Description

Technical Field

[0001] The utility model belongs to the technical field of automatic furnace tamping devices, and in particular relates to an automatic furnace tamping device for smelting silicon-aluminum-calcium-barium alloy. Background Art

[0002] Silicon, aluminum, calcium and barium are the best deoxidizers and desulfurizers in barium-based alloys, which can reduce the oxygen in steel to a minimum. At the same time, the complex oxides containing calcium, barium, silicon and aluminum are easily floated from the molten steel, purifying the molten steel and improving the impact resistance and processing properties of the steel. In the process of smelting silicon, aluminum, calcium and barium, a tamping device is required to add and tamp the materials inside the furnace.

[0003] At present, the existing automatic furnace tamping devices used in the smelting process of silicon-aluminum-calcium-barium alloy are mostly driven by a vehicle body. During the tamping process, the vehicle body will move backward due to the impact force, which is not conducive to continuous operation. In addition, since the rubber wheels are close to the furnace body, they are in contact with the high-temperature ground for a long time, which may cause the wheels to melt or the tires to explode, which is very dangerous. For this reason, we propose an automatic furnace tamping device for smelting silicon-aluminum-calcium-barium alloy. Utility Model Content
