# Industrial Specification: Continuous Casting Mold Powder

## 1. Technical Definition
Granulated flux material for continuous casting molds in steel production.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 g/cmÂ³ bulk density, 1100-1300Â°C melting temperature, 0.8-1.5 PaÂ·s viscosity at 1300Â°C**. Failure boundary: **Viscosity drops below 0.3 PaÂ·s at 1300Â°C or exceeds 2.5 PaÂ·s at 1300Â°C, thermal conductivity falls below 1.0 W/mÂ·K or exceeds 3.5 W/mÂ·K**, Mechanism: **Phase separation of CaO-SiOâ‚‚-Alâ‚‚Oâ‚ƒ ternary system causing viscosity breakdown, crystallization of cuspidine (3CaOÂ·2SiOâ‚‚Â·CaFâ‚‚) altering thermal properties, Marangoni convection disrupting slag film uniformity**.

### 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 purpose of continuous casting mold powder in steel production?
**A**: Continuous casting mold powder acts as a flux material that lubricates the mold, controls heat transfer, absorbs inclusions, and prevents oxidation during the steel casting process, ensuring smooth surface quality and preventing defects.

### Q: How does the basicity index affect mold powder performance?
**A**: The basicity index (ratio of basic to acidic oxides) determines the melting behavior and viscosity of the mold powder. Higher basicity typically results in lower viscosity and better lubrication, while affecting slag formation and heat transfer control in the mold.

### Q: Why is carbon content important in continuous casting mold powder?
**A**: Carbon content controls the melting rate and insulation properties of the mold powder. It helps maintain a consistent liquid slag layer, prevents premature melting, and regulates heat transfer between the steel strand and mold for optimal solidification.
