# Industrial Specification: Separation Chamber / Launder

## 1. Technical Definition
A component within a Slag Separation Unit designed to facilitate the separation of molten slag from metal through controlled flow and settling.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-0.5 m/s flow velocity, 1200-1500°C temperature, 0.5-2.0 m³/min throughput**. Failure boundary: **Flow velocity exceeding 0.8 m/s causes turbulent mixing preventing separation, temperature below 1150°C causes slag solidification, temperature above 1550°C causes refractory erosion &gt;5 mm/hour**, Mechanism: **Stokes' law settling failure at Reynolds number &gt;2000, refractory spalling due to thermal expansion coefficient mismatch (α_refractory=6.5×10⁻⁶/K vs α_shell=12×10⁻⁶/K), slag viscosity reduction below 0.5 Pa·s causing boundary layer disruption**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

- **Caution**: 

### Q: What is the primary function of a separation chamber in basic metal manufacturing?
**A**: A separation chamber, also called a launder, facilitates the separation of molten slag from metal through controlled flow and settling processes within a slag separation unit, improving material purity and recovery efficiency.

### Q: Why is refractory lining important for slag separation chambers?
**A**: Refractory lining protects the steel structure from extreme temperatures (often exceeding 1500°C) and corrosive properties of molten slag and metal, ensuring durability and preventing contamination of processed materials.

### Q: How does the flow control weir optimize slag-metal separation?
**A**: The flow control weir regulates the velocity and depth of molten material flow, allowing sufficient residence time for slag and metal to separate by density differential, resulting in cleaner metal recovery and efficient slag removal.
