Mill roll
We supply forged steel rolls for hot rolling and cold rolling, and a full range of steel types for various rolling processes.
Outline
With mill rolls for sheets as the main products, we are capable of making forged steel rolls for hot rolling and cold rolling. In addition, we supply a full range of steel types for various rolling processes. Our manufacturing facilities make full use of unique know-how in a system that meets users' needs with close cooperation between our research and development, manufacturing, technical services, and sales units.
Our product quality has long been of the top class in the world. Our high-speed mill rolls, which have superior anti-burning characteristics due to control of high-chrome carbide substances, and CPI rolls, which can reduce cost while still maintaining the same level of high quality, are highly evaluated by customers.
Characteristics
Forged steel hardened roll
Standard work roll
- CPI roll
We have reduced costs to a minimum by carrying out process improvements. High cost performance is achieved with the same functionality as the conventional 5Cr standard type. Hardened depth φ60 - CPI-SD roll
With the same basic rolling performance as CPI roll, the hardened depth has been increased to φ80.
High performance work roll
- CGL roll for special uses
Spalling is prevented with hydrogen embrittlement - Scratchless roll
Uniformity of ground surface roughness, good grindability - High-speed mill roll
The frequency of burning under high-speed and high-pressure rolling is reduced by controlling the distribution of carbide substances. - High toughness, semi high-speed tool roll
This steel can be used for many manufacturing applications such as high abrasion-resistance, good defect-prevention performance and good grindability.
High-performance intermediate roll
Abrasion-resistant hot dies intermediate roll, abrasion-resistant high chrome intermediate roll
Base strengthened backup roll
The anti-destruction toughness of this forged steel backup roll has been greatly enhanced by improving the hardening process and adjusting the alloy components.
