Fused Silica Precast Block
The fused silica precast block is a refractory element manufactured from high‑purity fused silica with a SiO2 content exceeding 99.5 %. It is cast in a brick‑shaped form to allow rapid hot‑repair of coke oven linings and glass‑melting furnace chambers. The blocks exhibit near‑zero thermal expansion and excellent thermal‑shock resistance, characteristics essential for maintaining structural integrity during rapid temperature changes. Luoyang Maile Refractory produces these blocks at its Henan facility and ships them from China.
Fused silica is a standard material in the refractory industry, valued for its low expansion coefficient and ability to withstand temperatures above 1 600 °C. Typical grades are classified by purity, with the >99.5 % grade used for critical repair applications where dimensional stability is required. The blocks are supplied in standard dimensions that facilitate easy handling and installation, while custom sizes can be requested from the supplier’s technical team. The manufacturing process follows ISO 9001:2008 quality management procedures, ensuring consistent material properties.
Primary users include steel‑plant maintenance contractors, glass‑furnace operators and non‑ferrous metal processors who need reliable hot‑repair solutions. Buyers typically request bulk shipments packed in wooden crates, with the option to negotiate FOB or CIF terms based on destination port. Because the listing does not disclose a minimum order quantity, lead time or exact incoterm, importers should confirm these details directly with the supplier before placing an order. Payment terms are usually negotiated on a case‑by‑case basis, often involving a letter of credit or advance payment.

| Thermal shock resistance | Excellent (typical for high‑purity fused silica) |
| Density | Typical 2.2 g/cm³ |
| Compressive strength | Typical 150 MPa |
| Standard dimensions | Typical 500 mm × 300 mm × 200 mm |

Luoyang Maile Refractory Co., Ltd. is located at No.33 Longhua Avenue, Mengjin, Luoyang, Henan 471133, China. The company is listed in the harbour trust tier, although its response rate is currently 0 %. All technical and quality‑control staff were recruited from Sinosteel Refractories, bringing more than two decades of silica‑refractory experience. The firm holds an ISO 9001:2008 certification that governs its production processes.
The supplier specialises in a full range of silica‑based refractories, including fused silica bricks, precast blocks, mortars and ramming mixes for hot‑repair of coke ovens and glass furnaces. Its product catalogue stresses low thermal expansion and the ability to minimise flue‑gas leakage during service. While the company does not publish specific MOQ or lead‑time figures, it invites customers to discuss project requirements directly with its sales team. The focus on technical expertise rather than volume positioning makes it a niche source for high‑purity silica elements.
Fused silica precast blocks are high-performance refractory shapes designed for hot repair of coke ovens and glass melting furnaces. These blocks offer exceptional thermal shock resistance and low thermal expansion due to their high-purity fused silica composition, typically exceeding 99.5% SiO2. Widely used in steel, glass, and non-ferrous metal industries, fused silica precast elements are increasingly in demand for kiln maintenance and furnace rebuilding projects, making them a key import-export commodity in the global refractory trade.

Sourcing Fused Silica Precast Block from Luoyang Maile Refractory Co., Ltd. - China Import Guide
Before placing an order, importers should request the latest mill test report that details SiO2 purity, thermal expansion data and compressive strength. Verify the block dimensions and weight against the specification sheet to avoid mismatches during installation. Confirm the supplier’s production capacity and any required tooling for custom sizes, as these factors influence lead time. Ensure that the payment method and credit terms are clearly documented in the purchase contract.
Shipping is normally arranged from the nearest Chinese port, with FOB or CIF options depending on the buyer’s preference. Typical transit time to European or North American ports ranges from 30 to 45 days, but exact lead time must be confirmed with the supplier. Importers should clarify the Incoterm, container size, and whether the blocks will be palletised or bulk‑loaded. Payment is commonly secured via a confirmed irrevocable letter of credit, though advance payment may be negotiated for first‑time orders.
Upon arrival, a third‑party inspection should verify dimensions, weight and surface condition against the supplied certificates. A random sample can be subjected to a compressive strength test to confirm compliance with the 150 MPa specification. Retain the ISO 9001:2008 certification and mill test report as part of the quality documentation for future audits. Any deviation should be reported to the supplier immediately to arrange replacement or corrective action.
