Carbon Steel Forgings For Blast Furnace Bell Gear Ball Mill Gear. We manufacture heavy-duty carbon steel forgings engineered for use in blast furnace bell gears and ball mill gears. These components are critical for high-load, continuous-operation environments such as metallurgy and mining industries, where strength, durability, and dimensional stability are essential.
Material Options:
C45 / C50 – Medium carbon steel with excellent tensile strength and wear resistance
Q235 / Q275 – Low carbon steel options for structural integrity and cost-efficiency
Other carbon steel grades available on request, based on application requirements
Product Types:
Bell gear forgings for blast furnace charging systems
Large gear blanks or semi-finished gears for ball mills
Customized round, ring, and disc-shaped forgings according to client drawings
Key Features:
Weight range: 100 – 7000 KG
Forged with uniform grain flow and refined internal structure
Heat treatment options: normalizing, tempering
Delivered in as-forged, rough-machined, or pre-machined condition
