Description

Automatic burning-through device of ferrosilicon furnace

Technical Field

The utility model relates to a burn and wear ware technical field, concretely relates to automatic device of wearing of burning of ferrosilicon stove.

Background

The burnthrough device is a main hole opening tool for ferrosilicon smelting, and the burnthrough device is special equipment for producing a submerged arc reduction electric furnace of ferroalloy by using an electric arc to burn an iron outlet. When the electric arc furnace works, the cable energizes the burnthrough device, a worker holds the handle to enable the front end of the burnthrough device to be close to the iron outlet, the carbon rod electrode generates electric arc at the iron outlet, and the iron outlet is burnt by utilizing the high temperature of the electric arc. The ware that burns that present electric stove used, whole mostly are the solid member of welding, and the heat can pass through whole equipment very fast, and the ware that burns self heat dissipation cooling very slow for this kind of ware that burns is very hot when using, leads to on the one hand to burn the ware equipment live time and shortens, and on the other hand workman's operating environment is very poor. When the flow of molten iron is large, the high-temperature molten iron is directly contacted with the burnthrough, and the service life of the burnthrough is shortened. The burner is used as an important tool for discharging ferrosilicon, and leads high-temperature electric arc to open a channel, namely a furnace eye, flowing from a ferrosilicon molten pool to the outside on the ferrosilicon furnace according to the principle that electric arc is generated by electric current through gas conduction, so that molten ferrosilicon smoothly flows out of the ferrosilicon furnace. At present, all the burnthrough devices used by the ferrosilicon furnace are hung on an I-shaped steel rail fixed at the upper end of a tapping platform, and if the I-shaped steel rail is not firmly fixed, tapping burnthrough workers can be injured by crashing after falling, so that the tapping danger is increased. In addition, when the suspended type burnthrough device is used for opening holes, manual push-pull is needed, the labor is extremely high, and the labor intensity of a ferrosilicon tapping worker is increased. After the burnthrough device is used, the burnthrough device needs to be pulled out manually and transversely rotated to a proper position to be placed, the temperature of a carbon rod at the front end is up to two thousand degrees centigrade, and the red carbon rod is easy to break in the rotating process, injure and burn workers out of the furnace. The original burner is connected with the ferrosilicon furnace transformer through a burner copper bar and is connected with a secondary short net of the transformer. Each ferrosilicon furnace is provided with 3 furnace discharging platforms, and the burnthrough devices are respectively arranged at the positions of transformer bearing columns close to the furnace discharging platforms. The original burner mainly comprises an insulating layer, a rotary screw and an insulating handle; the screw rod is rotated manually, and the power-on and power-off operation is realized through the front and back actions of the screw rod, so that the operation is very inconvenient.

With the gradual increase of labor cost, the trend of replacing human work by automatic machines is already becoming a trend.
