# Industrial Specification: Electroslag Remelting Furnace

## 1. Technical Definition
Secondary refining furnace for high-quality metal ingots

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 MPa electrode pressure, 40-80 VDC, 10-50 kA current**. Failure boundary: **Electrode pressure exceeds 2.5 MPa causing slag pool instability, or current density surpasses 15 A/cm² leading to electrode erosion**, Mechanism: **Electromagnetic pinch effect instability at current densities &gt;15 A/cm² disrupts slag-metal interface, causing non-uniform solidification and ingot defects**.

### 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.
