Technological developments in Japanese coke-making from 1950 to the 1980s -- Memories of an old researcher
- Nishi-Tokyo Univ., Yamanashi (Japan). Dept. of Management Engineering
The author will give a brief history of the technological developments in Japanese coke-making from 1950 to the 1980s. This period may be divided as follows: (a) The Mythological Age (1950--1960) when Japan imported US heavy coking coals such as Itmann, Keystone, etc. It was believed by coke plant engineers that good metallurgical coke could not be produced without such coals, because the blending of these coals with Japanese low rank high fluidity coals yielded unbelievably excellent coke. Their feeling for such US coals was so strong as to approach a kind of religious fervor. (b) The Groping Age (1960--1970) when Japan had a few means to research coke making, such as analytical data, Gieseler Plastometer and test coking ovens. Therefore, most of the studies were repeated ``trial and error``. (c) The Take-off Age (1970--1980s) when Japan introduced the very useful weapon for research into coal and coke -- ``Petrographic Studies``. It is no exaggeration to say that the application of petrographic studies was the most important factor in the technological developments of coke-making in Japan during this period. The blending design using many kinds of coal was able to achieve the minimization of the coke cost at that time, and it would have been impossible but for the studies.
