Rj-90-9 well type furnace can be divided into well type annealing furnace, well type copper annealing furnace, well type vacuum annealing furnace, well type bright annealing furnace, all fiber well type furnace, air circulation well type furnace, well type carburizing furnace, well type nitriding furnace, well type steam bluing furnace, etc.

Well type vacuum bright annealing furnace is mainly used for copper wire, copper wire, copper parts and other copper products.

Well type vacuum bright annealing furnace is mainly composed of heating furnace body, vacuum furnace liner, charging basket, electric control system, vacuum pump, etc.

The steel structure of the furnace shell is welded by various section steels and steel plates to ensure the overall strength of the furnace body and no distortion or deformation of the frame structure. A sealing groove is arranged on the flange panel of the furnace shell to form an effective seal between the furnace shell and the furnace body to prevent heat loss. The furnace lining is made of ultra light 0.6g/cm3 energy-saving fire-resistant and thermal insulation brick, and the interlayer is filled with aluminum silicate fiber cotton; or high temperature resistant ceramic fiber module. The heating element is made of high quality and high resistance alloy cr15ni60.

The furnace is made of 310S stainless steel plate rolled and welded. The standard configuration is one furnace with two tanks (or one furnace with multiple tanks).

The control system of well type vacuum bright annealing furnace adopts PID control, with high temperature control precision, long service life, overload, overheating and over-current protection functions.
