Made in China Made in China High Quality Immersion Molten Steel Sampler for Steel Mills Made in China Made in China High Quality Immersion Molten Steel Sampler for Steel Mills Made in China High Quality Immersion Molten Steel Sampler for SteelMills To meet the above production requirement, oxygen probe is designedas a kind of metallurgy detection probe of measuring the oxygencontent in molten steel and the temperature of molten steel. 1.3.1 Application: Used for primary melting furnace,LF and RHfurnaces, oxygen probes measure oxygen activity of the molten steelin the treating process, which can guarantee the deoxidizeraddition, shorten the refining time, help develop new varieties,improve technology, and promote steel purity. 1.3.2 Main features and range of application: Oxygen probe has twotypes: high oxygen probe and low oxygen probe. The former is usedto measure the temperature and high oxygen content of molten steelin converter, electric furnace, refining furnace. The later is usedto measure the temperature and low oxygen content of molten steelin LF, RH, DH, tundish, etc. and also quickly measure acid solublealuminum. 1.3.3 Principle: "Solid dielectric concentration celloxygen-content test technology" is applied in oxygen probe, whichallows to measure the temperature and oxygen content of moltensteel at the same time. Oxygen probe consists of half-cell andthermocouple. Solid dielectric concentration cell oxygen-contenttest is composed of two half-cells. wherein one is known referencecell of known oxygen partial pressure, and the other is the moltensteel. The two half-cells are connected by oxygen ions solidelectrolyte, forming an oxygen concentration cell. Oxygen contentcan be calculated from the measured oxygen potential andtemperature of the molten steel. 1.3.4 Features: 1) The oxygen activity of the molten steel can bemeasured directly and rapidly, which is helpful to determine theamount of the deoxidizing agent, and improve the operation of thedeoxidation. 2) The oxygen probe is easy to operate. Measurement results can beobtained just 5-10s after inserting it into the molten steel. 1.3.5 Main technical indexes: 1) High oxygen probe 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 usuallyabove 98%, but it is related to operations of the workers; ifmisused, measurement efficiency will be reduced. Note: If oxygen activity in molten steel is above 50ppm, highoxygen probe is suggested. 2) Low oxygen probe 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 usuallyabove 98%, but it is related to operations of the workers; ifmisused, measurement efficiency will be reduced. Note: If oxygen activity in molten steel is between 1ppm and 50ppm,low oxygen probe is suggested. 3) Ultralow oxygen probe 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 usuallyabove 98%, but it is related to operations of the workers; ifmisused, measurement efficiency will be reduced. Note: If oxygen activity in molten steel is between 1ppm and 5ppm,low oxygen probe is suggested. If oxygen activity is between 1ppmand 5ppm, ultra low oxygen probe is more accurate than low oxygenprobe. Oxygen sensor is a kind of metallurgy detection probe which isdesigned to measure the oxygen content and temperature of themolten steel fast, accurately and directly. 1. Application: Used for primary melting furnace,LF and RH furnaces and so on, oxygen probes measure oxygen activityof the molten steel and the oxygen activity of the molten steel inthe treating process, which can guarantee the deoxidizer addition,shorten the refining time, help to develop new varieties, improvetechnology, and promote steel purity. 2. Main features and range of application: Oxygen sensor has three types: 1) Oxygen sensor for high ppm 2) Oxygen sensor for low ppm . 3) Oxygen sensor for ultra-low ppm. The first one is used to measure the temperature and high oxygencontent of molten steel in converter, electric furnace, refiningfurnace. The second one is used to measure the temperature and lowoxygen content of molten steel in LF, RH, DH, tundish, etc. andalso quickly measure acid soluble aluminum. The third one issuitable for the steel smelting process which require the ultra-lowoxygen content. 3. Principle: "Solid dielectric concentration cell oxygen-content testtechnology" is applied in oxygen sensor, which allows to measurethe temperature and oxygen content of molten steel at the sametime. Oxygen sensor consists of oxygen cell and thermocouple.Oxygen content can be calculated from the measured oxygen potentialand temperature of the molten steel. 4. Features: 1) The oxygen activity of the molten steel can be measured directlyand rapidly, which is helpful to determine the amount of thedeoxidizing agent, and improve the operation of the deoxidation. 2) The oxygen sensor is easy to operate. Measurement results can beobtained just 5-10s after inserting it into the molten steel. 5.
