China supply high quality hydrogen probe with competitive price

System introduction

It is well known that hydrogen content in molten steel can directly affect steel quality. If hydrogen content in steel exceeds solubility value in solid steel, hydrogen will not solidify, and also cause perforation and multi-hole. Parts per million of hydrogen dissolving in steel will result in capillary crack, hydrogen embrittlement, hydrogen blistering and bad stretching and molding effect, which is more obvious especially in large-scale iron and steel casting, steel ingot and slab.

It is very important to measure hydrogen content in steelmaking process. The operator can directly and quickly measure soluble hydrogen in short time in virtue of hydrogen measurement instrument, lance and hydrogen probe (manual or machine operation). Hydrogen in molten steel is soluble, so hydrogen measurement system is aimed to measure total hydrogen content in molten steel.

Hydrogen measurement system of our company can accurately measure hydrogen content in molten steel. The principle is that nitrogen, the carrier gas, circulates between molten steel and pneumatic unit to collect hydrogen in molten steel. During measurement, soluble hydrogen will enter into nitrogen carrier gas bubble and therefore equilibrium can be reached between bubble and molten steel. The results will be displayed on the panel.

5.2 Usage

1. Preparation: first ensure correct connection among the instrument, lance and pneumatic cabinet and then start up according to the following steps:

Switch on the touch screen panel and pneumatic cabinet of the control room, feed carrier gas into the pneumatic cabinet and fix TCD (Thermal Conductivity Detector); before measurement, power of the touch screen panel and pneumatic cabinet of the control room must be on for at least 1 hour.

The steps are as follows:

1) Select measuring point.

2) Set solution temperature according to purpose.

3) Select check box of iron alloy.

4) Required values are input by the special key to prevent K/f factor from automatically switching to ON.

5) Have the vacuum test (vacuum pressure test in automatic mode)

6) Have the pressure test (vacuum pressure test in automatic mode)

7) Have the self test

If necessary:

8) Have known certified gas calibration check test

9) If necessary, recalibrate known certified gas.

If operations are without errors according to the above steps, preparations of hydrogen measurement system is ready.

2. Measurements:

(1) Instructions of the probe

1)Install the Probe firmly on the lance holder.

2) Immerse only through liquid steel or fluid slag.

3) Avoid immerse the probe into crusting slag.

4) Immerse the probe about 300mm dip

5) Do not immerse the probe above the non splash sleeve

6) Immerse probe far from nitrogen or argon bubbling or any other stirring gas

7) Immerse the probe as vertical as possible , NO > than 20 degrees from vertical

8) During measurement keep the probe in steady position. Do not move it right or left or up and down
