# Industrial Specification: Molten Metal Desulfurization Reactor

## 1. Technical Definition
A system for removing sulfur from molten metals using chemical reagents.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 bar injection pressure, 1450-1550°C metal temperature, 0.5-2.0 m³/min argon flow rate**. Failure boundary: **Injection pressure exceeds 1.5 bar causing refractory erosion, metal temperature drops below 1420°C causing reagent solidification, argon flow exceeds 2.5 m³/min causing excessive splashing**, Mechanism: **High-velocity reagent injection at &gt;1.5 bar causes refractory wear via particle abrasion (erosion rate &gt;2 mm/hour at 1550°C), temperature below 1420°C causes CaC₂ solidification (melting point 2160°C but forms low-melting eutectics), excessive argon flow creates turbulent splashing exceeding 15% metal loss**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
