GeneralDescription:
Mn Tablets is a new material substitutefor master alloys. It is pressed by pure metal powder and additives, accordingto a certain proportion after homogeneous mixing. It could adjust Mn contentsof different kinds of aluminum alloys, which could lower the meltingtemperature.
Applications:
1. Additives for master alloys.
2. Alloying additives for materials ofautomobile, ship building and Airspace Industries.
Advantages:
1) Simplify aluminium melting process
2) Save energy and raw materials,cost
3) Prior control alloy content, improvequality
4) high metal content, small-sized,easy tostore and use
Instructions For Use :
According to alloying element content ofalloy brand and results of bath analysis, as 95% actual yield count thequantity of Mn additive. After slagging off ,spray it to aluminum pooldirectly and evenly, after flammule disappeared and 20-30minutes standing, shouldenhance hand stirring for 5 minutes, make it uniform diffusion. And accordingto actual condition,assure some time to diffusion.
1)Use temperature:745°C±5°C
2)Quantity added(kg)=alloying element content-bathanalysis element content)X outfit furnace quantity(kg)÷actual yield 95% X additivealloying element content 3)melting time :20min-30min
