Basic Oxygen Furnace (BOF) Process Measurement and Control Solutions

Basic Oxygen Furnace (BOF) is another commonly used furnace in the steelmaking industry, which uses oxygen to decarbonize the molten iron and produce steel. Similar to electric arc furnaces, BOFs require precise control and measurement of various process parameters to ensure optimal performance and quality. Some of the key process measurement and control solutions used in BOFs include:

Temperature Measurement:

Temperature measurement is critical in a BOF to ensure optimal steelmaking performance and quality. The temperature of the molten steel and slag must be accurately measured and controlled throughout the process. Various temperature measurement devices such as our Canadian manufactured Thermocouples, Ametek Land Pyrometers and Infrared Sensors are used for this purpose.

Process Monitoring:

Real-time monitoring of various furnace parameters such as temperature, oxygen input, and gas flow rate is essential to ensure optimal performance and prevent any abnormalities or malfunctions. Various Honeywell Analytical Instruments & Smart sensors and Honeywell Process & Temperature Controllers are used to continuously monitor the process and alert operators in case of any deviations from the desired parameters.

Oxygen Control:

The oxygen input to the furnace must be carefully controlled to ensure optimal decarbonization and steel quality. Honeywell Analytical Instruments & Smart Sensors are used to regulate the oxygen input to the furnace based on various parameters such as temperature, carbon content, and steel chemistry.

Gas Analysis:

The composition of the gas used in the BOF can have a significant impact on the quality of the final product. Crowcon Gas Analysis Systems are used to measure the composition of the furnace atmosphere and adjust the gas flow rate to maintain the desired levels of oxygen, nitrogen, and other gases.
