摘要： A blast furnace slag level estimation method and blast furnace slag level estimation apparatus can estimate the liquid level of slag to a high degree of accuracy. An operation guidance method, method of producing hot metal, and operation guidance apparatus also provide guidance for the operation of a blast furnace based on a highly accurately estimated liquid level of slag. The blast furnace slag level estimation method includes a step (S2) of calculating a liquid level of melt containing slag for each region in a plurality of regions separated by a low permeability zone, using a physical model that takes at least one of hot metal tapping rate, slag tapping rate, hot metal production rate, and slag production rate as an input and that is based on a mass balance assuming existence of the low permeability zone with poor permeation of slag at a bottom of a furnace.

摘要： A high temperature dry block temperature calibrator relates to the technical field of temperature calibration. The high temperature dry block temperature calibrator includes a high temperature furnace, a control board module, a system board module, a measuring board module, a lower support, and a housing. The high temperature furnace and the control board module are mounted on the lower support. The system board module and the measuring board module are mounted on the front side surface of the housing. The housing is clipped to the periphery of the lower support and the high temperature furnace and the control board module are accommodated in the housing. The modules are independent of each other and can be removed separately, thereby facilitating maintenance and replacement. The high temperature dry block temperature calibrator can be used for calibrating the temperature of a high temperature element to be measured.
