# Industrial Specification: Water-Cooled Copper Mold

## 1. Technical Definition
A copper mold with internal water cooling channels used in continuous casting to solidify molten steel into a specific cross-sectional shape.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-2.5 MPa (8-25 bar) water pressure, 15-35°C inlet temperature, 0.5-3.0 m/s water velocity**. Failure boundary: **Copper temperature exceeds 350°C (recrystallization threshold), water pressure drops below 0.5 MPa (5 bar) causing flow separation, thermal gradient exceeds 200°C/cm across mold wall**, Mechanism: **Thermal fatigue from cyclic stress (Δσ &gt; 150 MPa) due to 1200°C molten steel contact alternating with 30°C cooling water, causing crack initiation at grain boundaries; cavitation erosion when local pressure drops below water vapor pressure (2.34 kPa at 20°C) in high-velocity zones**.

### 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.

- **Caution**: 

### Q: What are the advantages of water-cooled copper molds in continuous casting?
**A**: Water-cooled copper molds provide rapid and uniform heat extraction, ensuring consistent solidification of molten steel, reducing defects, and extending mold life through efficient cooling.

### Q: What materials are typically used in water-cooled copper molds?
**A**: The primary material is copper, often alloyed with chromium or silver for enhanced thermal conductivity and durability, while stainless steel is used for structural components like backplates and support structures.

### Q: How does the water cooling system work in these molds?
**A**: The system features internal water channels or jackets that circulate cooling water through the mold, absorbing heat from the molten steel to control solidification rates and maintain optimal casting conditions.
