what are forged rolls?

Forged rolls is a metallurgical term, including smelting, ingot casting, forging, cold rolling work rolls and backup rolls.

forged roll manufacturing process

Including smelting, ingot casting, forging, and cold-rolled work rolls and back-up rolls with high requirements for post-forging production. Since the 1960s, the main processes of steel heat treatment, rough machining, final heat treatment, and finishing. Raw cladding refining furnaces have also begun to be used for the smelting of roll steel. The selection and control of equipment and process parameters for electric furnaces, open hearth furnaces or Shanghai-made forged rolls provide rough-smelting molten steel with low phosphorus and chemical composition close to finished steel. During refining, it must ensure that the chemical composition, mechanical properties, and requirements of finished rolls are satisfied. Microstructure, desulfurization in the furnace, fine-tuning the composition, removing hydrogen, nitrogen, deoxidation metallurgical quality, dimensional tolerance, internal stress distribution and surface state after vacuum treatment and eliminating inclusions, can obtain relatively pure molten steel. Ingots were cast under nitrogen protection. Or pour under vacuum.

rolling mill rolls

Are classified by material as follows:

(1) Forged alloy steel roll;  

(2) Forged semi-steel rolls;  

(3) Forged semi-high-speed steel rolls;  

(4) Forged white cast iron rolls.
