Description
Technical field
The utility model relates to field of metallurgical equipment, relates to a kind of metallurgical slag continuous blow-down system more specifically.
Background technology
Metallurgical industry is the pillar of the national economic development, and the development that promotes field of metallurgy is the basic task that promotes China's modernization construction.
In the pyrometallurgy field, smelting can produce the great amount of high-temperature molten slag when obtaining metal, and contains a large amount of valuable metals in the slag.With the copper smelting by pyrometallurgy is example: obtain in the process of matte with the sulphide ore smelting, cupric all surpasses 0.6% in the slag, even reaches 2.5%, will cause the great wasting of resources if discard, and therefore must the slag that metallurgy produces be recycled.
Reclaim in the technology at existing slag, with after the slag slow cooling again flotation be effective method, this kind arts demand is temporarily stored in slag in the slow cooling cinder ladle.The volume of slow cooling cinder ladle is basically at 11m at present
3About, method in common can be described below.
Slag is discharged through chute by the floss hole of smelting furnace and is flowed directly in the slow cooling cinder ladle, when the slag liquid level in the slow cooling cinder ladle meets the requirements of height, with the floss hole shutoff of smelting furnace.Because receive the restriction with hyperthermia radiation of splashing of slag stream, transporting equipment can only only just can be carried out the more operation of changing-over cinder ladle after the shutoff at floss hole fully away from discharge region, discharge process must be interrupted operation.The cinder ladle that then will fill slag by transporting equipment shifts out and connects the slag position, empty cinder ladle is put into to connect on the slag position again, opens floss hole again and discharges again and accomplish a slag emission cycle.
Yet in the process of prior art slag emission, the time of replacing cinder ladle, keying floss hole is grown and causes the slag emission cycle longer.In order as early as possible the slag in the smelting furnace to be discharged, only take the method for a plurality of floss holes operation simultaneously to satisfy the production demand in the production.Yet, open floss hole and all adopt the method for burning oxygen usually, serious to the refractory brick damage at floss hole place, and then to causing adverse effect the service life of smelting furnace.Simultaneously, contain a certain amount of pernicious gas in the slag emission process, many mouthfuls intermittent discharge, the burden of increase pernicious gas treatment system, and the flue gas rate of recovery is low, and heat energy can't be recycled.
Therefore, how to avoid opening and closing floss hole so that change cinder ladle, and long problem of the slag emission time that causes becomes those skilled in the art's important technological problems to be solved because of frequent.
The utility model content
