[0002] Before the aluminum plate is cast and rolled, the degree of purification of its melt directly affects the quality of the processed aluminum products. Hydrogen embrittlement will occur when the hydrogen content in the aluminum is only about 0.1ml / 100g, and excessively high hydrogen content will cause great harm to the subsequent deep processing. This requires a very high degree of purification of the aluminum melt, and the purification method of the aluminum melt becomes particularly important. However, the existing aluminum cast and rolled degassing box has a complex air intake structure, the baffle in the box is not convenient to adjust, the air flow on both sides of the baffle is difficult to conduct, and the surface of the diffuse air-permeable bricks at the bottom of the box is easy to adsorb impurities, affecting the degassing efficiency of the device. Therefore, it is urgent to improve it.
