developments in blast furnace iron making. Introduction Kobe Steel started operation as an integrated steel manufacturing company with the blowing-in of the No. 1 blast furnace (BF) at the Kobe Works in 1959.1) We, as latecomers, faced an issue with burden materials, which forced us into high pellet ratio operation requiring central gas flow. A

Kobe Steel's history of pelletizing plants began when the company built a plant at its Kobe Works in 1966. This paper introduces the history of pelletizing plants, including process outlines and the latest achievements in the construction of plants overseas. In the past, plant owners had focused mainly on the quality of the product
JFE manufactures tin mill products under strict operating in order to meet customer requirement. For example, since the inclusion defect in substrate is controlled in steel making process and thickness proﬁle is controlled in hot and cold strip mill, JFE's tin mill products can be applied to Drawing
The Bessemer Process was invented and patented in 1855 by Henry Bessemer. This was the first inexpensive industrial process to make steel from molten pig iron. Although the process had been used outside Europe for hundreds of years before this, this was the first time it was used on an industrial scale.

To produce the fabric or steel belts, fabric or steel cord must go through a calendering process—an operation in which the rubber compound is pressed on and into cords. Because the bonding of fabric to rubber or steel to rubber is critical to performance, the calendering process is an important step.
－ 2 － 1.2.3 Nozzle structure Open nozzle is common when molding NOVADURAN. The nozzle of commercially-supplied injection machine can be open nozzle or shut-off nozzle (Figure 1-1) but in any type, it is necessary to have a temperature control.
strength steel sheets (590 to 1,470 MPa) to automotive parts.4-5) 6) Considerable volumes of high-strength steel sheet have already been applied to not only reduce the weight of car bodies but also enhance their crashworthiness. It is expected that efforts to further reduce car body weight by making most effective use of high-strength steel

This is very process efficient because canit use high currents from 500 to 1300 amperes, thereby obtaining deeper weld penetration into the base metal. This process, therefore, is suitable for welding thick-section steel materials. The equipment for and principle of this process are shown in Fig. 1.3.
