Aluminum Alloying Additive Tablets

Resources

In order to improve the properties of aluminum, it is necessary to add various alloy elements to make different grades of alloy. At present, alloy or pure metal is basically used in China. Some domestic aluminum processing plants have replaced the master alloys with aluminum alloy additives. From the application effect, it can be seen that the additives not only have all the advantages of the master alloys, but also overcome some disadvantages of the master alloys, so the additives are more and more widely used.

 

Product advantages of aluminum alloying additive tablets

Aluminum alloying additive tablets is much better than master alloys because of its good adding mechanism, convenient use method, the stable actual yield of elements, and economic production mode.It avoids excessively high temperature, which leads to the reduction of the life of the smelting furnace, and increases the burning loss of aluminum and alloy elements. The smelting productivity is also reduced, worsening the working conditions. What's more serious is that the composition of the master alloy is uneven, which brings a series of difficulties to the control of alloy element content in the future.


Instructions of using aluminum alloying additive tablets

Aluminum alloying additive tablets can be directly added to the melting furnace or holding furnace but must be added before refining. In order to achieve the expected actual yield of alloy elements, other matching requirements are needed.The details are as follows:

Due to the pure metal addition mechanism, the absorption rate of alloy elements always increases with the increase of temperature. Field experience shows that aluminum alloy additive tablet is sensitive to temperature, especially SY-Mn. The temperature of liquid aluminum should be controlled at 740 ± 10℃, otherwise, the time of metal absorption will be prolonged.
