The types of quenching furnaces can be divided according to different classification standards, mainly including the following:
Classification by heating method:
Electric heating quenching furnace: Use electric energy to generate heat through electric heating elements, heating evenly, temperature control accurately, suitable for quenching treatment of various metal materials, widely used in automobiles, aerospace, machinery manufacturing and other fields.
Fuel quenching furnace: Generate heat by burning fuel, heating speed is fast but temperature control is relatively difficult, suitable for some quenching processes that do not have strict temperature requirements, especially suitable for rapid heating of large workpieces.
Gas quenching furnace: Generate heat by burning gas, heating efficiency is high and cost is low, suitable for large-scale production, widely used in steel, non-ferrous metals and other industries.
Classification by furnace structure and action mode:
Trolley quenching furnace: Equipped with a movable trolley, it is convenient for loading and unloading and transferring workpieces, suitable for large workpieces, and improves production efficiency.
Pit quenching furnace: The furnace is well-shaped, suitable for slender workpieces such as shafts and long rods, to avoid deformation, and is often used in automotive parts, mechanical parts and other fields.
Box-type quenching furnace: The furnace chamber is box-shaped with a simple structure. It is suitable for workpieces of various shapes and sizes, especially for quenching small workpieces.
Roller-type quenching furnace: The workpiece is placed on the roller, and continuous quenching is achieved through roller transmission. It is suitable for small workpieces produced in batches to improve production efficiency.
Classification by working environment:
Vacuum quenching furnace: The workpiece is heated and quenched in a vacuum environment to avoid oxidation and decarburization. It is suitable for workpieces with high surface quality requirements.
