An air lock device for an aluminum melt degassing box and the degassing box thereof

Abstract

The invention discloses an airlock device of an aluminum melt degasification tank and the degasification tank. The airlock device comprises an airlock, a separation wall, an upper channel and an aluminum feeding chamber, wherein the airlock is composed of the separation wall, the upper channel and the aluminum feeding chamber; the separation wall is located at the boundary of a box cover and a boxbody and composed of a horizontal wall and an inclined wall; the upper channel is arranged in an inner space composed of the separation wall and extends along the separation wall, the lowermost position of the upper channel is provided with a horizontal lower port, and the lower port is inserted into the position below the liquid level inside the box body; and the aluminum feeding chamber communicates with the upper channel through a communicating opening which is higher than the lowermost face of the aluminum feeding chamber. The airlock is made of high-aluminum refractory bricks. The included angle between the horizontal wall and the inclined wall is 110 degrees. The vertical distance between the lower port and the liquid level is 30mm. By adopting the airlock device of the aluminum melt degasification tank and the degasification tank, external air cannot be brought into the degasification tank, the product quality is improved, and disturbance to the liquid level in the molten aluminum adding process is small.

Description

technical field [0001] The invention relates to the field of degassing boxes, in particular to an air lock device of an aluminum melt degassing box and the degassing box thereof. Background technique [0002] The aluminum melt degassing box is an online equipment for aluminum and aluminum alloy melts in the casting process. Its function is to greatly reduce the hydrogen content in the melt and improve the quality of aluminum and aluminum alloy cast locks. In the process of refining and degassing in the degassing box, the oxygen content in the furnace chamber will often increase due to the escape of outside air, and the water vapor will also increase. At the same time, the temperature of the furnace chamber will also be reduced. reduced, affecting the quality of the product. Contents of the invention [0003] The problem to be solved by the present invention is to provide an air lock device for an aluminum melt degassing box and its degassing box, which will not bring in o...
