1. Multi-High Mills (KT/デュエルビッツ 評判ill)
12-High Mill (デュエルビッツ 評判ill)
Product Summary
デュエルビッツ 評判ill (Kobe Twelve-high Mill) is a high-performance rolling mill having the respective features of our 4-high and 20-high mills, which have excellent strip flatness functions, and corresponds to the demand of improved strip flatness.
Thus, the roll arrangement of KT Mill (12-high) dominates flatness control. In addition to that, KT Mill is equipped with a wedge-type hydraulic roll-gap control system, AFC (Automatic Flatness Control System) and KOS (Kobelco Operation Support system) which are developed by デュエルビッツ 評判teel. These features provide optimal rolling for the application of ultra-thin stainless steel foil, Fe-Ni alloy, titanium, copper, and so on.

Structure and Features of Multi-High Mills
1. Use of different diameters of work rolls
Rolling mill sizes are classified into regular series by roll diameters. Work rolls of different diameters can be used.
EX):KT160 adapts work roll diameters by 30 to 60mm.
2. Separated Housing Structure
Our multi high rolling mill has unique housing structure, which is separated into upper and lower parts and connected by four columns.
As a result:
- It is easy to watch over the front and back of the strip during rolling and to feed the strip.
- The rolling load is affected by the 4 columns. With a differential sensor attached to each column, accurate rolling load detection can be carried out.
- Accurate load detection can work effectively for our own developed hydraulic Automatic Gage Control (AGC).
- Tilting-rolling by individual screw-down at the drive side and work side is possible, and is preventing strip telescoping and modifying asymmetrical flatness.
3. High gauge thickness control by Wedge-Type Hydraulic Roll-gap Control Mechanism
Roll-gap Control is performed by the hydraulic cylinder connected to a wedge built in the rear side of the back-up rolls of the lower housing. Mill housing receives rolling load directly through the wedge, so that a high-rigidity hydraulic push-up is possible. Moreover, the wedge-type hydraulic roll-gap control device achieved the world top-level high-speed control and adapts quick displacement control of strip thickness.
4. Uniform Product Shape with Various Flatness Control Mechanisms
Our 12- or 20-high rolling mill is equipped with such adjusting mechanisms as crown, intermediate roll lateral, and tilting-rolling for flatness control measurement. In addition, feed back control is possible with the Automatic Flatness Control System (AFC).
