Construction of Tobata's No.1 blast furnace was started in June 1957. It was constructed as the first step under the second modernization and expansion program of Yawata Iron & Steel Co. Ltd. and blown-in on September 1, 1959. It has a nominal capacity of 1500t/d-1603m^3 in inner volume and 8.8m in hearth diameter-and is the largest blast furnace in Japan. This plant has many characteristics in its layout, harbour establishments, ore-treating system, charging facilities as well as in the type of the furnace and so on. Since blown-in, it has been operated very smoothly for about a year, and iron production was increased without any difficulies and now attained to about 2000t/day. On the other hand, Tobata's No.1 sintering machine was started in Septembr 1960. This machine is going to produce more than 3500 t self-fluxing sinter per day and will render services to promote the productivity of the furnace. Besides, Tobata No.2 blast furnace is expected to be blown-in in October 12, 1960.
