Abstract
Recently, Japan has made remarkable technical progress in iron & steel industry, and near future, gigantic blast furnaces, such as 10, 000t/D pig will be constructed.
So, it is demanded to tie up with these B. F to develope the giant-scale coke ovens with higher productivity.
Since '61, we have gradually enlarged from 4 m height to 6 m height, and been operating at Wakayama Works.
By the analysis of various conditions and the operating experience at Wakayma, we designed and errected at Kashima New Works, the giant-scale coke battery, with 180 ovens, named Koppers-Sumitomo Type, one of the world-largest, with 7, 125mm height, 460mm width, 16, 500mm length, 48.3m3 in effective chamber volume.
Besides, it has many specific charactors, i.e., vertical uniform heating system, carbon deposit control system, and etc.
We are now keeping the smooth operation with 17.1hr coking time, since the starting up on 6 th, January, '71.
