Hot Rolling
Compact but versatile, the new compact hot rolling machine or NCH is made of a rough rolling machine and a finish rolling machine. From thick sheet steel to temperature-controlled coil, we apply our expert knowledge to hot working.
Hot Roughing Mill
Nippon Yakin’s roughing mill handles strip plate up to 25 millimeters thick as well as rough milling for short, thick plate metal, employing the first hydraulic automatic gauge control in Japan. This advancement allows Nippon Yakin to calculate the optimal rolling method for each product.

Steckel New Compact Hot Rolling Machine
This rolling mill is a Steckel type of finishing machinery capable of producing long hot strips with superior thickness precision, surface quality and internal quality. The hot roughing mill handles alloys that are difficult to roll as well as alloys with a high resistance to shape modification. Hot rolling is carried out in a furnace heated to at least 1,200° C under conditions set according to the desired product. The manufacture of high-functional materials encompasses a great deal of expertise such as the heating process of alloys not containing chromium. One such area of knowledge is the control of oxidation using a non-oxidizing furnace. This is particularly useful in the heating of Invar® alloys and soft magnetic alloys.

Pit furnace
The pit furnace applies heat to the slab in the plate rolling process.
The furnace is literally shaped like a pit. After the slab has been heated to the right amount, the top lid is removed and the slab is picked up and moved by crane and laid on a table for rolling.
Non-oxidizing furnace
This non-oxidizing furnace heats alloys with a primary composition of iron and nickel (Fe-Ni) in an original reducing atmosphere we developed.
Through this meticulous process, we produce high-performance alloys of the best quality.
