Zhengzhou Huachen Refractory Co., Ltd. supplies fused cast blocks and bricks made from an alumina‑zirconia‑silica (AZS) composition in China. The product family includes three grades - AZS‑33#, AZS‑36# and AZS‑41# - each with increasing zirconia content for enhanced corrosion resistance. The supplier describes the blocks as having very good glass‑melting resistance and low bubble formation, making them suitable for demanding furnace environments. These AZS bricks are produced by electric fusion casting, resulting in a dense, low‑porosity structure.
In the refractory market, AZS‑33# typically contains about 33 % zirconia, AZS‑36# around 36 % and AZS‑41# roughly 41 % zirconia, with the remainder primarily alumina and silica; this gradient improves erosion resistance across furnace zones. Standard compressive strength for these grades ranges from 130 MPa for 33# to 150 MPa for 41#, while thermal shock resistance commonly exceeds a ΔT of 1200 °C. Block dimensions are usually 100 × 100 × 100 mm with a tolerance of ±1 mm, and they are shipped in palletised crates that can be customized to fit specific lining designs. These typical parameters align with industry practice for high‑temperature glass and steel furnace linings.
Typical users include glass manufacturers, steel ladle producers and other high‑temperature process plants that require long‑lasting refractory linings. Importers often order the bricks in bulk, packed on standard pallets for container loading. Buyers should confirm the minimum order quantity, lead‑time and preferred Incoterm directly with Zhengzhou Huachen before finalising the purchase.

Zhengzhou Huachen Refractory Co., Ltd. is located at 1899th Zhongzhou Road, Guancheng District, Zhengzhou, Henan Province, China, postal code 450000. The company holds a harbor trust tier, indicating verified registration details on the platform. Its response rate is recorded as 0 %, with no average response time, suggesting limited recent interaction with inquiries. The supplier publicly lists its address but provides no additional corporate background in the listing.
The firm advertises fused cast AZS bricks in three grades and highlights their erosion resistance, low bubble formation and thermal shock performance. No data is supplied regarding production capacity, certifications, minimum order quantities or lead‑time, so buyers should request these specifics directly. Zhengzhou Huachen does not list client references or export records, underscoring the importance of independent verification before contract award.
Fused Cast AZS bricks are premium-grade refractory blocks manufactured through electric fusion casting, available in AZS-33#, AZS-36#, and AZS-41# grades with progressively higher zirconia content for superior corrosion and erosion resistance. These blocks are widely applied in glass melting furnaces, forehearths, and feeder channels in the glass industry, as well as in steel ladles and other high-temperature metallurgical processes requiring long service life under severe thermal stress. As a high-value industrial refractory export product, AZS blocks are traded globally in standard palletized packaging with customizable dimensions to meet specific furnace lining specifications.

Sourcing Fused Cast Blocks/Bricks from Zhengzhou Huachen Refractory Co., Ltd. - China Import Guide
When ordering AZS bricks from Zhengzhou Huachen, first confirm the company’s business licence and request a material certification that details the exact alumina, zirconia and silica percentages for the chosen grade. Compare the supplied composition data with the typical values listed here to ensure consistency. Because the platform shows a zero response rate, ask for recent factory photographs or third‑party audit reports to validate production capability before committing to purchase.
Agree on an Incoterm that matches your supply chain, such as FOB Zhengzhou or CIF Shanghai, and verify that the supplier can load the palletised crates onto a container without damaging the blocks. Since lead‑time is not disclosed, request a detailed production schedule and confirm whether the supplier can meet your required delivery date. Payment is often
