Document Type and Number:
Japanese Patent JP2021081113
Kind Code:
A
Abstract:
To make the running cost of a bag filter lower than the conventional one.SOLUTION: A steel making system subjecting an exhaust gas generated upon melting a metal raw material by a melting furnace to purification treatment comprises an exhaust gas purification device, where, regarding slag generated together with the metal raw material in the melting furnace (electric furnace 4), under installing a dust removal machine 7 installed at the inside between a bag filter 9 and an electric furnace 4, powder dust with a relatively large diameter in the exhaust gas is filtered, further, the exhaust gas is cooled by a heat conduction tube passing through the slab, and that is connected to the bag filter 9.SELECTED DRAWING: Figure 1
