the iron and steel industry with respect to geographic distribution, plant size, and processes used. Fourteen of the installations in the iron industry were operated as mineconcentration plant combinations, although in some places the distance from the mine to the concentra tion plant was a few miles. Only one mine and one concentration
Iron and Steel Emissions. Iron and Steel Emissions. Iron is believed to be the sixth most abundant element in the universe, and the fourth most abundant on earth. The concentration of iron in the various layers in the structure of the Earth ranges from high (probably greater than 80%, perhaps even a nearly pure iron crystal) at the inner core, to only 5% in the outer crust.
The Chinese government specified coke dry quenching technology as one of the targets in the Tenth 5year plan in 2000. Coke dry quenching technology was also a key project during the Eleventh Five Year Plan period (2006 to2010), where during this period the iron and steel integrated enterprise should practice coke dry quenching.
Dry quenching. During dry quenching the hot coke is cooled down in a closed cooling chamber by use of an inert gas which is circulated and cooled down thereby within a heat exchanger. The produced steam can be used for electricity production. A scheme of a dry quenching plant is shown in Fig. 20.

(31) With Series 9, soft toolsteel, we get like results (group IV. of Tables 18 and 19). At the beginning of the recalescence, at its crest, and even when the temperature has begun to sink from its crest, so much of the hardeningpower remains that the steel, when quenched after slow cooling to these points, has not acquired any measurable ductility, nor has its tensile strength .
In 1976, we constructed the first CDQ plant at the Yawata Works of NIPPON STEEL CORPORATION, with a capacity of 56 t/h. Since then, we have not only recorded a large number of construction achievements, but we have also expanded this technology to other countries, constructing more than 110 CDQ plants all over the world.
