Sealed box type non-oxidation spheroidizing annealing furnace

Brief

This sealed box type non-oxidation spheroidizing annealing furnaceproduction line is newly designed and manufactured by our company, mainly used for non-oxidation spheroidizing annealing.

Application field

1.Bearing roller, bearing ring and hot forgings(Heat treatment materials ,such as Cr15,GCr15SiMn,bar and wire rod materials);

2.Copper bar, copper pipe and copper wire;

3.Aluminium alloy and magnesium alloy.

Structure

This production line mainly consist of heating furnace, nitrogen making machine and electric control system.

The heating furnace body including furnace shell, furnace lining,furnace inside walking device, furnace inside hot air circulation device, sealed radiant heater, furnace door hoisting appliance, furnace door cylinder pressure and silicone rubber sealing device, driving device of furnace inside bearing vehicle.,etc.

Advantages

1.The whole heat treatment process is operated by PLC automatically, easy to operate, saving labor costs;

2.Using the protective atmosphere, ensure that the heat treatment material is  bright and no oxidation.
