# Industrial Specification: Inclusion Absorbers

## 1. Technical Definition
Functional additives within continuous casting mold flux designed to capture and remove non-metallic inclusions from molten steel.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 wt% in mold flux composition**. Failure boundary: **Below 0.3 wt% inclusion capture efficiency drops below 85%, above 2.5 wt% causes excessive slag viscosity exceeding 0.8 Pa·s at 1550°C**, Mechanism: **Inclusion absorption capacity saturation governed by Langmuir adsorption isotherm with maximum monolayer coverage at 2.0 wt%, beyond which excess additive forms separate phases disrupting slag structure**.

### 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**: 
- **Caution**: 

### Q: How do inclusion absorbers work in continuous casting mold flux?
**A**: Inclusion absorbers are functional additives in mold flux that chemically react with non-metallic inclusions in molten steel, capturing them into the slag layer to be removed, resulting in cleaner steel with improved mechanical properties.

### Q: What are the main materials used in inclusion absorbers for basic metal manufacturing?
**A**: Primary materials include calcium-aluminate based compounds for effective inclusion capture, fluoride-containing compounds to modify flux viscosity and reactivity, and reactive oxide blends designed to optimize steel purity during continuous casting processes.

### Q: Why are inclusion absorbers important for steel quality in continuous casting?
**A**: Inclusion absorbers are critical for removing harmful non-metallic particles that can cause defects, reduce strength, and impair surface quality in finished steel products, ensuring higher purity and better performance in downstream applications.
