# Industrial Specification: Rotating Distribution Chute

## 1. Technical Definition
A rotating chute mechanism that evenly distributes raw materials into a blast furnace.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa hydraulic pressure, 0.1-0.8 rpm rotation speed, 800-1200°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 3.2 MPa causes seal extrusion, rotation speed below 0.05 rpm leads to material bridging, temperature above 1350°C initiates creep deformation**, Mechanism: **Seal failure occurs via extrusion when hydraulic pressure exceeds 3.2 MPa (based on HNBR seal material yield strength of 15 MPa with 5:1 safety factor). Material bridging follows Janssen's equation when rotation speed drops below critical shear rate. Creep deformation initiates at 0.5% Larson-Miller parameter of 1350°C·(20+log(t)) where t=1000 hours**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
