The Graphite Carbon Refractory Brick offered by Simzone is a premium-grade refractory designed for high-temperature metal processing. It is composed of a graphite carbon composite containing 97.72% carbon and 2.28% ash, giving a bulk density of 1.555 Mg/m3. Laboratory testing records a cold crushing strength of 31.13 MPa and an apparent porosity of 16.53%. The bricks are supplied in dimensions of 1 mm-2 mm width and 0.6 m-0.7 m depth, and are manufactured in South Korea.
Graphite carbon composites of this purity are classified as high-performance refractory material, comparable to industry grades such as GCB-97 used in steelmaking furnaces. The low ash content reduces slag formation, while the high bulk density enhances thermal conductivity and structural stability during rapid temperature cycles. Typical refractory specifications for similar products call for carbon content above 95% and crushing strength above 30 MPa, placing this brick within the upper tier of performance. Such characteristics are essential for maintaining lining integrity in continuous casting and electric arc furnace operations.
These bricks are suitable for lining blast furnaces, steelmaking converters and electric arc furnaces, where they provide resistance to thermal shock and chemical erosion. Primary buyers include foundries, steel producers and large-scale metal processing plants that require durable refractory linings. Simzone lists the product without disclosed minimum order quantity, lead time or incoterms, so interested importers should request bulk pricing, shipping terms and payment conditions directly from the supplier. Confirmation of certification and test reports is advisable before finalising any contract.

Simzone is a supplier based in Seoul, South Korea, registered at Simzone Bldg, #56, 37-Gil, Bangbae-Ro Seocho-Gu, postal code 06557. The company is classified in the harbor trust tier on the platform, indicating a verified business registration, although the listed response rate is currently 0% and no average response time is recorded. The address places the operation within the capital’s industrial district, providing proximity to major ports and logistics hubs.
The current listing focuses on the Graphite Carbon Refractory Brick and provides detailed material specifications, but it does not include information on production capacity, certifications such as ISO 9001, or previous export experience. Prospective buyers should therefore seek additional confirmation of quality management systems and past project references directly from Simzone.

Before placing an order with Simzone, importers should verify the company’s business registration and request the latest mill test report that confirms carbon and ash percentages, bulk density and crushing strength. It is also prudent to ask for a certificate of conformity to relevant refractory standards such as ASTM C133. Any deviation from the listed specifications should be clarified in writing prior to contract signing.
Because the listing does not disclose lead time, incoterms or payment conditions, buyers need to discuss these details directly with Simzone. Typical arrangements for Korean refractory exporters involve FOB Busan or CIF Shanghai, but the exact port and schedule must be agreed upon. Importers should also confirm whether the supplier can accommodate containerised shipments of the 0.6 m-0.7 m bricks or prefers bulk freight.
For critical applications, a third-party inspection at the factory or upon arrival is advisable to verify dimensions, porosity and mechanical strength. Requesting a full set of documentation - including the test report, material safety data sheet and any export certificates - will help ensure compliance with the buyer’s quality system. Where possible, arrange for a pre‑shipment sample to be evaluated against the stated specifications.
