# Industrial Specification: Molten Metal Distribution System

## 1. Technical Definition
A system that precisely controls and distributes molten metal from the melting furnace to the continuous casting mold.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 bar pressure differential across distribution nozzles, 700-750°C metal temperature, 0.5-3.0 m/s flow velocity**. Failure boundary: **Pressure drop below 0.5 bar causes flow stagnation and solidification, temperature below 680°C initiates premature solidification, velocity exceeding 4.0 m/s causes refractory erosion**, Mechanism: **Stefan-Boltzmann radiation heat loss (σ=5.67×10⁻⁸ W/m²K⁴) combined with Newtonian cooling (h=50-100 W/m²K) causes temperature decay; Bernoulli principle (P + ½ρv² = constant) governs pressure-velocity relationship with molten steel density ρ=7000 kg/m³**.

### 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.
