Bright strip steel coil annealing furnace - divided by door into heating and cooling zones with circulating convection systems

摘要

A bright annealing furnace for cold-rolled strip in coils is divided by a movable partition into a heating zone and a cooling zone, both with forced circulation. As one coil on its trolley is being cooled in the cooling zone, another coil on its trolley is heated up to the annealing temp. in the heating zone. Method simplifies the handling of the coils and prevents the heat losses inherent in the batch types annealing box method. The continuous system has a high throughput rate.
