Product Description

 Product Name:liquid oxygen sampling steel-making mill usage compound probe for molten steel


1.Product Introduction


Used for primary melting furnace,LF and RH furnaces and so on, oxygen probes measure oxygen activity of the molten steel and the oxygen activity of the molten steel in the treating process, which can guarantee the deoxidizer addition, shorten the refining time, help to develop new varieties, improve technology, and promote steel purity.



1) The oxygen activity of the molten steel can be measured directly and rapidly, which is helpful to determine the amount of the deoxidizing agent, and improve the operation of the deoxidation.

2) The oxygen sensor is easy to operate. Measurement results can be obtained just 8-10s after inserting it into the molten steel.


2,Product Specifications

Main technical indexes:

1) Oxygen sensor for high ppm

Working condition: 1400℃-1760℃

Measuring range: 50ppm~1000ppm

Measurement resolution: 0.1mv

Measurement accuracy: 0~5mv

Oxygen potential: -300mv~+300mv

Response time: 8s-10s

Measurement efficiency: 98%

Measurement efficiency is usually above 98%, but it is related to operations by the workers; if misused, measurement efficiency will be reduced. 


Note: If oxygen activity in molten steel is above 50ppm, oxygen sensor for high ppm  is suggested. 


2) Oxygen sensor for low ppm 

Working condition: 1500℃-1760℃

Measuring range: 1ppm~1000ppm

Measurement resolution: 0.1mv

Measurement accuracy: 0~3mv

Oxygen potential: -300mv~+300mv

Response time: 8s-10s

Measurement efficiency: 98%

Measurement efficiency is usually above 98%, but it is related to operations by the workers; if misused, measurement efficiency will be reduced. 


Note: If oxygen activity in molten steel is between 1ppm and 50ppm, oxygen sensor for low ppm is suggested.


3) Oxygen sensor for ultra-low ppm

Working condition: 1500℃-1760℃

Measuring range: 1ppm~1000ppm

Measurement resolution: 0.1mv

Measurement accuracy: 0~1mv

Oxygen potential: -300mv~+300mv

Response time: 8s-10s

Measurement efficiency: 98%

Measurement efficiency is usually above 98%, but it is related to the operations by the workers; if misused, measurement efficiency will be reduced.


Note: If oxygen activity in molten steel is between 1ppm and 5ppm, oxygen sensor for ultra-low ppm is suggested. If oxygen activity is between 1ppm and 5ppm, oxygen sensor for ultra-low ppm is more accurate than oxygen sensor for low ppm.
