Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The casting material supplied by Gongyi City Hong The Refractory Material Co., Ltd. is a type of unshaped refractory castable composed of refractory aggregates and hydraulic or chemical binders. It is designed for application by pouring or vibration, forming monolithic linings in industrial furnaces, kilns, and incinerators. The material is classified by aggregate type, binder system, and porosity, with common variants including high-alumina, clay, and siliceous castables.
The aggregates used range from high-alumina (Al2O3 ≥45%) to siliceous (SiO2 ≥85%) and include special materials such as zircon, spinel, or alumina hollow balls for insulation. Binders include calcium aluminate cement, water glass, or phosphate compounds, each determining the curing mechanism. Dense castables have porosity under 20%, while insulating types exceed 45% porosity and are used for thermal barrier layers. The material requires precise water addition during mixing - typically 5% to 9% by weight - to achieve optimal flow and strength.
This material is purchased by steel mills, cement plants, and glass manufacturers for furnace linings, burner blocks, and ladle linings. Buyers typically order in bulk quantities of 500 kg to 5 metric tons, packed in multi-layer paper bags with moisture barrier lining. Delivery is FOB Zhengzhou or CIF destination port. Lead times are 15 to 25 days after order confirmation. Technical data sheets and firing schedules must be provided with each shipment.
| Material type | Unshaped refractory castable, hydraulic or chemical bonded |
| Aggregate type | High-alumina (Al2O3 ≥45%), clay (Al2O3 30% - 45%), siliceous (SiO2 ≥85%), or special (zircon, spinel, alumina hollow balls) |

| Water content for mixing | 5% to 9% by weight, depending on binder and aggregate |
| Maximum service temperature | Up to 1700°C for high-alumina castables, 1350°C for clay-based, 1600°C for siliceous |
| Cold crushing strength | Typical range: 20 MPa to 80 MPa after curing and firing |
| Apparent porosity after firing | Dense: 10% - 18%; insulating: 45% - 75%, standard per ISO 5017 |
| Thermal expansion coefficient | Typical: 0.8 - 1.4 ×10⁻⁶/°C for high-alumina castables, varies with aggregate |
| Packaging | 25 kg multi-layer paper bags with polyethylene inner liner, palletized for bulk shipment |

Before ordering, confirm the aggregate type, binder system, and porosity class of the casting material. Request the chemical analysis report for each batch, including Al2O3, SiO2, Fe2O3, and CaO content. Verify that the material meets the required service temperature and thermal shock resistance for your furnace. Do not accept material without a technical data sheet and firing instructions.
Confirm the Incoterms - FOB Zhengzhou is standard. Lead time is typically 15 to 25 days after deposit, depending on batch size and binder formulation. Packaging must be moisture-proof multi-layer paper bags, sealed and palletized. Payment terms are commonly 50% advance, 50% against bill of lading. Ask for a certificate of origin and safety data sheet for customs clearance.
Inspect each bag for damage, moisture, or clumping. Weigh a sample to confirm net weight and check for uniformity. Test a small batch for flowability and curing time before full use. Request a third-party inspection report for cold crushing strength and apparent porosity if the order exceeds 2 metric tons. Ensure the supplier provides batch traceability and firing recommendations with every shipment.
