Calcium carbide crystals is a powerful, fast-acting desulfurizer. When injected into molten steel or hot metal using a carrier gas (typically nitrogen or argon), CaC₂ decomposes and reacts vigorously with dissolved sulfur. Calcium carbide crystals is the most cost-effective and efficient desulfurizing agent for steel mills, playing an irreplaceable role in producing high-quality steel. As a powerful reducing agent, it boasts strong affinity for sulfur, enabling rapid and thorough desulfurization of molten steel to meet strict industry standards.
