# Industrial Specification: Integrated Hot Strip Rolling and Finishing System

## 1. Technical Definition
Coordinated production line for transforming steel slabs into finished hot-rolled coils

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa hydraulic pressure, 1000-1250°C slab temperature, 0.5-25 m/s rolling speed**. Failure boundary: **Hydraulic pressure &lt;0.65 MPa causes insufficient roll force, slab temperature &lt;950°C causes rolling fracture, rolling speed &gt;28 m/s causes strip instability**, Mechanism: **Yield strength-temperature relationship (Arrhenius equation), hydrodynamic lubrication breakdown (Reynolds number &gt;10^5), thermal stress exceeding yield point (σ_thermal &gt; σ_yield)**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| U | Heat Transfer Coeff | Engineering Constant |
| A | Area | Engineering Constant |
| \Delta T_{lm} | LMTD | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Work roll thermal crown exceeding 150 μm differential | 8 | Strip profile deviation &gt;40 μm from target | Roll bending force control system with 10 kN/m resolution and adaptive crown compensation algorithm |
| Looper tension control error &gt;15% of setpoint | 8 | Strip thickness variation exceeding ±50 μm | Multi-loop tension control with hydraulic servo valves (0.1 ms response) and mass flow compensation |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
