3. Forging

The qualified steel ingot is pressed to the roll blank by the hydraulic forging machine after pre-heating, heating and even heating.

The purpose of forging and pressing process is: the forging and pressing can reduce and compress the porosity, shrinkage and some pore; improve the macroscopic segregation (pattern segregation, V shape segregation) in the original structure of the steel ingot; shatter the gross liquation carbide and net carbide; crush and refine the gross grain.

In order to acquire the optimized feature of the roll, we strictly control the forging ratio , not less than 3 for work rolls while more than 2.5 for large size backup rolls.

4. Electro Slag Remelting

Electro slag remelting (ESR) is a specialized steel-making process in which a cast ingot in the form of an electrode is re-melted in a water-cooled copper mould. The melting is activated by resistive heat generated in a conductive slag.

Charactersistics of ESR:

1. No macroscopic segregation and few microscopic segregation. Very few and subtle non-metal inclusion; dispersed distribution.

2. Compact and homogeneous structure

3. High toughness and strength

4. Beneficial for improvement of anti-fatigue and heat impact ability of the roll
