ABSTRACT:
In a sintering process a sinter mix containing solid fuel is fed in a layer onto a traveling-grate type of sintering machine. The fuel in the layer is ignited and it burns downwardly under downdraft air to form a resulting solid sinter cake. The sinter cake has an upper portion of sinter that is cool enough to be conveyed on a rubber conveyer belt. The lower portion of the sinter contains a fire zone.
A sinter cake cutter or plow separates along a horizontal plane the cool upper portion of sinter cake and removes it, while the remainder of the sinter containing the fire zone travels along on the strand. The lower portion of the sinter is cooled by updraft air which is recycled into the burning zone.
