heat treatment furnaces classification

The main equipment for heat treatment is the necessary equipment for the completion of the heat treatment process. Such equipment plays a decisive role in the heat treatment effect and product quality, and the heating equipment is the most important. The heating equipment includes various resistance furnaces, bath furnaces, fuel furnaces, controlled atmosphere furnaces, vacuum furnaces, etc., which are important equipment in the heat treatment workshop. In order to facilitate the selection and comparison of analysis, it is often classified according to the following methods.

1. Heat source classification : Resistance furnace, fuel furnace.

2. Working temperature classification :Low temperature furnace (<650 °C), medium temperature furnace (650-1000 °C), high temperature furnace (＞1000 °C).

3. Furnace media classification: Air furnace, bath furnace, controlled atmosphere furnace, flow particle furnace, vacuum furnace, ion carburizing furnace.

4. Furnace type classification :Box furnace, pit furnace, trolley furnace, pusher furnace, rotary bottom furnace, vibrating bottom furnace, conveyor belt furnace.

5. Process classification: Normal furnace, annealing furnace, quenching furnace, tempering furnace, carburizing furnace, nitriding furnace, carbonitriding furnace.

6. Operating procedures classification: Cycle operation furnace, semi-continuous operation furnace, continuous operation furnace.
