metals are useful in applications that need a certain level of flexibility from their components. In theory, tempering can be carried out on a wide range of metals but it is generally associated with carbon steel as few other metals react to this heat treatment method in the same manner as steel.

Carburizing, or carburising, is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder and more wear resistant. In gas carburising, the component is held in a furnace containing an atmosphere of methane or propane with a neutral carrier gas, usually a mixture of N2, CO, CO2, H2 and CH4. At the carburising temperature, methane (or propane) decomposes at the component surface to atomic carbon and hydrogen, with the carbon diffusing into the surface. The temperature is typically 925°C and carburising times range from 2 hours for a 1mm depth case to a maximum of around 36 hours for a 4mm case. The quenching medium is usually oil, but can be water, brine, caustic soda or polymer.
