# Industrial Specification: Slag Crushing System

## 1. Technical Definition
A mechanical system designed to crush and reduce the size of slag produced during hot metal desulfurization for subsequent processing or disposal.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa hydraulic pressure, 15-45 RPM crushing speed**. Failure boundary: **Hydraulic pressure exceeding 3.2 MPa causes cylinder seal rupture; crushing speed exceeding 55 RPM induces bearing resonance at 185 Hz**, Mechanism: **Seal failure due to elastomer extrusion at 3.2 MPa (Young's modulus 7.5 MPa); bearing resonance at 55 RPM matches natural frequency of 185 Hz causing fatigue fracture**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| m | Eccentric Mass | Engineering Constant |
| r | Radius | Engineering Constant |
| \omega | Angular Frequency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Slag temperature exceeding 650°C | 8 | Thermal expansion mismatch between manganese steel hammers (α=13×10⁻⁶/°C) and carbon steel shaft (α=11×10⁻⁶/°C) | Install infrared temperature sensors with 550°C interlock and use Inconel 718 thermal barrier coatings (CTE 12.6×10⁻⁶/°C) |
| Silica content &gt;25% in slag composition | 8 | Abrasive wear rate exceeding 0.15 mm/hour on crusher liners (Mohs hardness 7.5 vs liner hardness 450 HB) | Implement XRF composition analyzer with 20% silica cutoff and install tungsten carbide overlays (hardness 1500 HV) |
