Direct-bonded Magnesia Chrome Bricks
Direct-bonded magnesia chrome bricks from Tangshan Yutong Import And Export Corporation are manufactured using high-grade magnesite clinker and chrome oxide, fired at temperatures exceeding 1700°C to achieve direct bonding between periclase and spinel phases. The product exhibits a bulk density of 3.00 to 3.20 g/cm³ and a porosity of 12% to 15%, as stated in the source data, making it suitable for high-stress refractory linings. These bricks are designed for applications requiring resistance to alkaline slags and thermal cycling, such as steelmaking converters and cement rotary kilns.
The material composition is based on magnesia (MgO) and chromium oxide (Cr2O3), with typical industry-grade Cr2O3 content ranging from 10% to 20%, though the exact ratio is not specified by the supplier. The bricks are formed under high pressure and sintered to promote crystal growth and reduce glass phase content, which enhances slag resistance. Standard industry practice allows for minor variations in grain size and bonding density depending on firing profiles, but these bricks are engineered for low porosity and high structural integrity under load.
Buyers in steel, glass, and cement industries commonly specify these bricks for lining zones exposed to corrosive slags and fluctuating temperatures. The supplier does not state MOQ, lead time, or packaging details, but standard export packaging involves wooden crates with moisture-resistant lining. Buyers should confirm the exact firing temperature profile and thermal shock test results before ordering, as performance varies with microstructure. Trade terms are negotiable but typically follow FOB Tangshan or CIF terms.
| Material Composition | High-grade magnesite clinker with Cr2O3 (exact ratio not specified) |
| Bulk Density | 3.00 to 3.20 g/cm³ |
| Apparent Porosity | 12% to 15% |
| Cold Crushing Strength | Not specified; typical range for direct-bonded bricks is 40 to 60 MPa |
| Refractoriness Under Load (0.2 MPa) | Not specified; standard for this class is above 1700°C |
| Thermal Shock Resistance | Good resistance to rapid temperature changes; typical test involves 1100°C water quench cycles |
| Chemical Resistance | Resistant to alkaline slags; typical performance in low-acid environments such as cement kilns |
| Maximum Service Temperature | Up to 1750°C |
| Typical Grain Size | Typical periclase crystal size ranges from 50 to 200 microns in direct-bonded formulations |
| Packaging | Standard export packaging: wooden crates with moisture barrier; weight per crate typically 1000 to 1200 kg |
Tangshan Yutong Import And Export Corporation is based in Tangshan, Hebei Province, China, with a physical address listed in the Oriental Building on Jianshe Road. The company operates as an exporter of refractory materials, with no public information available on production capacity, years in business, or workforce size. Its trust tier is classified as harbor, indicating basic verification of business registration, but no certifications, audits, or client lists are disclosed.
The supplier does not claim to manufacture these bricks in-house or operate a kiln facility; it may function as a trading entity sourcing from regional refractory producers. No details are provided regarding quality control protocols, testing equipment, or third-party inspections. Buyers should request material test reports for each batch and confirm the origin of raw materials, as direct-bonded bricks from Tangshan may vary in composition depending on the source of magnesite clinker.
Direct-bonded magnesia chrome bricks are high-performance refractories manufactured from premium-grade magnesite clinker and chrome oxide, fired at elevated temperatures to achieve superior strength and slag resistance. These bricks are widely used in steelmaking converters, non-ferrous smelting furnaces, and cement rotary kilns. As a key import commodity in the global refractory market, buyers evaluate purity, bulk density, and thermal shock resistance when sourcing for steel plant and foundry applications.

Sourcing Direct-bonded Magnesia Chrome Bricks from Tangshan Yutong Import And Export Corporation - China Import Guide
Before ordering, verify the chemical composition of each batch with a certificate of analysis showing MgO, Cr2O3, SiO2, and Fe2O3 content. Confirm the firing temperature and cooling profile used, as these affect crystal bonding and thermal shock resistance. Request a sample for lab testing if the order exceeds 5 metric tons. Do not rely on supplier claims without third-party test data.
Logistics are typically handled via FOB Tangshan port, with containerized shipping in wooden crates. Lead time is not stated; buyers should confirm production scheduling and whether bricks are pre-fired or require final curing. Payment terms are negotiable but commonly involve 30% advance and 70% against copy of bill of lading. Incoterms should be clearly defined to avoid liability for customs delays or damage in transit.
Inspect bricks upon arrival for cracks, chipping, or moisture damage. Perform a visual check for uniform color and texture, which indicates consistent firing. Request batch-specific test reports for bulk density, porosity, and cold crushing strength. Retain samples for independent lab analysis if performance issues arise in service. Documentation must include origin certificates and material safety data sheets.
