铝水除气箱

除气箱:在线除气设备又除气箱体、除气转子、耐火内衬、加热系统、驱动系统、提升和扒渣机构、惰性气体系统、氯气系统、控制系统、流槽口等组成。

在线除气设备的主要用途是用来除去熔体中的气体(氢气)和有害杂质。原理是熔体铝液通过流槽流经除气箱体,外界惰性气体(如氩气等)和氯气通过旋转的转子喷入铝液中,形成大量弥散的小气泡,熔体中氢分压促使氢向小气泡中扩散,同时,随小气泡浮到熔体表面把氢带出熔体,达到除氢的目的,并且气泡上浮过程中依靠气体表面的张力把一部分夹渣带出熔体。

除气设备的第二功能是通过旋转喷头在熔体中搅拌,使熔体中的合金元素更加均匀化。除气设备有插入式加热器,加热效率高。


Degassing box: The online degassing equipment consists of a degassing box body, degassing rotor, refractory lining, heating system, driving system, lifting and slag removal mechanism, inert gas system, chlorine gas system, control system, flow channel port, etc.

The main purpose of online degassing equipment is to remove gases (hydrogen) and harmful impurities from the melt. The principle is that the molten aluminum flows through the degassing box through the flow channel, and the external inert gas (such as argon, etc.) and chlorine gas are sprayed into the aluminum through the rotating rotor, forming a large number of dispersed small bubbles. The hydrogen partial pressure in the melt promotes the diffusion of hydrogen into the small bubbles, and at the same time, it floats to the surface of the melt with the small bubbles to carry the hydrogen out of the melt, achieving the purpose of hydrogen removal. During the upward movement of the bubbles, a part of the slag is carried out of the melt by the tension on the gas surface.

The second function of the degassing equipment is to stir the alloy elements in the melt by rotating the nozzle, making the alloy elements in the melt more uniform. The degassing equipment has a plug-in heater with high heating efficiency.
