# Industrial Specification: Continuous Casting Mold Flux

## 1. Technical Definition
Powdered material for steel continuous casting mold protection and lubrication

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 g/cmÂ³ powder density, 1100-1300Â°C melting temperature, 0.3-0.6 PaÂ·s viscosity at 1300Â°C**. Failure boundary: **Viscosity &lt;0.2 PaÂ·s causes excessive mold infiltration, viscosity &gt;1.0 PaÂ·s causes lubrication failure, basicity ratio (CaO/SiOâ‚‚) &lt;0.8 leads to crystallization failure**, Mechanism: **Stefan-Boltzmann radiation heat transfer (Ïƒ=5.67Ã—10â»â¸ W/mÂ²Kâ´) governs mold heat extraction; viscosity-temperature relationship follows Arrhenius equation Î·=Î·â‚€exp(Eâ‚/RT) where Eâ‚=150-250 kJ/mol for silicate melts**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

- **Caution**: 

### Q: What is the optimal basicity index for continuous casting mold flux?
**A**: The optimal basicity index (CaO/SiO2 ratio) typically ranges between 0.8-1.2, depending on steel grade and casting speed, to control viscosity and melting characteristics.

### Q: How does carbon content affect mold flux performance?
**A**: Carbon content (typically 2-10%) controls melting rate and provides lubrication. Higher carbon delays melting for deeper liquid pools, while lower carbon ensures faster melting for surface protection.

### Q: Why is free fluorine content controlled in mold flux formulations?
**A**: Free fluorine content is minimized (usually &lt;5%) to reduce environmental emissions and equipment corrosion while maintaining adequate fluxing properties through alternative components like alumina and silica.
