Koklaşmayan Armutçuk ve Amasra kömürlerinin Geliştirilmiş Briket Şarj Yöntemi (Sumi-Coal System) ile metalurjik kok üretiminde kullanılması olanakları pilot çapta araştırılmıştır. Bu yöntemin uygulanması ile demir-çelik sektöründe kullanılmakta olan iyi koklaşabilir Zonguldak kömüründen veya ithal edilen yüksek kaliteli kömürlerden önemli ölçüde tasarruf etmek mümkün olacaktır. Araştırma çalışmasının sonucunda şu neticelere varılmıştır: Armutçuk ve Amasra kömürleri Geliştirilmiş Briket Şarj Yöntemine uygun kömür cinsleridir; (2) Bu yöntemin uygulanmasıyle % 25-30 oranında Armutçuk kömürü ve % 15-20 oranında Amasra kömürü Zonguldak veya ithal kömürlere ilâve edilerek metalurjik kok üretiminde değerlendirilebilir. Elde edilen kokların parça büyüklüğü, mekanik sağlamlığı, yoğunluğu, porozite ve reaktivite değerleri yüksek fırın operasyonunda hiç bir işletme problemine neden olmayacak özelliklerdedir; (3) Bu çalışmada birçok faktörün tam olarak bilinememesinden dolayı fizibilite çalışması için oldukça basit kabuller yapılmıştır; fakat projenin gerçekleşmesi yönünden önem taşımaktadır. Kullanılan dataların bir kısmı Ereğli Demir ve Çelik Fabrikalarından, diğer bir kısmı da Japonya'daki gerçek operasyon şartlarından alınmıştır. Ereğli Demir ve Çelik Fabrikalarının ham çelik üretimi 2.0 mil. T/y, pik demir üretimi 1.5 mil. T/y ve toplam kok tüketimi 1.1 mil. T/y olarak saptanmıştır. Operasyon kok fırınlarının üzerindeki kömür kulesine bağlı şarj konveyörüne göre zamanlanarak briket bunkeri yapımından tasarruf edilecektir. Koklaşmayan kömür, mevcut bulunan ana kömür bunkerinden alınacak ve parça büyüklüğü % 80 i - 3.0 rnm olacaktır. Bütün mekanik, elektrik ve enstrumental ekipmanın Japonya'dan FOB fiyat üzerinden temini öngörülmüştür. Koklaşabilir Zonguldak kömürü 14 900 TL/t, koklaşmayan Armutçuk 13 200 TL/t, Amasra kömürü 9 200TL/t ve zift 25 000 TL/t fiyatı üzerinden yapılanfizibilite çalışmalarına göre bu proses Ereğli Demir ve Çelik Fabrikalarında uygulanırsa, kısa bir süre içerisinde kendini karşılayacaktır. Zonguldak kömürüne % 25 oranında Armutçuk katılarak ton kok başına 1.0 US $, % 20 Amasra kömürü katılarak 3.0 US $, koklaşan ve koklaşmayan kömürlerin ithal edilmesi halinde ise 6.0 US $ tasarruf sağlanabilecektir.

In this work, the possibility of utilizing the non-coking Armutçuk and Amasra coals for metallurgical coke production through the Sumi-Coal Improved Briquette Charging Method has been investigated. The successful implementation of the said process would resold in considerable saving in the consumption of coking Zonguldak coal or the high quality imported coals. Results of the research are as below. Both Armutçuk and Amasra coals are suitable for the Sumi-Coal process. As far as the coke size, mechanical strength, density, porosity, reaktivity and chemical analyses are concerned about 25-30 % of Armutçuk or 15-20 % of Amasra coal can be used in the metallurgical coke production by the application of the Sumi-Coal process, without creating by operational difficulties in the blast furnace. The feasibility study of this work is not so simple because of too many unknown factors. However, the feasibility study carried out, under the following condition: Basic data were from actual operating results in Japan. The price estimation of the equipments given by a Japanies expert were based on 1979, prices. The feasibility data were based on 1.5 X 106T/y pig iron and 2xl06T/y crude steel and total coke consumption 1.1 x 106T/y. The operation is to be syncronized with that of the charging conveyor to the coal tower of the coke oven. Non-coking coal, as material shall be received in the existing main coal bunker and its size shall be 80 % under 3 mm. All utilities necessary for this plant shall be supplied by Ereğli works. Supply of all the mechanical equipments market flow sheet and corresponding electric and instrumentation equipments at FOB Japan basis. The price of coals and utilities are for Zonguldak coal 14,900 TL/t, Armut9uk coal 13,200 TL/t and Amasra coal 9,200 TL/t and 25,000 TL/t for pitch. For the imported are 100 $/t coking coal and 70 $/t non-coking coal. From the result of this feasibility study, can be considered the following profit: When the perscentage of Armutçuk coal added to the Zonguldak coal was possible, a saving of 1.0 US $ per ton of coke was predicted when Amasra coal was added to the Zonguldak coal in ratio of 20 %. If both of the coking and non-coking coals were imported a possible saving of 6.0 US $ per ton of the coke produced would be expected.
