In a basic oxygen furnace, carbon-rich molten iron (pig iron) is converted to steel by blowing oxygen through a top-mounted lance at supersonic speeds into the molten iron. This reduces the carbon content of the alloy and converts it into low carbon steel.<\/p>\n

Due to the high competitiveness of the industry, it is essential to achieve process control to ensure optimum efficiency, maximizing product quality and process safety and minimizing energy consumption.<\/p>\n<\/p>\n

Process<\/h3>\n

The oxidation of carbon during the oxygen conversion process is of vital importance to reduce the level of carbon and other impurities.<\/p>\n

When oxygen is blown over the molten metal, as a result of the reaction, the temperature increases and a large amount of CO and CO2 gases are produced, causing agitation of the metal and slag.<\/p>\n

Here the slag layer plays an important role in binding carbon and other impurities and helps to remove hydrogen, nitrogen and some of the non-metallic inclusions from the metal.<\/p>\n

Therefore, monitoring CO concentration is a key indicator to determine when the melting process and decarbonization has reached its end point.
Measuring the O2 level helps the operator control the flow of oxygen to the melt.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
