Silica Brick for Coke Oven
The Silica Brick for Coke Oven supplied by Cunse Refractory is a high‑purity SiO₂ refractory brick designed for demanding high‑temperature environments. According to the supplier data the brick contains 94.5 % silica, 1.0 % Al₂O₃, 1.0 % Fe₂O₃ and 2.5 % CaO, with an apparent porosity of 22‑24 % and a true density of 2.32‑2.33 g/cm³. Mechanical strength is indicated by a cold crushing strength of 40 MPa for sole and wall positions, and the product tolerates refractoriness under a 0.2 MPa load of 1650‑1660 °C.
In the refractory industry, silica bricks of this composition are typical for coke oven chambers because the high tridymite content provides good thermal conductivity and resistance to acid slag. Standard brick dimensions are often 250 mm × 125 mm × 65 mm, and a typical thermal expansion coefficient is around 1.28 × 10⁻⁶ /K, matching the values supplied for this product. The brick’s residual quartz content is limited to 0‑1 % to minimise swelling, which aligns with usual specifications for coke‑oven refractory linings.
These bricks are primarily purchased by steel manufacturers, coke‑plant operators and refractory contractors constructing coke oven chambers, combustion chamber partitions and regenerative furnace components. The supplier indicates the product is packaged for safe international transit, but does not disclose specific MOQ, lead‑time or payment terms, so buyers should request those details. Compliance with relevant industry standards should be confirmed through certificates before shipment.

Sourcing Silica Brick for Coke Oven from Cunse Refractory - China Import Guide
Prior to ordering, importers should verify the exact chemical composition, especially the SiO₂ purity and impurity levels, to ensure compatibility with the coke‑oven process. Request a material safety data sheet and a recent batch analysis report. Confirm that the brick dimensions and thermal expansion coefficient match the design specifications of the furnace.
Discuss shipping arrangements with the supplier, specifying the preferred Incoterm (FOB or CIF) and the departure port in China. Because the supplier’s response rate is currently zero, agree on a clear lead‑time schedule and a secure payment method such as T/T in advance or a documentary letter of credit. Clarify packaging details, such as wooden crates or steel pallets, to protect the bricks during transit.
Arrange for a third‑party pre‑shipment inspection to check dimensional tolerances, porosity and cold crushing strength. Obtain a certificate of conformity and a test report confirming refractoriness under load. Maintaining these quality documents will streamline customs clearance and assure that the bricks meet the performance requirements of the coke‑oven installation.
