Contact UsVietnam's capital is at the heart of a booming industrial transformation — and refractory materials are a critical backbone of this growth.
Hanoi and its surrounding provinces host numerous steel mills, rolling plants, and ferroalloy producers. The demand for high-purity corundum bricks in electric arc furnaces (EAF), ladles, and tundishes has surged as Vietnamese steelmakers modernize their facilities to meet domestic infrastructure demands driven by rapid urbanization and construction growth across the Red River Delta region.
Vietnam is among Asia's top cement producers, and Hanoi's surrounding industrial zones include major cement clinker lines. Corundum and mullite refractory bricks are essential for rotary kilns, preheaters, and coolers. As Vietnam's cement industry expands capacity to serve Belt & Road infrastructure projects and domestic housing demands, the need for durable, heat-resistant refractory solutions continues to grow significantly.
The glass manufacturing sector in northern Vietnam, including facilities near Hanoi, relies heavily on high-alumina and corundum refractory bricks for furnace linings, regenerators, and forehearths. As Vietnamese glass producers upgrade to float glass and specialty glass production lines, the specification requirements for refractory materials have become increasingly stringent, favoring premium corundum solutions.
Vietnam's expanding energy sector, including thermal power plants and petrochemical refineries in the north, demands high-performance refractory linings for boilers, reformers, and cracking units. Corundum bricks' exceptional resistance to chemical attack and thermal shock makes them the preferred choice for these critical high-temperature applications in Hanoi's growing industrial corridor.
SK Refractory corundum bricks are engineered to perform in the most demanding industrial environments found across Hanoi and northern Vietnam.
High-purity corundum bricks provide exceptional wear resistance and thermal stability for EAF sidewalls and roofs in Hanoi's steel production facilities, extending campaign life and reducing maintenance downtime.
Vietnam's cement kilns operating at temperatures exceeding 1450°C demand refractory bricks with superior hot strength. Corundum bricks deliver consistent performance in the critical burning zone, reducing refractory replacement frequency.
Fused-cast corundum and alumina-based bricks are ideal for glass tank furnace crowns, sidewalls, and regenerator chambers in northern Vietnam's growing flat glass and container glass industries.
Corundum refractory bricks resist chemical erosion from hydrogen, sulfur compounds, and hydrocarbons at elevated temperatures — essential for reformers and cracking units in Vietnam's expanding refinery sector.
SK's corundum and high-alumina bricks are used in the combustion chambers and flue gas ducts of coal-fired and biomass power plants serving Hanoi's industrial zones, providing long-term thermal insulation and structural integrity.
Copper, aluminum, and zinc smelters in northern Vietnam rely on corundum bricks for furnace linings due to their excellent resistance to molten metal penetration and slag corrosion at high operating temperatures.
The Vietnamese refractory market is undergoing significant transformation, driven by industrial modernization, environmental regulations, and technological advancement.
Vietnam's refractory market is projected to grow at a CAGR exceeding 6% through 2030, driven by massive infrastructure investment, industrial zone expansion around Hanoi, and FDI inflows into manufacturing sectors requiring high-temperature processing equipment.
Vietnamese industrial facilities are increasingly adopting energy-efficient refractory solutions to meet stricter environmental regulations. Lightweight corundum and insulation bricks reduce heat loss, lower fuel consumption, and decrease CO₂ emissions — aligning with Vietnam's net-zero commitments.
As Vietnamese manufacturers upgrade to higher-efficiency furnace technologies, the demand for ultra-high purity corundum bricks (Al₂O₃ content >99%) is rising. SK Refractories' advanced sintering technology meets these increasingly stringent material specifications.
Geographic proximity and strong bilateral trade relations make China the preferred source for Vietnam's refractory imports. SK Refractories' established logistics network ensures rapid, cost-effective delivery to Hanoi and major Vietnamese industrial ports including Hai Phong.
SK Refractories employs advanced digital inspection systems, including automated dimensional checking and XRF chemical analysis, ensuring every batch of corundum bricks shipped to Hanoi meets precise technical specifications and international quality standards.
Rather than transactional sales, SK Refractories builds long-term technical partnerships with Hanoi-based industrial clients, providing furnace lining design consultation, installation guidance, and post-delivery technical support to maximize refractory service life.
