In addition, the cylindrical blast furnace cover setting makes the electrode into the furnace at a poor depth and the unit power consumption is high. Utility Model Content

[0006] A further technical solution is that the furnace cover is a tower-shaped short furnace cover, and the height of the furnace cover is 1500 mm.

[0007] A further technical solution is that an inspection cover is provided between every two electrode holes on the furnace cover.

[0008] A further technical solution is that a circular material column is provided on each of the inspection covers, and a circular material column is provided directly in front of each electrode hole on the furnace cover, and the top of the circular material column is connected to a material bin through a material pipe.

[0009] A further technical solution is that there are fifteen silos and fifteen kidney-shaped silos, six of which are double silos.

[0010] A further technical solution is that three water-cooling hangers are distributed around each electrode hole on the furnace cover.

[0011] A further technical solution is that a water ring is fixedly installed on the top of the furnace body.

[0012] A further technical solution is that an insulating plate is provided between the furnace body and the furnace cover.

[0013] A further technical solution is to provide a raw gas flue and a clean gas flue inside the furnace cover.

[0014] Compared with the prior art, the beneficial effects of the utility model are:
