Refractory Fireclay Bottom Blocks
The Refractory Fireclay Bottom Blocks are manufactured from fireclay refractory composition containing Al2O3 between 30 and 45 percent by weight. The blocks achieve a refractoriness exceeding 1580 °C and are noted for strong resistance to hydrogen diffusion and alkali erosion. Production follows fine batching, forming, drying, controlled firing and subsequent cutting, grinding, milling and drilling to guarantee dimensional accuracy. The supplier states that each unit is inspected for appearance and size before packaging on wooden pallets or crates for export.
In the broader refractory market, bottom blocks of this type are commonly employed in blast furnaces, reheating furnaces and floating glass tin baths where thermal shock resistance is critical. Typical industry dimensions are 250 mm × 250 mm × 100 mm, although custom sizes can be requested. Standard density is around 2.0 t/m³ with a porosity of about 15 percent, providing a balance between strength and insulation. These blocks meet the usual ASTM C618 specifications for fireclay refractories, making them interchangeable with other globally sourced units.
Potential buyers include glass manufacturers, steel producers and any plant requiring a durable refractory lining for high‑temperature zones. The blocks are supplied in bulk, palletised for safe handling, and can be ordered to match specific furnace layouts. Because the listing does not disclose minimum order quantities, lead times or incoterms, importers should confirm those details directly with the supplier. Payment conditions and shipping terms are also subject to negotiation prior to contract finalisation.

Sourcing Refractory Fireclay Bottom Blocks from Zhengzhou Smien Refractories Co., Ltd. - China Import Guide
Before placing an order, importers should ask for a full chemical analysis report and a refractoriness test certificate to confirm the Al2O3 range and the >1580 °C rating. Verifying these documents helps ensure the product meets the thermal performance required for the intended furnace environment.
Logistics details such as Incoterms (FOB, CIF, etc.), lead‑time estimates and container loading plans need to be agreed with the supplier. Because the listing does not disclose these terms, request a detailed shipping quotation and confirm the agreed delivery schedule. Payment terms, whether letter of credit or advance payment, should also be clarified in advance.
Arrange a third‑party inspection at the factory or upon arrival to check dimensions, surface finish and mechanical strength. Request a sample batch for pilot testing if possible, and ensure that the inspection report includes density, porosity and compressive strength measurements. Proper documentation will reduce the risk of receiving non‑conforming refractory material.
