                除氣機 Fixed Casting Degasser

                固定▓式除氣機

                 固定式鑄造除氣裝置適用於燒鑄,采用氬氣或氮氣作為精煉介質,從鋁熔體中去除氫、金屬及非金屬夾雜物的爐外精煉設備;
                    固定式鑄造除氣裝置安裝於固定位置,用移動澆包的方式進行工作,通過高速旋轉的石墨子將定量的精煉氣體帶入熔體中。通過石墨轉子與鋁液的相對高速剪切,產生細小的氣泡並均勻分布在鋁熔體中。由於氣泡中氫分壓為零,鋁熔體中的氫分壓高,鋁液中的氫漸漸向氣泡中擴散。同時,鋁液中的金屬及非金屬夾雜物被吸附在氣泡表面,氣泡及夾雜物上浮,從而達到去除鋁液中氫及夾雜物的目的。

                流槽式在線除氣機
                    除氣效率高:裝置采用了多級除氣的設計,在流槽中采用了三個石墨轉子進行除氣,在除氣箱內形成大量的對流,使小氣泡在鋁液中可以得到充分的擴散。增大了氣泡和鋁液的接觸面;同時除氣箱體采用了密封式設計,杜絕了外界空氣的進入而造成二次汙染。大大的提高了設備的除氣效率。
                使▓用成本低:除氣裝置采用了流槽除氣的方法,取消了在線精煉設備所必須的鋁液加熱保溫系統,最大限度的降低了設備使用過程中的電耗;同時由於采用流槽除氣,殘留鋁液量較少,減少了金屬的損耗。
                便於合金的快速轉換:除氣裝置采用了▓流槽除氣,每一個鑄次結束以後,都可以將除氣箱內的殘留鋁液放光,極大地方便了合金的快速轉換,免除了合金轉換時對除氣裝置的洗爐。可以減低金屬損耗和提高生產效率。

                 

                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.
