forged rolls manufacturing process

forged rolls manufacturing process is:

Electric arc furnace smelting → LF \ VD refining → ingot casting → annealing → cleaning → electroslag remelting → annealing → forging → post forging heat treatment → rough machining → preliminary heat treatment → semi finishing → dual frequency quenching or differential temperature treatment → cryogenic treatment → tempering → finishing → packaging and delivery.

Double refining + electroslag remelting to ensure good metallurgical quality

Perfect heat treatment and cold treatment technology to ensure the depth and hardness uniformity of hardened layer
