Application & Industry Focus
What a 20m³ Large Slag Pot Does in Your Large BOF shops
Our custom 20m³ large slag pot castings serve as core components in large bof shops, slag granulation lines, ferroalloy plants — engineered to withstand high loads, continuous wear and extreme thermal or mechanical cycling while maintaining the operational stability of heavy machinery.
Because every heavy machinery project demands unique dimensions, we do not restrict your design to standard specification charts. We translate your 2D/3D engineering drawings into robust physical components with chemistry (ZG230-450, GS-20Mn5) tailored to your wear-resistance and tensile requirements.
Common Applications & Machinery Served
- Large BOF shops
- Slag granulation lines
- Ferroalloy plants

How do you prevent internal defects like blowholes, sand inclusions, and cracks in large steel castings?
We eliminate internal defects through a multi-stage control system. First, we use Ladle Furnace (LF) refining to degas and purify the molten steel, strictly limiting sulfur and phosphorus levels. Second, we optimize the gating system using casting simulation software. Finally, every critical area undergoes 100% Non-Destructive Testing (NDT), including Ultrasonic (UT) and Magnetic Particle (MT) testing, ensuring zero critical defects before shipment.
What in-house Non-Destructive Testing (NDT) capabilities do you have?
Our in-house NDT laboratory is fully equipped and certified. We perform Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and Liquid Penetrant Testing (PT). For special requirements, Radiographic Testing (RT) can also be arranged. All our NDT inspectors hold international certifications (Level II or Level III) to guarantee inspection accuracy.
How do you guarantee the stability and consistency of mechanical properties across different batches?
Consistency comes from standardized heat treatment and digital microstructural analysis. We utilize large, computer-controlled natural gas heat treatment furnaces to perform precise annealing, normalizing, and tempering. Every heat code is tracked, and samples from the same pouring batch are tested for tensile strength, yield strength, impact toughness, and hardness to ensure they perfectly match your specifications.
Can you provide full material traceability and Material Test Reports (MTR)?
Absolutely. Every casting is stamped with a unique Heat Number for lifetime traceability. With each shipment, we deliver a comprehensive document package including Material Test Reports (MTR) complying with EN 10204 3.1, chemical analysis reports (via direct-reading spectrometer), mechanical testing data, and NDT clearance certificates.
What is your typical lead time for a custom heavy steel casting like a slag pot or girth gear?
For large customized castings, the lead time generally ranges from 45 to 75 days, depending on the geometric complexity, pattern-making requirements, and the level of final machining needed. Once the engineering drawings are approved, we provide a detailed project timeline and send weekly progress photos/videos to keep you updated.
Can you manufacture castings that strictly comply with our local standards (e.g., ASTM, DIN, EN, JIS)?
Yes. We are highly experienced in international standard conversions. Whether your project specifies American standards (ASTM A27, ASTM A148), European standards (EN 10213, DIN GS-20Mn5), or Japanese standards (JIS G5101), our metallurgical engineers will configure the exact chemical composition and heat treatment parameters to meet or exceed those requirements.
