The advantages and functions of casting Ferro Silicon Barium
The use of Ferro Silicon Barium is the same as that of calcium, but the reaction of the barium element in silica-barium with oxygen occurs after the reaction of calcium and oxygen. The advantage of adding barium is that the activated core containing barium is stable over a long period of time and makes the inoculation material more resistant to decay, with the result that the inoculation material can last more than 20 minutes.
Casting silicon barium casting silicon barium
When casting the advantage of adding silicon barium is containing barium activated nuclear is stable for a long time, and make the material more resistant to decay, as a result can be silicon barium material for 20 minutes or more, silicon barium this breeding material in casting of large parts and often delay lines is very useful, barium and calcium to form a kind of easy to remove slag, due to keep the main containing barium slag in the ladle, making it easy to keep the stopper and casting machine clean.
Though is to use silicon barium used for casting can produce a large amount of slag ladle on the surface, but this is only an illusion, because slag in the ladle, rather than being transferred to the automatic casting machine, therefore, it is necessary to carry out the ladle more cleaning and maintenance, however, most of the foundry will find this is a better, cleaner and cheaper choice, rather than replace the stopper and casting machine, the cleaning effect is the stopper and casting machine internal relatively clean, long service life, due to the silicon barium can promote and improve the graphite nucleation, including barium breeding materials become is the effective means to get rid of the white matter.
From this courseware casting put Ferro Silicon Barium really big effect, its advantage is that it can play a good deoxidizing inoculation effect, but also can improve the graphite distribution in molten iron to improve casting quality, especially in the production of graphite casting using silica-barium advantage and effect is more obvious!
