12mm Protection Tube Diameter Platinum/Rhodium Thermocouple For Molten Iron 300mm Probe Length for Temperature Environments

Product Description:

Knowledge is power in the fiercely competitive landscape of modern foundries and steel mills. Among the most crucial pieces of information is the precise temperature of your molten iron. This single data point determines the success of every subsequent operation—from inoculation and alloying to tapping and pouring. An incorrect reading can result in severe consequences: cold shuts, misruns, gas porosity, weakened mechanical properties, and ultimately, excessive scrap rates.

The Huarui Robust Immersion Thermocouple is specifically designed to be the reliable temperature monitor of your molten metal process. We recognize that measuring temperatures above 1300°C in a harsh, abrasive, and thermally stressful environment is one of the most challenging tasks in industrial sensing. Therefore, our HR-TC-MI Series is more than just a sensor; it is a sophisticated, disposable system created for a single purpose: providing speed, precision, and dependability when it is most crucial, protecting your product quality and financial results.

Features:

A Superior Thermocouple for Harsh Environments

A superior thermocouple is a synergy of advanced materials and precision engineering. Every component of the HR-TC-MI is optimized for the harsh reality of the foundry floor.

The Sensing Element: The Heart of Accuracy

Type S (Platinum-Rhodium) Excellence: For the most demanding applications and highest accuracy requirements, we offer Type S (Platinum/Platinum-10% Rhodium) elements. These provide exceptional stability and precision for critical iron and steel processing.

Robust Type B & R Options: For even higher temperature ranges found in steel production, Type B (Platinum-30% Rhodium/Platinum-6% Rhodium) elements are available, offering superior longevity and resistance to degradation.

Metallurgical Purity: Our noble metal wires are of the highest purity, ensuring a stable and consistent Electromotive Force (EMF) output, which is the foundation of a precise temperature reading.

The Protective Sheath: The First Line of Defense

The sheath is the component that bears the full brunt of the molten metal's chemical and thermal assault.

High-Zirconia Ceramic (ZrO₂): Our standard for excellence. Zirconia sheaths offer outstanding resistance to molten iron erosion and slag attack. They possess exceptional thermal shock resistance, surviving the rapid temperature change from room temperature to 1600°C+ in seconds without cracking.

Fused Quartz (SiO₂): A cost-effective alternative for certain iron applications, providing good thermal shock resistance and non-wettability against molten iron.

Alumina (Al₂O₃): For ultra-high temperatures and environments requiring extreme mechanical strength and chemical inertness.

Multi-Layer Protection: Key models feature a multi-layered construction, often with an inner insulator and an outer protective tube, to maximize safety and signal integrity.

The Paper Tube & Connecting Head: Seamless Integration and Safety

Steel-Wire Reinforced Paper Tube: The sturdy paper tube provides structural integrity for safe immersion. It is often reinforced with steel wires to prevent bending or breaking during handling. Its combustible nature is a safety feature, ensuring it burns away cleanly without contaminating the metal.

Standardized Quick-Connect Plug: The industrial-standard ceramic or plastic connector head ensures a foolproof, secure connection to your temperature display unit or automated temperature measurement system. This eliminates signal noise and connection failures.

The Moisten Agent: Ensuring a Clean Measurement

The tip of the thermocouple is often coated with a special moisten agent. This coating serves a vital function: it promotes immediate wetting of the sheath by the molten metal, preventing slag adhesion and ensuring a rapid thermal transfer for a faster, more representative reading.

Core Product Advantages: Why Huarui is the Uncompromising Choice

Blazing Fast Response Time: < 4 Seconds
Our thin-walled, optimally designed sheaths transfer heat with incredible speed, capturing the true temperature of the metal before the bath can cool or the thermocouple can degrade. This allows for quicker decisions and higher throughput.

Unwavering Measurement Accuracy: ±0.2%~0.5% of Reading
Precision-engineered sensing elements and high-quality materials ensure that the temperature you see is the temperature you have, giving you the confidence to make perfect metallurgical calls.

Exceptional Thermal & Mechanical Shock Resistance
The proprietary material composition and manufacturing process of our sheaths create a component that can withstand repeated, rapid immersion without failure, ensuring reliability across every heat.

Superior Slag & Erosion Resistance
The dense, non-porous microstructure of our ceramic sheaths minimizes erosion from the abrasive molten metal and resists penetration by corrosive slags, leading to a longer usable life and consistent performance.

Operational Safety & Ease of Use
From the easy-grip paper tube to the unambiguous quick-connect plug, every aspect is designed for operator safety, efficiency, and to minimize human error in high-stress environments.

Applications:

The HR-TC-MI Series plays a crucial role throughout the molten metal workflow. From furnace or ladle tapping to in-ladle treatment stations and pre-pour assessments in transfer ladles, it ensures that the metal is always at the optimal temperature for various processes.

During furnace or ladle tapping , this series helps determine the precise tapping temperature, guaranteeing that the metal is within the ideal range for treatment and pouring.

For in-ladle treatment stations , the HR-TC-MI Series is essential for monitoring temperature variations during inoculation and alloying, as these processes are highly sensitive to temperature changes.

In the transfer ladle , the series aids in conducting a pre-pour assessment to verify that the metal has not cooled below the necessary fluidity threshold before it enters the mold.

Lastly, in channel furnaces , specific models of the HR-TC-MI Series are designed for continuous temperature monitoring during longer-term immersion or frequent dipping, ensuring consistent performance.
