Once the thin slag formed, add silicon carbide for reduction, its quantity is decided by the actual amount of molten steel in the furnace and the furnace views conditions. 3. Speed up the reaction rate, shorten the refining time, in the meantime, it will also cause desulfurization effect.
Therefore, this part of ISO 21068 covers the full range of analysis from pure silicon carbide to oxidic refractory composition with a low content of silicon carbide and/or nitrides. Primarily, this part of ISO 21068 provides methods to distinguish between different carbon bound types like total carbon (C total ) and free carbon (C free ) and derives from these two the silicon carbide content.
