Compared to alumina silica fire brick, this silica firebrick maintains structural stability longer, reducing shutdowns for repairs. For preheating zone linings, it ensures consistent heat retention and extends service life to 18-24 months, eliminating “thermal shock-induced failure” worries for users.
Tertiary air ducts in cement plants suffer from 1000-1300℃ high temperatures plus abrasive dust (from raw materials), which wear down regular refractories quickly. Highland’s high-density silica fire brick is tailored for this: its apparent porosity ≤16% and cold compressive strength ≥28MPa resist dust scouring, while refractoriness 1690-1730℃ handles sustained heat. Unlike common alumina silica fire brick that erodes in 6-8 months, this silica firebrick lasts 12-15 months. It fits duct bends and straight sections seamlessly, solving “fast wear” pain points and keeping air flow stable for cement production.
Fifth-stage preheaters in cement lines face acidic dust from raw material decomposition and 900-1100℃ heat—ordinary bricks corrode easily, causing material leakage. Highland’s acid-resistant silica fire brick addresses this: its high SiO₂ content (≥94%) forms a barrier against acidic media, outperforming alumina silica fire brick that succumbs to corrosion. This silica firebrick also has low water absorption (≤2%), preventing dust adhesion and blockages. For preheater linings, it ensures no leakage or clogging, extending maintenance intervals by 50% and solving “corrosion-induced downtime” for users.
Transition zones of cement rotary kilns endure sudden temperature shifts (1200-1500℃) and abrasive clinker impact ordinary bricks deform or break, disrupting production. Highland’s high-strength silica fire brick is ideal here: its creep rate ≤0.5% at 1600℃×50h resists deformation, and cold compressive strength ≥25MPa withstands clinker scouring. Compared to alumina silica fire brick, this silica firebrick adapts better to the transition zone’s harsh conditions, lasting 20-24 months.

To ease foreign buyers’ (e.g., preheater, tertiary air duct, lime kiln users) worries about opaque processes and unstable quality, Highland Refractory follows a strict workflow for Silicon Brick. We first inspect high-purity silica raw materials, testing SiO₂ content (≥93%, critical for acid resistance) and impurity levels—stricter than standards for alumina silica brick—to lay a solid foundation for silica refractory brick. Next, we use 800-ton precision hydraulic presses to mold the mixture, ensuring uniform density; then sinter it at 1350-1450℃ to enhance heat resistance and reduce creep, a key advantage over alumina silica refractory brick.
Every batch undergoes rigorous testing (refractoriness 1690-1730℃, cold compressive strength ≥25MPa). Guided by ISO 9001:2015, we monitor each step (from raw material intake to final inspection) and provide detailed test reports. This “strict production + full-process monitoring” ensures consistent quality across all silica refractory brick, fully eliminating importers’ doubts.
Fifth-stage preheater users in cement plants face a major pain: acidic dust (from raw material decomposition) and 900-1100℃ heat corrode ordinary refractories quickly, leading to frequent brick replacement and material leakage. Highland’s silica fire brick addresses this perfectly its SiO₂ content ≥93% (up to 96% for premium grades) forms a dense, acid-resistant barrier that outperforms alumina silica fire brick, which often succumbs to corrosion in 6-8 months. This silica firebrick also has low water absorption (≤2%), preventing dust adhesion and blockages. For preheater linings, it maintains integrity for 18-24 months, eliminating “corrosion-induced downtime” and reducing maintenance costs significantly.
Lime kiln discharge chute operators struggle with mismatched bricks standard silica firebrick can’t fit the chute’s irregular angles and narrow gaps, forcing costly equipment modifications or risky on-site cutting. Highland solves this with fully customized silica fire brick: we adjust sizes (tolerance ≤±1mm), shapes (wedge shaped, curved, or notched), and even SiO₂ content based on your chute’s structural drawings. Unlike rigid alumina silica fire brick, our tailored silica firebrick integrates seamlessly into the chute’s unique design, avoiding modifications and ensuring smooth material flow. This “made-to-fit” advantage saves you time and money while preventing brick damage from poor alignment.
Tertiary air duct users in cement production deal with frequent brick failures 1000-1300℃ heat plus abrasive dust wear down ordinary refractories in 8-10 months, causing unplanned shutdowns and high procurement costs. Highland’s silica fire brick changes this via advanced 1350-1450℃ sintering technology, which boosts its cold compressive strength to ≥25MPa and reduces creep rate (≤0.5% at 1600℃×50h). Compared to alumina silica fire brick, its service life extends to 15-18 months halving replacement frequency. This “long-life” benefit slashes annual refractory costs by 30% and minimizes production disruptions, making it a cost-effective choice for air duct linings.
Preheating zone users (in cement/glass kilns) face temperature fluctuations (800-1200℃) that cause ordinary bricks to crack or peel, threatening heat retention and kiln efficiency. Highland’s silica fire brick excels here: its refractoriness reaches 1690-1730℃, easily enduring peak preheating temperatures, and its low thermal expansion coefficient (≤0.5% at 1000℃) resists thermal shock better than alumina silica fire brick. This silica firebrick maintains structural stability even after 50+ heat cycles, avoiding cracks that lead to heat loss. For preheating zone linings, it ensures consistent thermal performance and extends service life, solving “temperature-swing damage” worries and keeping your kiln running smoothly.
