# Industrial Specification: Metal Outlet

## 1. Technical Definition
A discharge opening in a separation chamber or launder system designed for controlled release of molten metal or metal-bearing materials.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-0.5 bar pressure differential, 700-1200°C temperature range, 0.5-3.0 m/s flow velocity**. Failure boundary: **Thermal stress exceeds yield strength of refractory material (σ_yield &gt; 25 MPa at 1200°C), erosion depth &gt; 15mm refractory lining, solidification temperature drop below 650°C**, Mechanism: **Thermal fatigue from cyclic heating/cooling (ΔT &gt; 300°C) causing refractory spalling, erosion-corrosion from high-velocity molten metal flow (&gt;3.5 m/s), solidification-induced blockage from temperature drop below liquidus point**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Refractory thermal expansion mismatch (α_refractory = 6.5×10^-6/°C vs α_steel = 12×10^-6/°C) | 8 | Refractory lining cracking and spalling | Graded refractory design with intermediate expansion layers, controlled preheating at 50°C/hour to 800°C |
| Alumina (Al₂O₃) buildup from metal oxidation at oxygen partial pressure &gt; 10^-8 atm | 8 | Outlet blockage reducing flow area by &gt;40% | Argon inert gas purging at 5-10 L/min, ceramic coating with &lt;5% porosity |

- **Caution**: 
- **Caution**: 

### Q: What materials are used in metal outlet construction?
**A**: Our metal outlets feature refractory-lined steel or high-temperature alloy steel construction to withstand extreme temperatures and corrosive molten metal environments.

### Q: How does the outlet ensure controlled metal discharge?
**A**: The precision-engineered outlet nozzle and refractory lining work together to regulate flow rates, prevent splashing, and maintain consistent discharge for optimal process control.

### Q: What maintenance is required for metal outlets?
**A**: Regular inspection of refractory lining wear, cleaning of nozzle obstructions, and checking mounting flange integrity ensure long-term performance and safety.
