dc.description.abstractIn the Coke Plant of KARDEMIR, coking coal is charged to the furnaces, the hot coke is obtained after 18-21 hours of coking is discharged to the quenching wagon via the guide car with the help of the pusher machine. The hot coke is quenched by water spraying in the quenching towers and is poured into the coke ramp. The metallurgical coke is sized in the Coke Crushing and Screening Plant and sent to the blast furnaces. In the blast furnace process, the use of metallurgical coke with high CSR values obtained from high quality coking coals is preferred. In the blast furnace process, it is preferred to use metallurgical coke with CSR values in the range of 60-70% obtained from high quality coking coals. However, the reserves of high quality coal beds are decreasing day by day. In this study, it is aimed to increase the CSR value of metallurgical coke by spraying various concentrations of boron solutions in order to obtain the same efficiency from low quality coals. In this way, low quality coals in the coal blend in metallurgical coke production will be used at higher rates and raw material costs will be reduced. Solutions prepared with three different boron products and various concentrations were applied to the hot coke obtained at 1050 +/- 50 degrees C in coke ovens, and its effects on the alteration of coke strength after reaction (CSR) values were investigated. When the coke reactivity test results of the applications were examined, it was observed that there was a 20-48% improvement in the CSR value of the coke samples with boron solution compared to the coke samples quenched by spraying water. A 46.29% increase in CSR value and a 34.92% decrease in CRI value of the hot coke sample, which was quenched with 7 g/l concentration Disodium Octaborate Tetrahydrate solution giving the optimum value, was determined.en_US
