Pit type heat treatment furnace is a commonly used equipment for metal material heat treatment, named after its appearance resembling a wellhead. It plays an important role in industrial production, capable of strengthening, annealing, normalizing, quenching, and other heat treatment processes on metal materials to improve their mechanical properties, wear resistance, and other characteristics, thus meeting the needs of various engineering applications.
Structure and working principle
The basic structure of a Pit type heat treatment furnace includes the furnace body, heating elements, control system, and cooling system.
The furnace body is usually made of high-temperature resistant materials to ensure the stability and sealing of the high-temperature environment inside the furnace. Its appearance resembles a wellhead, and the top is usually equipped with an opening for easy insertion and removal of workpieces.
The heating elements of a pit type heat treatment furnace mainly include resistance wires, induction coils, etc., which are responsible for converting electrical energy into heat energy and transmitting it to the workpiece in the furnace.
The control system usually includes temperature controllers, power controllers, etc., used to monitor and adjust parameters such as temperature and heating power in the furnace to ensure that the heat treatment process is carried out according to the set process requirements.
After the heat treatment process is completed, the cooling system will quickly reduce the temperature of the workpiece to fix its obtained structure and properties.
