Production Volume Increase
High speed rolling technology
Increased production volume and stable operations become possible through high speed rolling technology.
Block mills
Using a block mill, which drives multiple rolling mills and has been used on 100m/s class wire rod lines, as the bar steel finishing mill, will achieve speeds far beyond the finishing speed of about 20m/s that was the limit of conventional mills. Rolling using ultra-hard rolls provides advantages such as precise measurements and enhanced surface finish.Additional advantages are easier roll exchange and maintenance.
High Speed Dividing Shears (HSDS)
Ordinarily, shears were start-stop types, which began moving when the shearing point arrived. However, there was a limit to the speed of the blade rotation (shearing speed) because the blades went from a standstill then began rotation and acceleration. Continuous rotating shears were adopted for the HSDS system, enabling faster shearing speeds. This makes stable shearing possible at even faster rolling speeds.

EBROS™ stands for Endless Bar Rolling System. Its objective is to enhance productivity and yield ratios.
Simply put, the function of the EBROS™ is to weld the heads and tails of the billets that are extracted at constant intervals from a reheating furnace, and to create a billet of unlimited lengths.
- It enhances productivity by doing away with gap time
- It does away with cropped items or items of irregular lengths
- It reduces miss-rolls and enables uniform quality

Production Cost Reduction
HDR (Hot Direct Rolling) is a system where the billet from a continuous casting facility is conveyed through roller table and directly input into a mill without being reheated. It is an excellent energy-saving technology.
For the realization of this HDR system, comprehensive engineering capabilities for furnaces and continuous casting and rolling facilities are required. Such includes (1) high-temperature casting technology; (2) technology to minimize the temperature decrease; and (3) optimal layout for delivery to the next process.
We, Steel Plantech, will make the utmost use of these comprehensive engineering technologies to meet our customers’ needs.
