MgPro 100 serves to provide protective cover for spheroidizers used for ladle treatment by means of the sandwich process. Traditionally, iron chips and steel shavings have been used for this purpose.
MgPro 100 is a powder whose color ranges from grey to black. When used, it does not generate fume and does not affect negatively molten iron. It is not hazardous for personnel.
A batch of a spheroidizer is fed into a ladle, it is then covered with a uniform layer of MgPro 100, after which molten metal is poured into the ladle.
The cover material makes it possible to:
- reduce metal heat losses from the melt in the ladle, which will make it possible to lower energy consumption
- optimize consumption of the spheroidizer being used as it allows the modification process to proceed calmly
- improve the iron foundry environment as it reduces generation of flame and fume that accompany interaction of molten metal and magnesium.
Consumption depends on the capacity of the treatment ladle and the size of the spheroidizer being used and may be between 4 and 7 kg per 1 ton of molten iron.
