Product Description

 Product Name:immersion Disposable sampling steel-making mill usage compound Oxygen Probe for molten steel


1.Product Introduction

The amount of oxygen existing in molten steel has a critical influence on the quality of steel, the yield of finished steel and the consumption of ferroalloy. With the boiling steel and SEMIKILLED steel (static steel and aluminum deoxidation of continuous casting steel is widely used in boiling outside) the continuous expansion of production and refining technology, the urgent need for rapid and accurate and direct understanding of oxygen content in molten steel, so as to control the steelmaking operation, improving quality and reducing consumption.
The oxygen probe is a metallurgical testing probe designed to meet the above requirements and to measure the oxygen content in molten steel and the temperature of molten steel.


1, application: can be used for LF and RH refining station, measuring oxygen activity of oxygen activity and process of molten steel in the measuring station, ensure the amount of deoxidizer, shorten the melting time, help the development of new varieties, improve the process to improve the purity of molten steel.
2, scope of application:
There are two types: high oxygen type and low oxygen type. High oxygen determination in converter, electric furnace, refining furnace temperature and high oxygen content; hypoxia model was applied to the determination of RH, DH, LF furnace, tundish steel temperature and oxygen content, and can realize the rapid measurement of acid soluble aluminium.



In the oxygen probe, the "solid dielectric concentration cell oxygen determination technique" is used to determine the temperature and oxygen content of the molten steel simultaneously. The oxygen determination probe consists of a half cell and a Thermocouple. The test principle is that an oxygen concentration cell is formed by connecting an oxygen ion solid electrolyte with a reference cell whose oxygen partial pressure is known, and the other is a liquid steel whose oxygen content is to be measured. By measuring the temperature and oxygen potential of the molten steel, the oxygen content in the tapping water can be calculated.
4, characteristics:
1) direct and rapid measurement of oxygen activity in molten steel is helpful to determine the amount of deoxidizer added and the deoxidation operation during modification;
2) the equipment is simple and easy to operate. The oxygen probe is directly inserted into the steel water, and the measurement result can be obtained only with 5-10S.


2,Product Specifications

1, measuring range
Range of temperature measurement: 1200 ~ 1750 DEG C
Oxygen potential: -200 to ~+350mV
Oxygen activity: 1 ~ 1000ppm
2, measurement accuracy
Oxygen battery reproducibility: Steel LOX activity is not less than 20ppm, the error is about 10% ppm
When the liquid oxygen activity of the steel is less than 20ppm, the error is + 1.5ppm
Thermocouple accuracy: 1554 DEG C, + 5
3, response time
Oxygen cell 6 ~ 8s
Thermocouple 2 ~ 5S
The whole process is from 10 to 12s
4, high success rate of oxygen is not less than 95%; hypoxia type = 95%
Model and technical characteristics:
Model: KOSZ-1300
The relation between temperature and oxygen activity is as shown in the formula
Loga (0) =1.36+0.0059 = [E+0.54 (t-1550) +0.0002 • E • (t-1550)]
The E unit is MV, and the T unit is centigrade
The accuracy of Thermocouple Wire at + 1554 is + [1+ (t-1100) *0.003] DEG C
Oxygen cell [(Cr+Cr2O3/ZrO2 (MgO))] repeatability test at ambient temperature at 1580 C, the standard deviation is 1.5-2mv
The response curves of temperature and oxygen signals showed stable plateau and short response time, with immersion time of 6-8 seconds
Product specification and packing:
