Heat treatment is being carried out in different industries. Heat treatments of metal are applied after the metal has been exposed to all production processes such as rolling, casting, welding and forming. The execution of those processes may cause damage to the structure and mechanical properties of the metal. Therefore, it is important to subject your metal to proper heat treatment. Delta Heat Services is expert in the field of heat treatment and has various annealing furnaces available.
Heat treatment
Heat treatment is the process of heating and cooling metal in order to change its forms and structure. It is mainly used to improve strength, hardness, ductility and corrosion resistance. There are different forms of heat treatment that can be used for the editing of metal. Common methods include annealing, normalizing and pre and post weld treatment.
Electrical heat treatment
Electrical heat treatment is carried out with the assistance of electric heating elements. The heat current causes resistance in the elements, becoming hot. This provides heat to the workpiece. This method is used during the preheating of welds as well as the local annealing of welds. Delta Heat Services makes use of heat treatment units that have maximum mobility in the field. For example, the 50kVA units are perfect for on-site and shop working. They can control six individual thermocouples in order to execute preheat or post weld heat treatment.
Induction heating
Induction heating is perfect for the preheating activities on heavy construction works. Due to an induced current, the workpiece inserted into the induction coil will heat up to high temperatures. This method is mainly used in order to heat up heavy materials. The induction cables can be placed in round coils for pipes or in custom made shapes for construction work. If a moving item needs to be heated, Delta Heat Services offers the rolling inductor. This simple, cost-effective heating solution delivers a fast and consistent heat. It is controlled by a thermocouple that is specially designed for controlling and measuring the temperature when the workpiece is moving.
Annealing furnaces
Delta Heat Services performs on-site heat treatments. Our stationary annealing furnaces can be used for a wide variety of heat treatment applications, regardless of size or weight. Therefore, we could execute a heat treatment at any location. Our annealing furnaces are oil-fired or electrically heated and they vary in sizes which go up to a maximum of 18,5 meters. View this page for an overview of the dimensions of all our annealing furnaces.
Reasons to execute treatment
When metal gets exposed to extreme heat, it causes it to expand. Besides, it can impact the structure, electrical resistance and magnetism of the metal. It also makes the metal softer, weaker and it increases its ability to stretch. By executing heat treatment in a proper manner, all of those threats are being limited.
