Calcined Coal Recarburizer
"The Economical & Efficient Carbon Choice for Robust Applications"
Fengyang Metallurgical: Calcined Coal Recarburizer
🔍 "The Pure Carbon Solution for Superior Metal Quality"
"Powerful Carbon from the Earth: Tough, Reliable, Affordable!"
Calcined Coal Recarburizer is produced by high-temperature treatment of selected anthracite or bituminous coal to reduce volatile matter. It is characterized by good carbon content, natural graphitizing tendency, and highly competitive pricing, making it an excellent economical alternative for many cast iron and steel applications.
Why Choose Our Calcined Coal Recarburizer ?
"Maximize Your Output, Minimize Your Costs!"
💸 Exceptional Economy: Offers the most cost-effective carbon addition per unit, ideal for price-sensitive production.
🏭 High Performance in Iron: Well-suited for gray iron and some ductile iron grades, with good absorption in iron melts.
🛡️ Natural Inoculation Effect: Certain trace elements in coal can have a mild inoculating effect on iron.
📦 High Bulk Density: Results in less dust and easier handling compared to some lighter alternatives.

Production Process & Quality Control
"Harnessing Natural Carbon with Modern Precision!"
- Coal Selection: Careful sourcing of low-volatility, high-carbon coal.
- Shaft Kiln Calcination: Calcined in vertical or rotary kilns at controlled temperatures to achieve target fixed carbon.
- Quality Sorting: Post-calcination sorting to remove uncalcined material and high-ash pieces.
- Sizing & Grading: Processed through breakers and screens to achieve uniform, market-preferred sizes.
- Rigorous Sampling: Representative samples from each batch are analyzed to guarantee specification adherence.
Key Application Areas
"The Strong Backbone for High-Volume Production!"
- Gray Iron Casting: Extensively used in automotive brake discs, engine blocks, and municipal castings (manhole covers).
- Steelmaking (Basic Grades): An economical carbon source for long product steel mills (rebar, wire rod).
- Ferroalloy & Silicon Metal: Used as a reducing agent and carbon source in submerged arc furnaces.

Frequently Asked Questions (FAQs)
"Straight Answers for Smart Buyers!"
Q1: Is the ash content manageable?
A: Yes, our controlled ash level is factored into efficient slag practice. It's suitable for applications where slightly higher slag volume is acceptable.
Q2: Can it be used for ductile iron?
A: It can be used for some lower-grade ductile iron, but for high-quality SGI, Graphitized or Low-S CPC is recommended due to sulfur concerns.
Q3: What is the carbon recovery rate?
A: Typically 85-90% in iron melts, depending on application method and furnace conditions.
Q4: Do you offer different fixed carbon grades?
A: Yes, we offer standard (FC≥90%) and premium (FC≥93%) grades to suit different requirements.
Q5: How does moisture affect the product?
A: We strictly control moisture to below 1% to prevent steam explosions and ensure accurate charging weights.
Q6: What's the lead time for a 1000-ton order?
A: For large orders, we can arrange staggered shipments. Typically, we can commit to 300-400 tons per week.
Q7: Is the product dusty?
A: Our product has low fines content due to careful handling, but standard dust control measures during handling are always advised.
Q8: Can you provide a blend of lump and nut sizes?
A: Certainly, we can create custom blends to optimize furnace performance and dissolution rates.
Q9: What's your payment term for new customers?
A: Standard terms are T/T in advance or L/C at sight for the first order.
Q10: Do you have references from users in [Customer's Country/Region]?
A: We have a global clientele. Please inquire, and we can connect you with a reference in a similar industry where possible.
