Product Details

Forged Steel Work Rolls

Forged steel cold-rolled work rolls are important components of strip cold-rolling mills, and their properties directly affect the shape, surface quality and rolling production efficiency of cold-rolled sheets.

Application: Widely used in various domestic and foreign single-stand and continuous rolling mill units, rolling different products such as automobile sheet, silicon steel, stainless steel, aluminum foil and so on.

Forged steel roll technical Process:

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
