Six blast furnaces now are operating in Yawata Iron & Steel Works : No.4 (350t/day), No.5 (400t/day) and No.6 (400t/day) at Higashida and No.2 (700t/day), No.3 (1000t/day) and No.4 (1000t/day) at Kukioka. The No.5 furnace at Higashida produces foundry pig iron and the other furnaces the basic pig iron to be used for steel plants. Recently, the operating results of these furnaces have rapidly been improved and coke ratio has also decreased down to about 0.7. Especially, the 1000t/day furnace has been producing practically from 1000t/day to 1250t/day since July 1953, while their output before the War was only about 800t/day, In spite of the coke-ash being 13%, the iron-making by each furnace in the Yawata Iron & Steel Works is showing a favorable operation and stands almost on a level of the European and American standard. This is presumed mainly due to the sizing of raw materials, the extended equipment of the sintering plant and an improvement in the coke-behavior.
