The principle of selecting metallurgical heat treatment equipment

First, the type of metallurgical heat treatment equipment Heat treatment equipment mainly includes heating equipment, cooling equipment and furnace instruments. Among them, heating equipment is the main equipment in the heat treatment process. For preheating, resistance furnaces and gas furnaces (box type, well type, and trolley type) are usually used. The final heat treatment usually uses bath furnaces, induction heating equipment, well-type gas carburizing roads, electric resistance furnaces, and gas stoves. High-quality final heat treatment is used. Usually controllable angry furnaces, controlled angry multi-purpose furnaces, vacuum heat treatment furnaces are used. The main technical performance indicators of the heat treatment furnace are rated temperature, rated power, working voltage, furnace size, productivity, maximum furnace capacity, and air-warming time.

Heat treatment equipment is a means to perform heat treatment process, and is an important tool in heat treatment production process. After the heat treatment process of the part is established, the heat treatment equipment is the key to determine the heat treatment quality of the workpiece. Reasonable selection of heat treatment equipment according to the requirements of the process can reduce the processing cost and realize Energy-saving and emission reduction targets.

Second, the principle of choice Selection of heat treatment equipment principles - the combination of advanced and practical 1 to meet the requirements of heat treatment process; 2 to ensure the quality of the workpiece heat treatment; 3 is conducive to improving production efficiency and reduce production costs; 4 to ensure the service life and maintenance convenience; Energy-saving, emission reduction and safe production.

III. Classification of heat treatment equipment Heat treatment equipment is divided into major equipment and auxiliary equipment. Heat treatment The main equipment includes: heat treatment furnaces, heating devices (such as induction heating devices, etc.), surface modification devices (vapor deposition and ion implantation, etc.), quench cooling devices, and cold treatment Device, process parameter detection and control device. Heat treatment equipment auxiliary equipment such as cooling, cleaning, atmosphere preparation, quenching media circulation, fire and dust removal.

Fourth, the working principle of heat treatment equipment Induction heat treatment is the alternating current through the inductor, so that it produces alternating magnetic field around the inductor, when the workpiece is placed in the sensor with alternating magnetic field, the alternating magnetic field and the workpiece to produce magnetic induction Therefore, induced electromotive force and induced current are generated to heat the workpiece.
