- **Caution**: 

### Q: What is the primary function of a desulfurization reactor in basic metal manufacturing?
**A**: The desulfurization reactor removes sulfur impurities from hot metal through chemical treatment using injected reagents and mechanical agitation, improving metal quality and preventing brittleness.

### Q: What materials are used in constructing a desulfurization reactor?
**A**: Key materials include a refractory lining (alumina or magnesia-carbon) for thermal resistance, a pressure vessel grade steel shell for structural integrity, and high-temperature alloy components for the stirring mechanism.

### Q: How does the stirring mechanism work in a desulfurization reactor?
**A**: The stirring mechanism, typically an impeller or gas purging lance, agitates the molten metal to ensure thorough mixing of desulfurization reagents, maximizing sulfur removal efficiency and reaction kinetics.
