The Magnesia Alumina Spinel Brick for Ladle is a refractory brick formulated from fused MgAl2O4 spinel and a MgO‑Al2O3 composite. It is intended for secondary refining ladle linings in steelmaking and can also line RH degassers and tundish sections. The supplier lists the material as high‑purity spinel with bulk density and colour consistency suitable for demanding thermal cycles. The product description highlights superior thermal‑shock resistance, slag‑corrosion resistance and high‑temperature strength compared with conventional doloma bricks.
The brick’s composition combines magnesia and alumina in a spinel crystal lattice, giving it a typical bulk density of 3.3 g/cm³ and a typical compressive strength of 30 MPa at 1700 °C. Industry standards classify such spinel bricks under ASTM C880 for high‑temperature refractories, and they are often supplied in dimensions of 250 × 125 × 76 mm. Typical tolerances on length and width are ±2 mm, while thickness tolerance is ±1 mm. These parameters allow reliable installation in ladle furnaces where dimensional stability under repeated thermal cycling is critical.
Primary buyers include steel producers, ladle furnace operators and foundries that require long service life and reduced maintenance intervals. The supplier notes that the bricks are suitable for import‑export trade and can be packed in standard 1 m³ pallets for ocean freight. Prospective importers should confirm the exact lot size, Incoterms and payment conditions directly with the supplier before placing an order.

Before placing an order, verify the supplier’s business licence, export registration and any relevant refractory material certifications. Request a recent factory audit report or third‑party inspection certificate to confirm production quality and compliance with international standards.
Discuss logistics early: confirm the preferred Incoterms (e.g., FOB Xinmi Port or CIF Shanghai), typical lead time for production and shipping, and acceptable payment terms such as a letter of credit or T/T in advance. Ensure that the supplier can provide a detailed packing list and bill of lading that matches the order specifications.
Arrange for pre‑shipment inspection focusing on dimensions, bulk density and compressive strength. Ask for a full test report covering chemical composition, refractoriness and any required quality certificates. Having these documents before acceptance helps minimise the risk of non‑conforming bricks arriving at the plant.
