Single chamber horizontal / vertical annealing vacuum furnace
Characteristics
1.The heating elements are arranged in multi-zones and the temperature uniformity is limited to ±3 ºC
2.Using graphite felt / metal screen as heat insulation layer in heating chamber
3.Using double fans to provide convective flow to improve the heating rate and reduce the heating time.
4.Smart and easy for process programming, stable and reliable mechanical action , automatically, semi-automatically or manually alarming and displaying the faults.
5.Frequency conversion control gas quenching fans, 9 points temperature survey. several grades and isothermal quenching.
6.With whole AI control system and an extramanual operating system.
