Short-circuit annealing machine, mainly for anneal the heaters, which after reducing, the surface is very hard, if without annealing, the bending position is too small, it will be easily got broken or cracked. After annealing, the heaters will become soft.

The machine uses a dry-type transformer, equipped with a pneumatic clamping mechanism to clamp the pipe on the electrodes at both ends, using a low-voltage, high-current to create short-circuit to heat and anneal with metal-shell. 

The annealing machine with shower cooling will automatically spray and cool after annealed.

Auto Anneal machine is with load and unload tubular heaters to anneal automatically.

PS: These anneal machine only anneal part of heater, can not anneal the whole heater.
