# Industrial Specification: Collector Nozzle / Well Nozzle

## 1. Technical Definition
A precision nozzle component within a flow control device that collects and directs molten metal from a tundish into the mold during continuous casting.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa (5-25 bar) at 1550-1600°C**. Failure boundary: **Thermal stress exceeds 350 MPa yield strength of zirconia-based refractory at 1650°C**, Mechanism: **Thermal fatigue from cyclic temperature gradients exceeding 200°C/mm during casting sequence transitions, combined with erosion from alumina inclusions at velocities &gt;1.2 m/s**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

- **Caution**: 

### Q: What materials are used in collector nozzles for continuous casting?
**A**: Collector nozzles are typically manufactured from high-performance refractory materials including alumina-graphite, zirconia-graphite, and fused silica to withstand extreme temperatures and corrosive molten metal environments.

### Q: How does a collector nozzle function in continuous casting?
**A**: The collector nozzle precisely directs molten metal from the tundish into the mold during continuous casting, ensuring controlled flow rates and preventing turbulence that could cause defects in the final metal product.

### Q: What are the key components of a collector nozzle assembly?
**A**: The main components include the nozzle body, which controls metal flow, and the seating surface, which ensures a secure, leak-proof connection between the tundish and the casting system.
