摘要： The reducing power of gases liberated at the top of the charge of an industrial furnace is determined by a method wherein the energy radiated from the charge in the range, for example between 1 and 6 microns, covering the radiant energy emitted by the compounds CO.sub.2, CO, H.sub.2, and CH.sub.4 is continuously measured in a multiplicity of detection points distributed over the entire upper surface of the charge and outputs are formed corresponding to the energy radiated at each of the points. An energy image of the energy radiated at the points in the range is formed from the outputs. This energy image is converted into respective specific images for the compounds by isolating from the energy image for each detection point the radiant energy emitted by the compounds. The concentration of each of the compounds at each of the points is calculated from the intensity of the respective specific image. Finally the reducing power at each of the detection points is derived from the respective concentrations of the compounds thereat.

摘要： A method of monitoring the wear of refractor walls of a blast furnace wherein temperature is sensed at different points across the thickness of the furnace walls and various electric representations of the internal phenomena of the blast furnace are derived as trigger signals. Analysis is carried out as to the correlation between the trigger signals and variations in the temperatures at the furnace walls in terms of the time delay, thus predicting the present status of the wear of the furnace walls. A temperature probe assembly is also disclosed which is useful in sensing the temperature distribution of the refractory walls. The temperature probe assembly includes a plurality of parallel sheath type thermocouples or thermometers.

摘要： The present invention discloses a blast-furnace operation method which comprises selecting three factors, i.e. the oxygen volume in blast, the ore/coke and the reducibility of the burden materials as control factors from among these which participate in the variation of heat input and heat output of blast furnace, plotting values of these three factors obtained from the practical operation of efficient blast furnaces on a graph consisting of three parallel axes indicating the three factors, evaluating the conditions of furnace heat with reference to a balanced state of the three plotted factors and adjusting one or more of the three factors in the furnace so all will lie within a suitable range thereby balancing the furnace heat.

摘要： In controlling a slab reheat furnace, the average temperature of each slab in a zone, is predicted as a function of the radiation heat source temperature in the zone, and the thermal properties, dimensions, location, velocity, and past thermal history of the slabs. The predicted slab temperatures are compared with a range of desired slab temperatures and the slab requiring the greatest time to be heated to its desired temperature is identified. The furnace is controlled in such a manner that the identified slab will be heated to the desired temperature. Slabs likely to be overheated are identified and, if a predetermined temperature limit is to be exceeded, the furnace is controlled to prevent further heating of the slabs. Gas temperatures throughout the zone are predicted based upon only one sensed temperature in the zone.
