For perfect refining of alloys, FONDERMAT INDUSTRY offers its solutions:
The objective of refining is to modify the crystalline structure during solidification, to obtain an alloy with the finest grain size possible. The presence of a very fine structure guarantees essentially two things:
In hypereutectic alloys, the primary silicon refining treatment is frequently preferred to the modification treatment, which is achieved through the addition of phosphorous, with a content of 0.003-0.015%, based on the silicon content and the cooling rate.
