# Industrial Specification: Distribution Launder

## 1. Technical Definition
A channel or trough designed to direct and control the flow of molten metal from a furnace or holding vessel to various casting stations or molds within a foundry or metal processing facility.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s flow velocity, 700-1600°C molten metal temperature, 0.1-0.5 MPa internal pressure**. Failure boundary: **Thermal stress exceeding 250 MPa yield strength at refractory-metal interface, flow velocity exceeding 3.0 m/s causing refractory erosion, temperature exceeding 1650°C causing refractory decomposition**, Mechanism: **Thermal fatigue from cyclic heating/cooling (coefficient of thermal expansion mismatch: refractory 5.5×10⁻⁶/°C vs steel 12×10⁻⁶/°C), refractory erosion from turbulent flow (Reynolds number &gt;4000), creep deformation at sustained temperatures &gt;1400°C**.

### 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.
