Abstract
Blast furnace visualization and simulation technology are used for monitoring the BF burden charging process and operation status to guide blast furnace operation. Laser grid and laser scanning are used for burden filling study before starting a newly built or relined furnace. Falling burden trajectories and the configuration of the burden surface can be obtained and used as the input of a simulation model. Laser detector is used for online observation and measurement of burden profile during furnace operation. Simulation model of burden distribution is used to simulate furnace charging and burden descending process. Thickness distribution of burden layers and O/C curves can be calculated from the model. BF top video camera and thermal camera are applied to on line observe furnace burden surface situation and burden charge equipment. It can also provide operators adequate information including furnace top gas distribution and detect real time irregular phenomena inside the furnace. Tuyere camera is used to monitor the working status and PCI situation in front of every tuyere with images and diagrams displayed in the control room. At present, blast furnace visualization and simulation technology is applied on more than 450 BFs at the mainland China and Taiwan. Besides, more than 20 blast furnaces abroad are also using this technology.
