Blast Furnace Carbon Steel Forging Mild Steel Q345 For Bell Gear Ball Mill Gear

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

• 100% Ultrasonic Testing (UT) and MPI

• Mechanical test and material certificate provided with each order

Applications:

• Steel plant equipment (blast furnaces, converter charging systems)

• Mining and mineral grinding machinery (ball mills, rotary kilns)

• Other gear-driven heavy machinery requiring large-diameter, high-strength gear components

Manufacturing Capabilities:

• Advanced open-die and ring forging equipment

• In-house heat treatment & machining workshop

• ISO-certified quality control system

• Support for OEM & custom designs

The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.

Frequently Asked Questions (FAQs)

1. What size forgings can you produce?
Our forging capabilities cover a wide range—from 100 kg up to 7000 kg, depending on the shape and steel grade.

2. Can you handle heat treatment and machining in-house?
Yes, all heat treatment and machining processes (including rough turning and precision CNC finishing) are done in-house, ensuring quality and lead time control.

3. What types of industries use your products?
Our forgings are widely used in sectors such as:

• Wind energy (main shafts, gearbox components)

• Heavy machinery

• Port equipment and lifting systems

• Industrial transmission assemblies

• Mining, metallurgy, and oil & gas

4. How long does production take?

• If raw material is in stock: ~30 days

• If new material needs to be sourced: ~40–45 days
  We'll always confirm the timeline with your order.

5. Where are you based?
We’re located in Changzhou, Jiangsu Province, about 2 hours from Shanghai, with direct access to Shanghai Port for convenient global shipping.
