Gradient furnace Drawing annealing furnace

Thefurnace chamber of the gradient furnace is divided into 6 temperature controlzones with average length. The temperature of each heating zone can becontrolled separately. The feeding of type a gradient furnace is usuallycarried out from the parallel swing door installed on one side. The maximumtemperature gradient can be adjusted and stabilized at 400 ℃ through theheating length of 1300 mm. If necessary, a second door can be installed on theopposite side as the convection door. When using the attached fiber separator,open the furnace cover and load from the top.

Maximumtemperature 1300 ℃

Heatinglength: 1300 mm

Theheating element is wound on the support tube to heat the furnace by freeradiation

Feedfrom above or through the parallel swing door on the front side

Thefurnace cover is supported by a shock absorber for easy opening

Sixzone temperature control

Sixheating zones are controlled separately (each zone is 160 mm long)

Themaximum temperature gradient of the whole furnace is 400 ℃

Fiberisolation device is used to isolate 6 independent cavities
