Metallurgical fluorspar lumps 10-50mm CaF2 90% supplier

Product Specification

Product Overview

Our Metallurgical Fluorspar Lumps (10-50mm, CaF2 90%), also known as Met-spar, is a high-grade mineral flux widely utilized in global heavy industries. Sourced from premium fluorite deposits, this product features excellent thermal stability and chemical consistency, making it an indispensable slag conditioner for modern steelmaking, electric arc furnaces (EAF), and ferroalloy production.

With a guaranteed minimum CaF2 content of 90%, our fluorspar lumps efficiently lower the melting point of slag, remove impurities like sulfur and phosphorus, and optimize overall metallurgical efficiency.

Technical Specifications (Typical Analysis)

To ensure the highest quality for your metallurgical processes, our fluorite lumps strictly adhere to international industrial standards.

Key Benefits & Industrial Applications

1. Advanced Slag Conditioning in Steelmaking

In Basic Oxygen Furnaces (BOF) and Electric Arc Furnaces (EAF), our 10-50mm met-spar acts as a powerful fluxing agent. It rapidly reduces slag viscosity and lowers the melting temperature, accelerating the dissolution of lime ($text{CaO}$) and boosting the desulfurization and dephosphorization process.

2. Optimized Size for Furnace Charging

The 10-50mm lump size is precisely calibrated for industrial furnace charging systems. It minimizes dust loss during handling and charging, ensures even distribution within the melt, and prevents premature blowing out by furnace drafts.

3. Foundry and Ferroalloy Production

Perfect for iron foundries and ferroalloy smelting, this high-purity fluorite enhances ladle fluidity, reduces inclusions in the final metal matrix, and minimizes refractory wear compared to lower-grade fluxes.

• Storage: Store in a dry, well-ventilated area. Avoid cross-contamination with other minerals or chemicals.

• Global Shipping: Standard container loading (FCL) or bulk vessel shipments from major global ports with full compliance with custom clearance regulations.

Frequently Asked Questions (FAQ) 

Q: What is the main function of Met-spar 90% in steel manufacturing?

A: CaF2 90% Met-spar serves as a liquidus-lowering agent. It thins the slag layer, allowing quicker chemical reactions for the removal of sulfur and phosphorus, which directly improves the tensile strength and quality of the finished steel.

Q: Why is the 10-50mm size range critical for metallurgical fluorspar?

A: The 10-50mm fraction balances melting rate and material handling. Fines below 10mm often cause heavy dust and material loss in high-draft furnaces, while lumps larger than 50mm take too long to dissolve, delaying the smelting cycle.

Q: Can you supply low-sulfur, low-phosphorus fluorspar lumps?

A: Yes. Our metallurgical fluorspar is rigorously screened to maintain Sulfur under 0.1% and Phosphorus under 0.05%, preventing harmful element pickup in low-carbon or specialty steel grades.

Why Choose Us as Your Fluorspar Supplier?

• Stable Supply Chain: Direct access to major fluorite mining operations ensuring year-round, consistent volume capacity.

• Strict Quality Control: Every batch undergoes SGS/CCIC third-party inspection before shipment to verify $text{CaF}_2$ and impurity levels.

• Custom Sizing: While 10-50mm is standard, we can customize grain sizes (e.g., 0-10mm, 10-30mm) upon request.
