Product Description

The molten steel online hydrogen determination system provides you with the method of online hydrogen measurement at the steelmaking site. It is fast and accurate. It makes it possible to directly control the hydrogen content in the steelmaking process.
The hydrogen probe is a disposable element. Inside it is equipped with a blowing quartz tube, a vent plug, a filter chamber, and a connecting piece. It is mainly composed of the high-temperature resistant quartz tube, high-strength aluminum alloy connector, corresponding filter material, high-temperature resistant paper tube, and splash-proof ceramic fiber. The whole measurement cycle can be completed within 30~60s.

Working Principle
Immersion probes can measure the hydrogen content of molten steel online. Nitrogen, as a carrier gas, enters the molten steel through the probe and absorbs the hydrogen in the molten steel until the hydrogen content in the carrier gas and the hydrogen content in the molten steel reach equilibrium.

Work Method
Nitrogen, as the carrier gas, is pushed through the gas line by the pump in the loop. The blowing pipe on the measuring gun and the probe enter the molten steel and form bubbles. The nitrogen bubbles absorb the hydrogen in the molten steel and return to the pneumatic cabinet through the vent plug of the inner hood of the probe, and the carrier gas circulates in the loop for many times. Finally, the hydrogen content in the molten steel and the hydrogen partial pressure in the carrier gas reach equilibrium.
