Refractory Sintering
The product offered is a sintered refractory brick composed of a clay‑alumina composite, designed for use in high‑temperature processes such as steelmaking, cement production and glass furnace operations. The supplier specifies that the bricks exhibit superior thermal shock resistance, a high hot modulus of rupture and a low permanent linear change after heating, attributes that are essential for maintaining structural integrity under rapid temperature fluctuations.
Sintered refractory bricks are produced by compacting a powdered blend of alumina‑rich clay and then firing at temperatures above 1500 °C, resulting in a dense, low‑porosity stone. In the industry, typical density values range from 2.8 to 3.2 g/cm³ and porosity is kept below 5 % to minimise gas penetration. Standard grades achieve compressive strengths of 30 - 45 MPa and can tolerate temperature jumps of up to 150 °C without cracking.
These bricks are commonly installed in blast furnace linings, ladle linings and rotary kiln interiors, where manufacturers require reliable performance and long service life. Importers targeting large‑scale steel plants, cement factories or glass producers usually order in bulk metric‑tonne shipments, with export packaging consisting of palletised bulk bags. Trade terms, incoterms and payment conditions should be negotiated directly with the supplier before confirming the order.

Sourcing Refractory Sintering from Zhengzhou Sunrise Refractory Co., Ltd. - China Import Guide
Before placing an order, verify that the supplier can provide a material test report confirming composition, density and strength values for the specific batch. Request a certificate of conformity to relevant standards such as ISO 9001 or EN‑12525, and ask for a sample for laboratory analysis if possible.
Discuss logistics early: confirm the preferred incoterm, whether the shipment will be FOB Zhengzhou or CIF to your destination port, and clarify the expected lead time for production and loading. Payment methods commonly include a confirmed irrevocable letter of credit or documentary collection; ensure that the supplier agrees to the terms before finalising the contract.
Arrange for third‑party inspection at the factory or prior to loading, focusing on dimensional tolerances, porosity and strength testing. Obtain the full set of documentation, including the test report, certificate of origin and packing list, to streamline customs clearance and guarantee product quality upon arrival.
