Sheet Production Equipments with Distinctive Advantages
Endless hot rolling
“Endless rolling” at Chiba No. 3 continuous hot strip mill
Endless rolling is a "dream technology" which enables continuous rolling of hot strips by in-line welding of sheet bars with 30-40mm thickness, thereby realizing stable rolling and also making it possible to develop new products.

Super-OLAC Equipment
Fukuyama No.1 hot strip mill realizes the world highest cooling speed by “Super-OLAC H”
“Super-OLAC H”in Fukuyama No.1 continuous hot strip mill
Super-OLAC H at Fukuyama realizes the theoretically marginal world’s highest cooling speed (700°C/sec at 3mm thickness) and uniform cooling over the strip surface. The new facility features high accuracy cooling rate control and improves uniformity of material quality such as high strength, high toughness, stable weldability and formability.
“Super-OLAC H” is an abbreviation of Super On-Line Accelerated Cooling for Hot Strip Mill
Fully Continuous Pickling and Cold Rolling Line
Fully continuous cold strip millLinkage and synchronizing operation of the pickling process and a fully-continuous tandem cold rolling mill enables stable production of cold-rolled steel sheets with higher quality.
Continuous Annealing Line for Sheet
Continuous annealing lineThe continuous annealing line (CAL) developed by JFE Steel for sheet products realizes high productivity and quality stability and has the capability to produce a wide range of product types from mild steel to ultra-high tensile steel.
