DUAL  HARDNESS  LINERS

Romani has developped and efficient technology for the construction of Liners and Wear Parts: the SURFACE HARDENING.
The double hardness obtained, can guarantee high wear resistance on the outer hard side of the plate and vibration and shock absorption on the soft unhardened side.

The materials:

• AR/38 Standard
  

Basic material: Carbon Steel.

Hardened TOP side 60±2 HRC, depth 3-5 mm;

Soft BOTTOM side ∼180 HB

• IX/43, ANTICORROSION.

Basic material: STAINLESS STEEL.

Hardened TOP side 56±2 HRC, depth 3-5 mm;

Soft BOTTOM side ∼200 HB

• AR/38-S Standard PLUS. Ideal for roughing stands
  

Basic material: QT Alloy Tool Steel.

Hardened TOP side 60±2 HRC, depth 3-5 mm;

Soft BOTTOM side ∼180 HB

Other grades like THROUGH HARDENED TOOL STEEL, BRONZE ALLOYS, COPPER ALLOYS, CAST IRON and OTHER ALLOYS also available.

Perfect FLATNESS!! Another important parameter that we guarantee in order to meet perfect matching with mating surface and equal distribution of loads to chocks and housing.

The plates:

• Housing liners
• Back up roll chocks liners
• Work roll chock liners
• Rocker plates
• Sliding liners made in different alloys
• Bottom liners (bending blocks, pressure plates, Step Liners etc..)
  
• Shifting Blocks
• Top Liners
• Others
