Product Description

Product Description

Bearing steel, also known as high-carbon chrome steel, has a carbon content of about 1% Wc and a chromium content of Wcr 0.5% to 1.65%. Bearing steel is divided into six categories: high-carbon chromium bearing steel, chromium-free bearing steel, carburizing bearing steel, stainless bearing steel, medium and high temperature bearing steel and magnetic bearing steel.

   Process Editing
(1) UHP electric furnace smelting with 50 tons or more → LF furnace refining with 60 tons or more → vacuum processing with VD furnace with 60 tons or more → alloy steel billet or rectangular billet continuous casting (260mm × 300mm, 180mm × 220mm) → slow cooling or Hot delivery → rolling material → finishing → inspection storage.
(2) Converter smelting at 90 tons or more → LF furnace refining at 100 tons or more → Vacuum treatment of RH furnace at 100 tons or more → Continuous casting of alloy steel billet or rectangular billet → Slow cooling at 320mm×340mm and 240mm×240mm Or hot delivery → rolling material → finishing → inspection storage.
