Annealing furnace: It is a metal heat treatment process in which metal parts are slowly heated to a certain temperature in different annealing furnaces, kept for a period of time, and then cooled at an appropriate speed (usually natural cooling, sometimes controlled cooling) . The purpose is to soften materials or workpieces processed by casting, forging, rolling, welding or cutting, reduce hardness, improve plasticity and toughness, homogenize chemical composition, remove residual stress, or obtain expected physical properties. Today the annealing furnace manufacturer mainly tells you its basic definition and working principle.

1. What is annealing furnace:

The annealing furnace is one of the heat treatment equipment in the machinery industry. Its purpose is to soften the materials or workpieces that have been cast, forged, rolled, welded or cut, reduce the hardness, improve the plasticity and toughness, and make the chemical composition uniform , Remove residual stress, or get the expected physical properties.
2. Principle of annealing furnace:

The annealing furnace is a metal heat treatment process in which metal parts are slowly heated to a certain temperature in different heating furnaces, kept for a period of time, and then cooled at an appropriate rate (usually natural cooling, sometimes controlled rate cooling) .

3. Furnace type of annealing furnace: ①Mesh belt annealing furnace, ②Pit annealing furnace, ③Hood annealing furnace, ④Box annealing furnace, etc.

4. The commonly used annealing processes are: ① Complete annealing. ② Spheroidizing annealing. ③ Isothermal annealing. ④ Recrystallization annealing. ⑤ Graphitization annealing. ⑥ Diffusion annealing. ⑦ Stress relief annealing.
