Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Examples
As shown in figure 1, the tapping system of the silicon-manganese furnace of the utility model comprises a furnace body 1, a tapping device 10, a tapping device and a dust removing device. The tapping device 10 is arranged on the furnace body 1, the tapping device is connected with the tapping device 10, and the dust removal device is arranged above the tapping device 10.
As shown in fig. 2 to 4, the tapping device 10 includes a base 13 connected to the furnace body 1, two side plates 11 respectively disposed at both ends of the base 13, a tap hole 15 disposed on the furnace body 1 and located between the two side plates 11, and a baffle plate 12 installed between the two side plates 11 and capable of moving up and down along the side plates 11. Specifically, the two side plates 11 are parallel to each other, and the baffle 12 is close to the furnace body 1 so as to block molten iron; the two side plates 11 are provided with sliding grooves, two ends of the baffle 12 are respectively positioned in the sliding grooves on the two side plates 11, and the baffle 12 can slide up and down along the sliding grooves.
At least two grooves 14 are formed in the base 13, the grooves 14 extend to the end of the base 13, the grooves 14 are located between the two side plates 11, and a convex portion 16 is formed between every two adjacent grooves 14, in this embodiment, the number of the grooves 14 is two.
During tapping, the molten iron is discharged from the tapping hole and flows to the iron flowing device from the groove on the bottom plate, and due to the blocking effect of the side plates and the baffle plate, the high-temperature molten iron cannot splash remotely, so that safety accidents caused by splashing of the high-temperature molten iron are effectively prevented.
