Abstract
The utility model discloses a steel wire balling annealing furnace. The steel wire balling annealing furnace comprises a furnace body, an inner bucket and a furnace cover. The furnace body is provided with a gas heating spot, a fan is arranged inside the inner bucket, a motor driving the fan is arranged below the furnace body, a shaft barrel on the bottom of the inner bucket extends out to the outside of furnace body, and a rotating shaft connecting the motor and the fan penetrates through the shaft barrel. In the process of long-term production, heat insulation cotton and fire-resistant tiles are aged, waste gas in a combustor is exhausted outside the furnace body from an outer wall of the shaft barrel and does not enter into the inner bucket, and therefore annealing quality of steel wires can be improved.
