                            <p>KARDEMİR Kok Fabrikalarında koklaşabilir kömür fırınlara şarj edilmekte, 18-21 sa.’lik koklaşma sonrasında elde edilen kızgın kok itici makina yardımı ile kılavuz arabası üzerinden söndürme vagonetine boşaltılmaktadır. Kızgın kok, söndürme kulelerinde su püskürtülerek söndürülmekte ve kok rampasına dökülmektedir. Metalürjik kok, kok kırma eleme tesisinde boyutlandırılarak yüksek fırınlara sevk edilmektedir. Yüksek fırın prosesinde kaliteli koklaşabilir kömürlerden elde edilen CSR değerleri yüksek metalürjik kok kullanımı tercih edilmektedir. Yüksek fırın prosesinde, kaliteli koklaşabilir kömürlerden elde edilen CSR değerleri %60-70 aralığında olan metalürjik kok kullanımı tercih edilmektedir. Fakat kaliteli kömür yataklarının rezervleri gün geçtikçe azalmaktadır. Bu çalışmada, düşük kalitedeki kömürlerden aynı verimi elde etmek için metalürjik koka çeşitli derişimlerde bor solüsyonları püskürtülerek CSR değerinin artırılması amaçlanmaktadır. Bu sayede metalürjik kok üretiminde kömür harmanı içerisinde düşük kalitedeki kömürler daha yüksek oranlarda kullanılabilecek ve hammadde maliyeti düşürülmüş olacaktır. Kok fırınlarında 1050 ± 50 °C sıcaklıkta elde edilen kızgın kok üzerine üç farklı bor ürünü ile çeşitli derişimlerde hazırlanan çözeltiler uygulanarak reaksiyon sonrası kok mukavemetindeki (CSR) değişiklikler üzerine etkileri incelenmiştir. Gerçekleştirilen uygulamaların kok reaktivite test sonuçları incelendiğinde, bor çözeltisi uygulanmış kok numunelerinin su püskürtülerek söndürülen kok numunelerine göre CSR değerinde %20-48 iyileşme olduğu gözlenmiştir. Optimum değeri veren 7 g/Ɩ derişimli Disodyum Oktaborat Tetrahidrat çözeltisi ile söndürülen kızgın kok numunesinin CSR değerinde %46.29 artış, CRI değerinde %34.92 azalış tespit edilmiştir.</p></trans-abstract>

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 °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/Ɩ concentration Disodium Octaborate Tetrahydrate solution giving the optimum value, was determined.</p></abstract>
