Oxygen Probe
1. OutlineOxygen,Website:http://www.cfsampler.com, which exists in molten steel, plays a decisive role in the quality of molten steel, yield and consumption of ferroalloys. With the continuous expansion of the production of boiling, semi-killed and aluminium deoxidized continuous casting steels and the wide application of molten steel refining technology, it is urgent to know the oxygen content in molten steel quickly, accurately and directly in order to control steelmaking operation, improve quality and reduce consumption. Solid electrolyte concentration difference oxygen determination technology is developed to meet these requirements.2. PrincipleSolid electrolyte oxygen concentration determination consists of two half cells, one is a reference cell with known oxygen partial pressure, and the other is molten steel with oxygen content to be measured. Two half-batteries are connected with oxygen ion solid electrolyte to form an oxygen concentration cell. The oxygen content can be determined by measuring the oxygen potential and temperature.?3.

UsageA. Strictly check the probe, test the grab and instrumentation system to ensure integrity.B. The oxygen probe is mounted on the test gun. The instrument pointer (digital display) returns to zero to indicate good conduction and direction measurement.C. When measuring, the probe should not stay in molten steel for more than 10 seconds, otherwise it is easy to burn the test gun.5.
