Factors to be considered in selecting vacuum annealing furnace
Vacuum annealing furnace is an important equipment to realize vacuum heat treatment. With the application of vacuum annealing furnace in our production and life more and more widely, the choice of vacuum annealing furnace has become a headache for consumers, so what are the factors to be considered in the selection of vacuum annealing furnace? Now I'll introduce you to editor.
1. The relationship between the equilibrium decomposition pressure of metal oxide and carbon monoxide shall be realized according to the chemical composition of the parts to be heat treated and the heating temperature, and certain leeway shall be considered.
2. The cooling of vacuum annealing furnace includes oil cooling and air cooling, mainly air cooling, because air cooling has no pollution and adverse effect on heat treatment parts. Therefore, under the condition of satisfying the cooling rate, air-cooled quenching is generally selected.
3. There are some differences in the form and material of the heating elements of the vacuum annealing furnace, generally plate type and rod type are the most. It can be selected according to its own needs.
4. The universality of the process shall be considered when purchasing the furnace for function, that is, the range of quenching and tempering temperature shall be wide.
5. The control system is the core part of the vacuum annealing furnace, which ensures its reliability and importance. It has the functions of monitoring, fault display and recording, which need to be equipped with the remote monitoring function.
6. The reliability of other sealability and vacuum system configuration is also an important link, which can be made as reliable as possible on the basis of comparison.
These are the factors that need to be considered in the purchase of vacuum annealing furnace, hoping to help you.
