# Industrial Specification: Secondary Cooling Chamber

## 1. Technical Definition
A controlled cooling zone in continuous casting systems that precisely regulates the solidification rate of non-ferrous alloy strands after initial solidification.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Temperature: 200-450°C, Cooling rate: 0.5-3.0°C/s, Water flow: 15-60 m³/h, Pressure: 2.5-6.0 bar**. Failure boundary: **Thermal gradient exceeds 8.0°C/mm across strand cross-section, Water flow drops below 12 m³/h for &gt;30 seconds, Chamber temperature exceeds 480°C**, Mechanism: **Thermal stress-induced cracking due to excessive cooling rate differentials (exceeding 2.5°C/s/mm gradient), Nucleate boiling transition to film boiling at heat flux &gt;1.2 MW/m² causing Leidenfrost effect and loss of cooling efficiency**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.
