Development of the super coke oven for productivity and environment enhancement toward the 21st century (SCOPE 21); Sekitan kodo tenkan cokes seizo gijutsu no kaihatsu

Abstract

Serious shortage is predicted on cokes for blast furnaces in the first half of the 21st century. In order to deal flexibly with the fluid world market in the future, it is necessary to have a technology developed, by which coals from coking coal to non-coking dust coal can be used. The Japan Iron and Steel Federation and the Center for Coal Utilization, Japan are working on research and development of a new process with enhanced environmentality and economy (SCOPE 21) as a coke manufacturing process to respond to the requirements arisen from the above situation. The process is assessed basing on basic technological seeds such as rapid coal heating and high-speed carbonization and reformation of middle to low temperature cokes. The organizations are moving forward an eight-year development program which has started in fiscal 1994. This paper reports the summary of the development, and results of investigations and researches performed during fiscals 1994 and 1995. Rapid heating tests, middle to low temperature coke reformation tests, and tests for plug transportation of high-temperature coal have been performed. It has been verified, for example, that rapid coal heating can improve coke strength. The development work is being promoted toward grain size  More>>
