  • Melting

 

The alloy ingot for the blank of the forged steel rolls is usually melted by electric arc furnace. Through the oxidization, restoration and adjustment to the ingredients of the steel liquid, slagging reaction and slagging-off will reduce the content of harmful elements, thus to get qualified steel liquid. The demoulded steel ingot can go to next step after its surface is finished and cleaned.

 

 

  • 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.

 

  • 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
