On May 6, 2025, Rongsheng Refractory received a $1500 advance payment from a new customer in Colombia for an order of Corundum Spinel Ramming Mass. This marks another successful step in our continued global expansion and underscores the growing demand for reliable monolithic refractory materials in the Latin American steel and foundry industries.

Customer Background

The client is a mid-sized ferrous alloy producer based in Colombia, operating several induction furnaces for high-temperature smelting. They contacted us through our company website after searching for a more durable and thermally stable ramming material. Their team was specifically looking for a product that could:

  • Withstand continuous exposure to molten metal and slag,

  • Maintain lining integrity under extreme thermal cycling,

  • Extend the operational lifespan of their furnace lining.

After technical discussions and product comparisons, they selected our Corundum Spinel Ramming Mass as the most suitable solution.

What Makes Our Corundum Spinel Ramming Mass Stand Out?

Rongsheng’s Corundum Spinel Ramming Mass is engineered using high-purity fused alumina, synthetic magnesium aluminate spinel, and selected binding agents. This combination gives it excellent thermochemical stability and mechanical strength.

Key Features:

  • 🔥 High Working Temperature: Resistant to temperatures exceeding 1750°C.

  • 🛡️ Superior Slag Resistance: The spinel component provides exceptional resistance to chemical corrosion and erosion.

  • ⚙️ Good Volume Stability: Prevents cracks or spalling during heating and cooling cycles.

  • 🧱 Strong Sintering Performance: Develops solid bonding at high temperatures to form a dense, durable lining.

  • 🧪 Customizable Formula: We offer tailored formulations depending on customer furnace conditions and lining thickness requirements.

Order Details and Delivery

The Colombian customer started with a trial order, showing strong interest after receiving technical documentation and material samples. Within two weeks, the following steps were completed:

  • Sample testing and approval by the customer’s quality control team

  • Contract signed and advance payment of $1,500 received on May 6

  • Product prepared, packed in moisture-proof bags, and scheduled for export by container freight

This client appreciated not only the quality and technical performance of the product but also our efficient response, professional service, and clear documentation.

Long-Term Cooperation Potential

The customer plans to monitor performance over the next three production cycles. If results meet their expectations, they intend to:

  • Convert to full furnace linings with our ramming mass

  • Explore additional Rongsheng products such as Magnesia Carbon Bricks and Refractory Castables

  • Recommend Rongsheng as a trusted refractory supplier to their partner factories in Latin America
