Title
Studies on the Manufacture of Formed coke for Blast furnace
박세윤 , 노강용 Se Yoon Park , Kang Yong Ro
Abstract
The production of formed coke has been realized in use of a non-coking coal as the main raw materials through the world, but It has not studied in our country about that. So I have studied the following two problems in order to develop the formed coke process. 1) Investigation of formed coke-process conducted through the world. 2) Studies on the production of a formed coke by using anthracite as a raw materials. As the result I have recognized the following three points. 1) The composition of ratio of raw materials was Jung Sung anthracite 74%, coking coal 16% (C. BI. 6) and added 10% of coaltar pitch. 2) Drum Test index (DI^(150)_(15) by JIS) had 85∼86% while conventional coke had 79∼80%. 3) Because of the uniformity of size, shape and weight of the formed coke, using in the blast furnace is convenient.
