Monitoring the wear of the refractory lining in the blast-furnace hearth

The Razgar Gorna computer program is developed for calculating two-dimensional temperature fields in any vertical and horizontal cross section of the blast-furnace hearth. In the calculations, the heat-conduction equations are solved by means of readings from many temperature sensors (up to 1000, depending on the volume) installed within the furnace lining between the refractory modules. Continuous temperature monitoring at each point permits the determination of the remaining lining thickness and prediction of the onset of lining wear, as necessary. A mathematical model is employed in continuous temperature monitoring of the lining. The database of the Razgar Gorna program relies on the collection, analysis, and transmission of information from the temperature or heat-flux sensors. The program is in use at blast furnaces in Chinese steelworks at Jinan (two furnaces), Jiyuan, and Liuzhou. © 2013 Allerton Press, Inc

PROBABILITY DISTRIBUTION OVER THE SET OF CLASSES IN ARABIC DIALECT CLASSIFICATION TASK

Subject of Research.We propose an approach for solving machine learning classification problem that uses the information about the probability distribution on the training data class label set. The algorithm is illustrated on a complex natural language processing task - classification of Arabic dialects. Method. Each object in the training set is associated with a probability distribution over the class label set instead of a particular class label. The proposed approach solves the classification problem taking into account the probability distribution over the class label set to improve the quality of the built classifier. Main Results. The suggested approach is illustrated on the automatic Arabic dialects classification example. Mined from the Twitter social network, the analyzed data contain word-marks and belong to the following six Arabic dialects: Saudi, Levantine, Algerian, Egyptian, Iraq, Jordan, and to the modern standard Arabic (MSA). The paper results demonstrate an increase of the quality of the built classifier achieved by taking into account probability distributions over the set of classes. Experiments carried out show that even relatively naive accounting of the probability distributions improves the precision of the classifier from 44% to 67%. Practical Relevance. Our approach and corresponding algorithm could be effectively used in situations when a manual annotation process performed by experts is connected with significant financial and time resources, but it is possible to create a system of heuristic rules. The implementation of the proposed algorithm enables to decrease significantly the data preparation expenses without substantial losses in the precision of the classification

Monitoring System of Firebrick Lining Erosion of Blast Furnace Hearth

It is possible to increase the efficiency of the computer-based system of diagnostics of the elements state of the firebrick lining by means of use in their structure of the module, in real time revealing the structural changes of non-stationary controlled signals These changes as a rule testify the occurred deviations in the technical condition of the controlled object The received information about the revealed structural features in analyzed signals it is expedient to use for forecasting of further dynamics of controlled parameters The mathematical description and the computer program Hearth Erosion of calculation the two-dimensional temperature fields in any vertical and horizontal section of the blast furnace hearth are developed Calculation is carry out the decision of the equations of heat conductivity with use of indications of the big number of sensing transducers of temperature (to 1000), built in the furnaces firebrick lining between the firebrick blocks The continuous control of the temperature change in each point allows to define the remained thickness the firebrick lining and to warn, in case of need, the furnace personnel about the beginning of the firebrick lining erosion The continuous control of change of temperature in the firebrick lining is made on the basis of mathematical model The system of collecting, processing and transfer information from sensing transducers of temperature or thermal streams in a program database Hearth Erosion is used Programs are installed on blast furnaces of Chinese National Republic: Jinan, Jiyuan and Liuzhou Iron and Steel Works together with Russian- Chinese company SKKONT Copyright © 2013 IFAC.Work is carried out with supp ort and direct participation of Russian firm SKKONT (Limited liability co mpany “Research-and-production e nterprise "Northern c ompany of the completing equipment and new technologies ”)
