good quality competitive price oxygen probe for Steel & Cast Iron Melting

Present in the molten steel in the number of oxygen, the quality of molten steel, ferroalloy and finished product rate of consumption has a key influence. With the exception of boiling steel, semi-killed steel expanding (and beyond boiling and aluminum killed steel deoxidation molten steel continuous casting steel production and refining technology is widely used, the urgent need for rapid, accurate and direct understanding of the oxygen content in molten steel, in order to control steelmaking operations, improve quality and reduce consumption.

Oxygen probe is to meet the above requirements of production design and manufacture a molten steel oxygen content and temperature of molten steel metallurgical sensing probe assay.

Application: it can be used for LF, RH, etc. refining station, measuring station steel oxygen activity and process oxygen activity measurement, be sure to include the amount of oxygen scavenger, shorten smelting time, help develop new varieties, improve the process to improve steel purity.

Main features: and scope of application from high-oxygen and hypoxic type two kinds. Suitable for high-oxygen converter, electric furnace, refining furnace of molten steel temperature and high oxygen content; hypoxic type is suitable for measuring the temperature and oxygen content of the molten steel in LF, RH, DH, tundish, etc., and can be quickly measured acid dissolved aluminum.

Principle: oxygen probe in a "solid dielectric constant oxygen concentration cell technology", which can be measured the temperature and oxygen content of the molten steel at the same time. Oxygen probe by the half-cell and thermocouples. The test principle is known in the oxygen partial pressure is a reference cell, and the other between the measured oxygen content of the molten steel, connected by oxygen ions of the solid electrolyte, an oxygen concentration cell constituted. By measuring the temperature and oxygen potential of the molten steel, which can calculate the amount of oxygen in the molten steel.
