ABSTRACT:
A method of manufacturing a metallurgical addition agent, especially an agent comprising silicon carbide fines, comprises a first step of forming a mix of at least 30% fines, cement and at least 20% water. The next step comprises pressing the wet mix in a mold while squeezing out excess water but leaving sufficient water for hydration of the cement. The pressed shapes are cured at ambient temperatures.
