The Backbone of Industrial Manufacturing: Heavy Steel Castings
At Hanhai Casting, we design and manufacture heavy steel castings that perform under harsh conditions—high loads, heat, abrasion and impact. From rotary kiln tyres and girth gears to mill housings and crusher frames, our heavy steel castings deliver long service life, stable alignment and reliable throughput for mining, cement, metallurgy and power generation.
Heavy Steel Castings in Mining and Cement Industries
- Mining: crusher frames, wear plates, liners, mill trunnions—optimized for impact and abrasion in continuous duty.
- Cement: rotary kiln tyres, girth gears, riding rollers, mill housings for 24/7 operation.
- Metallurgy: high-temperature components with dimensional stability for steel plants and foundries.
- Power Plants: coal mill parts, boiler support castings and structural components.
Our heavy steel castings ensure long service life and stable performance under continuous heavy-load conditions, helping plants reduce unplanned downtime.
Our Heavy Steel Castings Product Range
- Rotary Kiln Tyre / Riding Ring – large diameter, anti-ovalization design.
- Girth Gear – precise tooth geometry; matched with pinion & shell.
- Mill Housing & Trunnion – high rigidity for mills and grinding units.
- Crusher Frame & Base – impact-tough structures for primary/secondary crushers.
- Wear-Resistant Castings – liners, hammers, segments and customized parts.
We supply heavy steel castings such as rotary kiln tyre casting, large girth gears, and crusher frame castings widely used in mining and cement plants.
Material and Process Control for Heavy Steel Castings
We operate a full process chain from pattern making to finish machining. Every heat is traceable with MTR and NDT records. Reference: Steel Casting (Wikipedia).
| Step | Key Controls |
|---|---|
| Material Selection | Low-alloy steel, high-Mn steel, heat-resistant steel; spectrometer check & sample coupons |
| Molding & Casting | Feeding-system simulation, riser/vent design, controlled solidification |
| Heat Treatment | Normalizing, quench & temper; hardness & microstructure verification |
| Machining | CNC boring/turning, gear cutting; GD&T control for concentricity & run-out |
| NDT & Final QA | UT/MT/PT, dimensional inspection, dynamic balance (if required), MTR & NDT reports |
Typical Specifications for Heavy Steel Castings
- Max single-piece weight: up to 30–50 t (project-dependent)
- Diameter capability: up to 6–10 m for rings/gears
- Tolerances: per drawing / ISO / AGMA for gearing
- Certificates: ISO 9001; third-party inspection available (BV/SGS/TUV)
Why Choose Hanhai Casting for Heavy Steel Castings
- Engineering support: DFM, material recommendation and on-site service.
- Stable delivery: optimized foundry scheduling and machining cells for critical paths.
- Lifecycle value: durable castings reduce stoppages and maintenance costs.
Result we aim for: longer service life, fewer stoppages, precise alignment and predictable maintenance windows for your plants.
Frequently Asked Questions
Can you produce per our drawing and standard?
Yes. We manufacture strictly to customer drawings and referenced standards (ISO/ASTM/AGMA). Reverse engineering is available.
What test documents can you provide?
MTR (chemical & mechanical), NDT (UT/MT/PT) reports, heat-treatment charts, dimensional reports, and third-party inspection upon request.
Do you support OEM/ODM and small trial orders?
Yes. We handle both replacement parts and new-project development with staged samples and PPAP if needed.
