Brief Introductio
Recarburiser (also known as carbon raiser) is used to adjust the carbon content in molten iron or steel during the steelmaking and foundry process. Our recarburiser is manufactured from high-quality calcined anthracite coal and graphite petroleum coke, ensuring high carbon recovery, low sulfur, low nitrogen, and fast absorption.
