# Industrial Specification: Molten Metal Temperature Measurement System

## 1. Technical Definition
Automated system for continuous temperature monitoring of molten metals during processing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **700-1800°C**. Failure boundary: **Thermocouple sheath material melting point (e.g., Inconel 600 at 1371°C, Molybdenum at 2623°C)**, Mechanism: **Thermal degradation of thermocouple junction materials (Seebeck coefficient drift) and sheath oxidation/embrittlement above 1200°C in oxidizing atmospheres**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$
