Synopsis :
For the purpose of stabilizing the permeability of mix bed on the sinter stand, a new permeability control system was developed. In this system the bed permeability was estimated by the permeability index calculated by pressure and the gas volume passing through the wind box just before the ignition furnace, and the permeability index was contorolled by properly setting the cut-off plate. This system was applied to No.4 sintering plant at Mizushima Works. Compared with conventional operation results, variations in B. T. P. and in product quality have been remarkably reduced.
