Description
Technical Field
The utility model relates to an intermediate frequency furnace smelts equipment for the production line, more specifically says, especially relates to a molten iron balling device with splashproof structure.
Background
An intermediate frequency furnace, which is called an intermediate frequency induction furnace, is a device for converting power frequency 50HZ alternating current into intermediate frequency (more than 300HZ to 1000HZ), and is widely used for smelting nonferrous metals and ferrous metals. Compared with other casting equipment, the medium-frequency induction furnace has the advantages of high heat efficiency, short smelting time, less burning loss of alloy elements, wide smelting material, less environmental pollution, capability of accurately controlling the temperature and the components of molten metal and the like. When the intermediate frequency furnace is used for smelting, a large amount of high-temperature dust and smoke can be generated, and if the high-temperature dust and the smoke are not effectively treated, the temperature of a production workshop can be rapidly increased, and the physical health of workers can be seriously influenced.
At present, after the conventional intermediate frequency furnace is smelted, molten iron is hoisted to a spheroidizing chamber through a molten iron transfer barrel and is spheroidized through a spheroidizing wire feeder, and then the molten iron is subpackaged into a pouring hopper for pouring. In this way, the process is troublesome, and a corresponding sealing structure is required to be arranged on the molten iron transfer barrel to collect the smoke dust when the molten iron is spheroidized. There are two main conventional ways: one is to set up a sealable space in the balling chamber, while feeding the wire balling, hang the ladle into sealable space, the balling wire feeder penetrates the space and stretches into the molten iron to spheroidize through the aperture, the sealed space collects the smoke and dust produced while balling through the smoke and dust collecting system at the same time; the second method is that during spheroidization, a fixed ladle cover close to the molten iron transfer barrel in size is manufactured, the ladle cover is provided with an opening and is provided with an air pipe for collecting smoke dust, core-spun yarns sent out by the spheroidizing wire feeder can pass through the ladle cover through a fixed wire outlet guide pipe and enter the molten iron transfer barrel, during spheroidization, the molten iron transfer barrel is placed on a movable flat car, the flat car is moved to the lower part of the ladle cover, the ladle cover is lowered or lifted, the molten iron ladle and the ladle cover are closed, and then the wires are fed, spheroidized and the smoke dust is collected. The first wire feeding mode can form a large closed space, so that a large amount of air is needed to collect smoke dust, and the energy consumption is high. The amount of wind required by collecting the smoke dust in the second mode is less, but a flat car and a device for lifting the flat car or lifting the ladle cover need to be added, so that the cost is high, the core-spun wire outlet conduit can be blocked by excessive collection of the smoke dust, and the cleaning is inconvenient.
