The invention relates to the production process technology of double-furnace blister
copper continuous converting. According to the technical scheme, a double-furnace blister
copper continuous converting process is uniquely characterized in that two furnace kilns which are arranged front and back continuously complete the process of forming blister
copper through copper matte by means of converting, and the two furnace kilns are named as a
slag formation furnace and a copper formation furnace. The process flow includes the steps that the copper matte produced by a
smelting furnace continuously flows into the
slag formation furnace, and in the
slag formation furnace, the copper matte chemically reacts with
solvent added into the slag formation furnace and
oxygen-enriched air blown into the slag formation furnace, so that converting slag, white copper matte and high-temperature gas are generated; the converting slag is continuously discharged out of a slag
discharge opening in an overflow mode, and placed in a
slow cooling slag
ladle through a chute, the white copper matte sinks to the furnace bottom, is discharged through siphoning and continuously flows into the copper formation furnace through the chute, and the high-temperature gas enters a
waste heat boiler; in the copper formation furnace, the white copper matte chemically reacts with the
solvent and the
oxygen-enriched air which is blown in, so that the blister copper, a trace of converting slag and the high-temperature
smoke are generated; the blister copper is continuously or intermittently discharged through siphoning by means of the chute, the converting slag is regularly discharged out of the slag
discharge opening in the overflow mode, and the high-temperature gas enters the
waste heat boiler.
