Our KARBURITs are recarburisers that dissolve in melt to increase the carbon content. They are used to carburise the melt of iron alloys and steel.
KARBOSIL is used to add silicon and to carburise the melt in induction furnaces. It is also used in production of synthetic alloys, where lower sulphur and nitrogen values are required.
The inoculation of grey cast iron is a process where melt is added to an agent to cause changes in crystallisation during the setting of the melt. These expected, due to changes in chemical composition contain elements with strong desulphurisation and deoxidization action (aluminium, calcium, barium, magnesium, strontium or zircon). Products of melt deoxidization with these elements represent new crystallisation nuclei for graphite deposition.
