The aluminum liquid rotary degasser is an online device for aluminum and aluminum alloy melts in the casting process, and its function is to greatly reduce the hydrogen content in the aluminum liquid and improve the quality of aluminum and aluminum alloy products. During the degassing process of the degassing box, the oxygen content in the furnace chamber will often increase due to the escape of outside air, and the moisture will also increase, and the temperature of the furnace chamber will also be reduced at the same time. These factors will reduce the effect of hydrogen removal. , affecting the quality of the product.
In addition, the existing aluminum liquid rotary degasser inlet and outlet are at the same height, and the process of degassing and slag removal of aluminum liquid is carried out in the cavity, and there is also a large amount of aluminum liquid in the cavity after use, and these aluminum liquids only The cavity can be discharged through the slag discharge port of the degassing box and become waste aluminum, which greatly reduces the yield of aluminum in the production process. And after the cavity is used, solidified aluminum blocks and aluminum slag are easy to deposit in the box, which is not easy to remove. After the liquid aluminum degassing box is used once, the residual aluminum liquid is about 1-2 tons, which is especially unbearable for small furnaces and aluminum liquid casting experimental lines.
Utility model content
