- Abstract
The control and optimization of radial gas distribution in a blast furnace are crucial in managing blast furnace melting. This study is based on long-term (more than 60 years) experience in developing and testing a device for the continuous automatic control of radial gas distribution using a non-cooled radial multipoint thermocouple installed permanently above the stockline level. Measuring the surface temperature of the last portion of the loaded charge and not the temperature of the gas released from the charge layer, we established the unreasonableness of indirect (radiating and acoustic pyrometry) methods for monitoring radial gas distribution on the blast furnace throat. To control the radial gas distribution, we conclude that it is necessary to use data on the temperature of gas released from the charge layer obtained by direct measurement.
