# Industrial Specification: Melt Surge Tank

## 1. Technical Definition
A specialized tank designed to temporarily store and regulate the flow of molten ammonium nitrate within a continuous production system, preventing pressure surges and ensuring stable operation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 MPa (5-20 bar) at 170-185°C**. Failure boundary: **3.5 MPa (35 bar) internal pressure or 250°C wall temperature**, Mechanism: **Thermal decomposition of ammonium nitrate at 210°C producing N₂O gas causing rapid pressure increase exceeding yield strength of 316L stainless steel (205 MPa)**.

### 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.

| Symbol | Variable Definition | Localized Reference |
