Fixed hydrogen probe

Product Introduction

The online hydrogen fixing system can meet the needs of rapid determination of hydrogen content during vacuum refining, continuous casting and other processes. The steel water-fixed hydrogen probe has become a necessary component for testing the hydrogen content when smelting high-quality steel and special steel types. This product provides effective data support for smelting control, improving steel quality, and ensuring product qualification rate.

The Steelmaking Hydrogen Probe is a specialized high-temperature sensor designed to measure hydrogen activity in molten steel during secondary refining processes. Accurate hydrogen monitoring is essential for producing high-quality steel, particularly in applications that demand low hydrogen content to prevent defects such as flaking, porosity, and cracking.
