‘MITSUBISHI-HITACHI’ (PRIMETALS) 2,300 mm Wide Hot Strip Mill

Make: ‘MITSUBISHI-HITACHI’ (PRIMETALS) 2,300 mm

Hot Strip Mill

The Hot Strip Mill at JFE Steel’s Keihin district stands as a testament to cutting-edge steel production technology, boasting the capability to manufacture Japan's widest hot-rolled steel strip. Commissioned in 1979, the mill has been continually upgraded throughout the years to maintain its competitive edge. Production ceased in September 2023, leaving behind a legacy of excellence.

It features a Pair Cross Shift Mill for adaptive roll gap control to optimize thickness and shape. A key enhancement was the integration of a Sizing Press in 2009, which allows for variable strip widths while using slabs of constant width. This not only increases the productivity of the slab caster and reheating furnace upstream but also expands the range of products that can be manufactured efficiently.

Capable of rolling slabs measuring up to 2,300 mm in width, with thicknesses ranging from 160 to 250 mm, the Keihin HSM has an annual production capacity of approx. 4,000,000 tons. The mill processed low-carbon steel into a variety of products, from thin sheets for automotive bodies to thicker plates for line pipe applications.
