除气机 Fixed Casting Degasser

固定式除气机

 固定式铸造除气装置适用于烧铸,采用氩气或氮气作为精炼介质,从铝熔体中去除氢、金属及非金属夹杂物的炉外精炼设备;
    固定式铸造除气装置安装于固定位置,用移动浇包的方式进行工作,通过高速旋转的石墨子将定量的精炼气体带入熔体中。通过石墨转子与铝液的相对高速剪切,产生细小的气泡并均匀分布在铝熔体中。由于气泡中氢分压为零,铝熔体中的氢分压高,铝液中的氢渐渐向气泡中扩散。同时,铝液中的金属及非金属夹杂物被吸附在气泡表面,气泡及夹杂物上浮,从而达到去除铝液中氢及夹杂物的目的。

流槽式在线除气机
    除气效率高:装置采用了多级除气的设计,在流槽中采用了三个石墨转子进行除气,在除气箱内形成大量的对流,使小气泡在铝液中可以得到充分的扩散。增大了气泡和铝液的接触面;同时除气箱体采用了密封式设计,杜绝了外界空气的进入而造成二次污染。大大的提高了设备的除气效率。
使用成本低:除气装置采用了流槽除气的方法,取消了在线精炼设备所必须的铝液加热保温系统,最大限度的降低了设备使用过程中的电耗;同时由于采用流槽除气,残留铝液量较少,减少了金属的损耗。
便于合金的快速转换:除气装置采用了流槽除气,每一个铸次结束以后,都可以将除气箱内的残留铝液放光,极大地方便了合金的快速转换,免除了合金转换时对除气装置的洗炉。可以减低金属损耗和提高生产效率。

 

Fixed Casting Degasser

Fixed casting degassing device is the refining equipment outside of furnace  that suitable for casting, using argon or nitrogen as refining medium to remove hydrogen, metallic and non-metallic inclusions from the aluminum melt.

Fixed casting degassing installed at a fixed location, working by moving the ladle to get the quantitative refined gas into the melt through high-speed rotating Graphite rotor. By relatively high shear of graphite rotor and aluminum liquid to generate tiny bubbles and uniformly distributed in the aluminum melt. Because pressure of hydrogen in the bubble is zero, and its opposite in the aluminum melt, thus the hydrogen in the liquid aluminum gradually spread to the bubbles. Meanwhile, metal and non-metallic inclusions in the liquid aluminum are adsorbed on the surface of the bubbles, and inclusions are come-up with the bubbles, that leads to the result to remove the hydrogen and inclusions.

 

In-Line Launder Degasser

High efficieny: Device using a multi-stage degassing design, theres three graphite rotors to degas in the launder, thus form a large convection inside the degassing tank, and small bubbles can spread completely in liquid Aluminum. that increase the contact surface of the bubbles and liquid aluminum. Meanwhile degassing tank using a sealed design, put an end to the outside air get in and caused the secondary pollution, improve the efficiency of degassing.

Low cost: Device using the method that launder degassing to replace online refining equipment necessary for liquid aluminum heat insulation system, thus maximize the reduction of the device power consumption during use.In the mean time,as with the launder degassing, the residual liquid aluminum is less, that reduce the metal loss.

quick conversion: Device using launder degassing,it could empty the liquid aluminum after casting, Greatly facilitate the rapid conversion of alloys, Eliminating the wash for degassing device when alloy conversed. That could reduced metal loss and more productivity.
