Buy & Import Fused Cast Azs Block from Henan Reftech Industrial Co., Ltd. - Wholesale Supply

The RTK‑AZS33 fused cast block is a refractory component designed to minimise contamination from molten glass, reducing the formation of stones, bubbles and exudation of the matrix glass. It is manufactured by Henan Reftech Industrial Co., Ltd. in Xinmi, Henan Province, China and carries the RTK‑AZS33 grade designation. The block’s composition and dense microstructure give it a strong resistance to glass ingress, making it suitable for demanding furnace environments.

Typical AZS bricks contain about 33 % alumina, 5 % zirconia and the remainder silica, giving a bulk density near 3.5 g/cm³ and a compressive strength of at least 200 MPa. The porosity is usually below 5 %, which contributes to low gas permeability and excellent thermal‑shock resistance of roughly 150 °C temperature differentials. These industry‑standard figures are recognised across glass‑melting and steel‑making refractory applications.

Common installations include the super‑structure of melting tanks, sidewalls, paving blocks and fore‑hearth sections of glass furnaces. Buyers such as glass container manufacturers and steel foundries source the blocks in bulk pallets, with packaging typically on wooden crates. Because the listing does not disclose minimum order quantities, lead‑times or Incoterms, interested importers should confirm those details directly with the supplier before placing an order.

Frequently Asked Questions About Fused Cast Azs Block from Henan Reftech Industrial Co., Ltd.
The RTK‑AZS33 designation corresponds to a typical alumina content of about 33 % Al2O3. Buyers should request the supplier’s material analysis report to confirm the exact figure for a given batch.

Sourcing Fused Cast Azs Block from Henan Reftech Industrial Co., Ltd. - China Import Guide

Before placing an order, verify the exact chemical composition, grade designation and any test certificates that the supplier can supply. Request a mill‑test report that details alumina, zirconia and silica percentages, as well as density and compressive strength values. This information helps confirm that the block meets the performance requirements of your furnace design.

Discuss logistics early: clarify the preferred Incoterm (FOB, CIF or DDP), expected lead‑time from production to shipment, and the method of payment. Because the supplier’s response rate is currently zero, it is advisable to establish a clear line of communication through a verified contact and to obtain written confirmation of shipping schedules and payment milestones.

Arrange for third‑party inspection either before loading or at the destination port to verify dimensions, surface quality and absence of cracks. Request documentation such as a material safety data sheet, a refractory index certificate and a final inspection report. These steps reduce the risk of receiving non‑conforming material and support smooth customs clearance.
