Tata Steel (India)
2012-2022
The coke reactivity index and strength after reaction are critical parameters for the efficient operation of a blast furnace. Therefore, maintaining desired qualities produced as per coal blend chemistry oven battery is essential. However, (CRI) (CSR) vary from laboratory to even though they have same determination methodology. In present investigation, unique sample holder test has been developed. method by Nippon Steel Corporation (NSC) compared with newly developed method. correlation...
The productivity and coke quality of a nonrecovery oven depends on coal blend, operating parameters, heating rate. A numerical methodology has been proposed for predicting temperatures the intermediate points with help measured temperature in oven. model was validated an actual profile five industrial ovens. developed can predict given set conditions. rate under normal operation found to be range 0.64–1.17°C/min. effect variation inside also correlated productivity.
Data mining technique has been used to develop the coke quality prediction model for stamp charge making. The developed is being optimize strength after reaction based on its coal blend properties and operating parameters. study shows actual plant CSR predicted of same were much closer proximity. Actual data have developing validation model. was successfully produce superior from oven batteries without damaging health.
Maximization of non-coking coal in blend is eloquent interest among researchers coke making throughout the world. To maximize coals with scarce and expensive coking an essential practice iron steel industry. The fundamental aspect blending theory low value to produce good quality metallurgical non-recovery process was investigated this study by using composite potential technique. implementation technique has yielded use up 25% pulverized injection, 20% raw petroleum as a component blend....
Inertinite, a maceral group, which remains inert or partly fuses during the carbonization process, plays vital role in coke making. During carbonization, vitrinite softens and resolidifies to form porous mosaic texture loses its original identity whereas, inertinite gets filled up as filler firmly implanted within different types of matrix. Their size association with other minerals also modify their behavior coke. Structured unstructured, smaller larger, high low reflectance, oxidation heat...
To produce low-cost hot metal, Tata Steel always had to deal with trilemma, that is, cost-quality-mining life achieve maximum benefit in the steel business. used approximately 50–60% Indian medium captive coking coal having 15–16% clean ash stamp charged blend. Keeping view, consumption, and preservation of by modulating without deteriorating coke quality was subject study. The study revealed 55% up 19.10% blend could be CSR ≥65. It also reduces cost added benefits increase mine life. This...
In spite of early learning phase stamp charge operation, the 1st battery Tata Steel achieved life more than 27 years and still having some residual life. Optimization coal blend on quality coke, health, cost along with modified standard operating practices well-designed oven health monitoring repair are backbones this achievement. Stamp charging technology has provided a high degree flexibility offered substantial savings in costs which, turn, had positive impact coke hence hot metal....
The preservation of coking coal and the reduction coke cost are gaining much importance in iron steel industry. An effort is being made worldwide to maximize use inferior quality cokemaking without sacrificing minimize cost. In general, Indian coals contain lower content vitrinite (≤ 50%) higher ash (≥ 15%) as compared imported coal. have poor washability characteristics also. Therefore, for making blend making, selection an appropriate proportion with a major challenge industries. Proper...
The coking process is based on the transformation of coal into coke at high temperature. In non-recovery oven, heating usually asymmetric, this may be due to fact that provided by controlled combustion volatile matter charged cake oven crown and sole flue.In present investigation, a simplified temperature profiles were simulated typical oven. selection criterions ovens time. Based measurement pattern, numerical methodology was proposed for predicting intermediate point using Lagrange...
The economics of the gas-based DRI unit depends on various factors, viz., quality and cost raw materials, reducing agents, operational efficiency CO 2 emission. Natural gas synthetic (produced from coal gasification) are used as reductants in direct reduction processes. In present study, authors have developed a methodology for utilizing surplus or waste coke oven place syngas thereby consumption gasifier to produce little bit greener steel. this process, is enriched by mixing adequate...
The production of hot metal through the blast furnace route is stilled most cost-effective and highly productive process probably remains coming decades besides developed many alternative ironmaking technologies. In recent past, working volume has been increased drastically to increase productivity. This means performance more correlated specific productivity which measures efficiency in terms ton metal. These modern furnaces favour high quality coke, i.e. coke CSR M40 value, iron content...
