Abstract Based on the smelting practice of low-sulfur steel, such as J55, L360, the sulfur control technology during the process of “hot metal predesulfurization-converter-LF refining-continuous casting” was analyzed. The key processes of sulfur control are hot metal predesulfurization, converter and LF refining. By using the sulfur control technology during the whole process, the low-sulfur content steel are produced, and among them, the lowest sulfur content is 0.002%.
