buyer's fifth product:Anchor brick

2026-02-03

I. Lessons Learned from Our Company's Global Construction Experience

1. Global Project Coverage

International Projects: Iran ZISCO 2.5 million-ton pelletizing project, India GSL 1.2 million-ton pelletizing project, Malaysia Maanshan Iron & Steel tundish project, etc.

Domestic Projects: Baosteel 5 million-ton pelletizing project, Handan Iron & Steel 2 million-ton pelletizing project, and over 140 rotary kiln systems.

These cases demonstrate our company's ability to apply anchoring bricks under various working conditions, from steel metallurgy to building materials and chemicals, covering complex conditions such as high temperature, corrosion, and frequent start-ups and shutdowns.

2. Technological Innovation Advantages

By 2025, we obtained professional technology for "an anchoring brick hanging device," which, through elastic buffer components and adjustable spacing design, avoids anchoring bricks from breaking due to excessive stress, extending the service life of the top cast-in-place structure.

We possess a Refractory Materials Engineering Technology Research Center, equipped with advanced physical testing, chemical analysis, and R&D equipment.

Second: Core strategies for procuring high-performance, cost-effective anchoring bricks

Operating conditions	Temperature range	Recommended materials	Core Features
Medium-temperature operating conditions (heating furnace, shuttle kiln)	1200-1500℃	High-alumina anchoring bricks (Al₂O₃≥55%)	The linear expansion rate after reheating at 1500℃ is only 0.05%, demonstrating strong resistance to high-temperature deformation.
High-temperature operating conditions (glass melting furnace, high-temperature calcining furnace)	>1500℃	Corundum or mullite anchoring bricks	Excellent high-temperature resistance, preventing the brick from softening and cracking.
Corrosive conditions (chemical reactors, steel soaking furnaces)	1000-1600℃	Anchor bricks containing zircon	It has strong resistance to chemical corrosion and reduces peeling.
Frequent start-stop operation (intermittent heating furnace)	800-1400℃	High-alumina anchor bricks	It exhibits good thermal shock resistance, showing no cracks or peeling after undergoing a 1100℃ water-cooling cycle test.

2. Key Performance Indicator Control

Bulk Density: The bulk density of high-quality anchor bricks must be ≥2.34g/cm³. Higher density results in stronger resistance to erosion and corrosion.

Compressive Strength: Hanging bricks for furnace roofs must have a compressive strength ≥50MPa to ensure load-bearing stability.

Dimensional Accuracy: Length, width, and height errors must be controlled within ±1mm; hole diameter and hole position deviations must not exceed 0.5mm.

Thermal Shock Stability: After a 1100℃ water-cooling cycle test, the bricks should show no cracks or peeling.

3. Cost-Effectiveness Optimization Strategy

Avoid Over-Design: Select appropriate materials based on actual working conditions, avoiding blindly pursuing high-end materials.

For example: For working conditions below 1300℃, ordinary high-alumina bricks (Al₂O₃ 48%-65%) are sufficient; there is no need to use high-purity high-alumina bricks (Al₂O₃ 65%-75%).

Bulk Purchasing Advantages: Chinese manufacturers typically offer tiered pricing, with lower unit prices for larger purchase quantities.

Customization Services: Chinese manufacturers support custom-made anchor bricks of special shapes and sizes, avoiding waste.

For example, curved furnace bodies can be customized with curved anchor bricks, avoiding uneven stress on the bricks caused by forced splicing.

4. Advantages of Overseas Procurement of Chinese Anchoring Bricks

Cost Advantage: The price of Chinese anchoring bricks is only 1/3 to 1/2 of that of European and American products.
Supply Chain Advantage: China's building materials industry cluster is mature and has a fast response time, which can meet the needs of short-cycle, large-volume procurement.
Technological Strength: Chinese companies possess many professional technologies in the field of anchoring bricks, such as our company's buffer hanging device.
Logistics Convenience: Sea freight from China to Southeast Asia, the Middle East, and other regions has a short transit time (approximately 30 days) and low cost.

III. Procurement Recommendations Based on Our Company's Case Studies

Steel Industry: Referring to the Handan Iron and Steel Group's 2 million-ton pelletizing project, select high-alumina anchoring bricks to ensure stable operation at high temperatures of 1200-1500℃.

Building Materials Industry: Referring to Baosteel's 5 million-ton pelletizing project, select anchoring bricks with good thermal shock resistance to adapt to frequent temperature rise and fall conditions.

Chemical Industry: Referring to Iran's ZISCO... A 2.5 million-ton pelletizing project case study: Zircon-containing anchoring bricks with strong corrosion resistance were selected to cope with acidic gas corrosion.

Special working conditions: If suspended installation is required, Hongda Furnace Industry's professional elastic buffer suspension device can be used to reduce stress concentration.

IV. Procurement Considerations

Sample Testing: Before bulk purchases, be sure to request samples from the manufacturer for high-temperature testing and performance testing.

Contract Terms: Clearly define quality standards, delivery time, and after-sales service terms, especially for overseas purchases regarding logistics and customs clearance.

Technical Support: Choose manufacturers that can provide on-site construction guidance and technical services, such as Hongda Furnace Industry's professional after-sales service team.

Certification Requirements: Understand the certification standards of the target market (such as EU CE certification) to ensure that products comply with local regulations.
