Influence of Ore to Coke Ratio Distribution on Descending and Melting Behavior of Burden in the Blast Furnace
Article
  • Jan 1991
The influence of ore/coke distribution on the descending and melting behaviors of burden was analyzed by using a three-dimensional semicircular warm model of the blast furnace under conditions set as similar as possible to the physical phenomena in the furnace. If the ore/coke in wall region is locally increased, the descending velocity increases and the gas flow velocity decreases in that region. An increase of +0.1 in the heat-flow ratio in the wall region of bosh results in a decrease of about 5°C (80°C in the value converted into that of the actual blast furnace based on the Stanton number) in the wall temperature of bosh. At the all coke operation, as the wall temperature in the lower part of the furnace tends to decrease, the ore/coke near the wall should be preferably decreased by the charging of ore closer to the furnace center. At the high-rate coal injection operation, as the melting capacity near the wall is large, the ore/coke in the wall region should be preferably increased and the ore/coke in the center region should be preferably decreased by the charging of ore farther from the furnace center.

Development of a Mathematical Model to Estimate Burden Distribution in Bell-less Type Charging for Blast Furnace
Article
  • Jan 1987
Many types of burden distributions can be produced by bell-less type charging equipment tor BF. However, the change in configuration of burden layer occurs in a furnace top. Therefore, the accumulated state of burden has been investigated by using an experimental apparatus built on a scale of one third of Muroran No. 1 blast furnace, and a mathematical model to estimate the burden distribution has been developed. 1) Materials charged at each turn of rotating chute form the burden layer with convex surface on the landing area. 2) Ore layer formed after each turn of rotating chute shows different configuration before and after occurrence of the coke layer collapse. 3) Change in particle size distribution depends on the charging conditions and gas flow. A regression equation expressing these relations has been obtained. 4) On the basis of the findings, a mathematical model in which the in-furnace parameters affecting burden distribution are taken into consideration has been developed. This model has a feature in regard to introduction of the idea that the imaginary unit volume is given by dividing one dump volume of materials into many pieces and burden distribution is constructed by accumulation of the unit volume. By applying the mathematical model to Muroran No. 1 blast furnace, the suitable furnace operation has been obtained.
Application of simulation model for burden distribution to actual operations.
Article
  • Jan 1984
A simulation model for the burden distribution at blast furnace top was used for the quantitative evaluation of the effects of various charging conditions on the burden distribution and was applied to the actual operations at Kokura #2BF in cases of the control of hot spot occurrence at lower shaft and the control of furnace wall 'activeness'.Among three charging conditions, that is, coke base, charged O/C, and stock level, coke base has the most significant effect on the burden distribution. The decrease in charged O/C at furnace center was accelerated by the mixed layer formation during ore dumping in cases of the increase in coke base and charged O/C. On the other hand, the rise of stock level resulted in the increase in charged O/C at furnace center, which differs from the previous knowledge.For the restraint of hot spot occurrence, both suitable selection of movable armor notch based on the model computation and the mortar injection are important. To enhance wall 'activeness' the movable armor operation was successfully performed on the basis of the model computation. Through these applications of the model to actual operations, the effectiveness and the usefulness of the model was confirmed.
Development of Monitoring System for Lumpy and Cohesive Zones in the Blast Furnace
Article
  • Oct 1982
At No. 2 blast furnace of Sakai Works, effort is being made to develop and practically apply new types of sensors (magnetometer, and gas flow meter) and probes (shaft diameter probe, shaft wall probe, etc.) for accurate measurement of gas flow distribution and burden behavior in the lumpy zone. Mathematical models for estimation of the state of lumpy zone and the outer profile of cohesive zone in the furnace have been developed. The cohesive zone model is composed of simultaneous ordinary differential equations including heat transfer equations and material balance equations, and the Runge-Kutta-Gill method is employed to obtain numerical solution for this model. By using the information from these new probes and models several new findings have been obtained.

  • Oct 1982
Gas distribution control has remarkably contributed to the stabilization of blast furnace operation and the improvement in efficiency. In Kawasaki Steel Corporation sensors for gas distribution control and their quantification have been developed.In this report the following items are described.1) Survey of the sensors for gas distribution control.2) Quantification of gas temperature distribution and gas component distribution by use of discriminant function analysis.3) Three types of burden profile meter newly developed by Kawasaki Steel Corporation.4) Their correspondence to actual blast furnace operation both macroscopically and microscopically.Above mentioned sensors were used effectively in actual blast furnace operation. Efficient and stable operation of blast furnaces have been kept in Kawasaki Steel Corporation.
Development of a simulation model for burden distribution at blast furnace top.
Article
  • Jan 1983
A simulation model for the burden distribution at a blast furnace top was developed. In addition to the static deposit angle, the following factors which have strong effect on the burden distribution were considered in the model.1) Mixed layer formation in the furnace center during ore dumping2) Decrease of burden deposit angle by gas flow3) Change of burden deposit angle by the velocity distribution of burden descent in the radial directionFor the quantitative evaluation of these effects the mixed layer measurement by the use of a magnetometer during furnace fillings and the measurement of the change in deposit angle with gas flow by the use of a 1/2 scale cold model were performed. As a result, the increase in coke layer thickness in the furnace center (ΔLc) is expressed by the following experimental equation through the use of “formation energy of mixed layer” (EM). ΔLc=3.49×10-4×EM-136Among factors mentioned above, the mixed layer formation was confirmed by the model to have the most significant effect on the burden distribution.
