Thermal ovens are specially designed industrial furnaces that perform heat treatment (aging) to improve the mechanical properties of aluminum profiles. These ovens perform controlled heating at specific temperature and duration to increase hardness, strength and durability of aluminum after extrusion. Acrotech thermal ovens are designed as static chamber type and are widely used in the aluminum industry, automotive and construction sectors with their homogeneous heat distribution and high temperature accuracy.
Process air heating is performed with proportional natural gas or diesel burners. The internal recirculation of hot air from the radiant tubes produced by the burners is achieved by using medium-prevalence centrifugal fans that rapidly blow air towards the duct system. Air flows from one furnace wall to the other.
This ensures very short air circulation for shorter aging cycles and the best temperature accuracy. The openings in the ducts are adjustable. This is important to ensure uniform airflow throughout the entire load area. At the end of installation, the dampers are adjusted once with the help of flow measurement devices. This solution achieves a perfect homogeneous airflow flowing crosswise to the aluminum profiles.
We can guarantee ±5°C profile temperature accuracy after the heating ramp time with our aging oven. The same temperature margin is ensured as in thermocouples. The heating block is insulated with 160mm thick, 850°C resistant 150 kg/m³ rock wool between two walls.
This high insulation capacity saves energy and creates a safe working environment by keeping the oven outer surface temperature low.
Radiant tubes are manufactured from AISI 310s stainless steel. This material provides long service life and corrosion resistance at high temperatures. The radiant tube diameter decreases as it moves away from the burner, achieving higher efficiency.
This design optimizes homogeneous heat distribution and minimizes fuel consumption.
Chain or roller transport are the systems we use to move the load in and out of the oven. Top loading is also possible. In this case, the oven roof will be directed by an overhead crane.
Flexible loading options adapt to different profile sizes and production capacities.
One of the special features of this oven type is the modularity in which it is created. Once an oven module is installed, other modules can easily be added to accommodate production changes such as quantity or size changes while maintaining the same excellence.
This feature allows you to increase oven capacity in parallel with your business growth and optimizes the initial investment cost.
