Real-World Applications

Our refractories in action across global industries.

Glass Kiln Heat Storage Pool

Customers use our magnesia-chrome bricks to construct glass kiln heat storage pools. These bricks demonstrate excellent resistance to alkali steam and alkaline slag, ensuring long-term structural integrity and reduced maintenance.

Corrosion-resistant in high-alkali environments

Copper (Silver) Converter Lining

The copper and silver converter lining is primarily constructed using our magnesia-chrome fire bricks. These bricks exhibit outstanding resistance to thermal cycling and chemical attack, critical for continuous operation.

Superior thermal shock resistance

Long-Term Supply with Yukun Iron & Steel

Liaoning Wancheng has signed a long-term supply contract with Yukun Iron and Steel Group Co., Ltd. for lime kiln bricks. Our partnership is built on trust, quality, and shared values of honest management and customer-first principles.

Strategic domestic partnership

Collaboration with Japanese Clients

In October 2023, Japanese clients visited our facility to discuss cooperation on light-burned magnesia powder. The visit strengthened mutual understanding of product quality, business philosophy, and future market opportunities for 2024 and beyond.

Frequently Asked Questions

What is the difference between fused and sintered magnesia?

Fused magnesia is produced by melting raw magnesite at over 2800°C, resulting in large crystals with high purity and thermal stability. Sintered magnesia is made by high-temperature calcination (1600–1800°C), offering good performance at a lower cost.

Can you customize refractory brick dimensions?

Yes, we offer custom shapes, sizes, and formulations based on customer specifications and furnace design requirements.

What certifications do your products have?

Our production follows international quality standards. We maintain strict in-house testing and documentation for every batch. Specific certifications available upon request.

How do you ensure consistent product quality?

We control the entire process—from raw ore selection to final inspection—using advanced testing equipment in our company testing center.
