Hanger brick for industrial furnace
Application Industry: Refractories for Industrial Furnace
Application Equipment: Industrial Furnace Charge Gate, Discharge Gate, and Partition of Annular Heating Furnace
Size: Custom hanger brick geometry per industrial furnace design (free engineering on request)
Products Overview
Our Hanger brick is a high-performance refractory product engineered for industrial furnace charge gate, discharge gate, and partition of annular heating furnace service. Partition suspending bricks are produced by Zhengzhou caihua with light weight mullite aggregate by low cement castables. It is characterized with good thermal shock resistance and high strength, and widely used at charge gate, discharge gate and partition of annular heating furnace to prevent cold gas from entering for industrial furnace service.
The Hanger brick product family is offered in two engineering-proven DG chemistry grades. The CH-DG1.8 grade features Al2O3 content 1.8±0.1% for general industrial furnace partition service, with Bulk Density minimum 2.45 g/cm3, Cold Crushing Strength minimum 15 MPa after 110 °C drying for 24 hours and minimum 20 MPa after 1200 °C firing for 3 hours, and Permanent Linear Change -0.8 to 0 percent after 1200 °C firing for 3 hours. The CH-DG2.0 grade features Al2O3 content 2.1±0.1% for higher-demand industrial furnace partition service, with Bulk Density minimum 2.6 g/cm3, Cold Crushing Strength minimum 20 MPa after 110 °C drying for 24 hours and minimum 25 MPa after 1200 °C firing for 3 hours, and Permanent Linear Change -0.6 to 0 percent after 1200 °C firing for 3 hours.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Hanger brick grade is engineered to ASTM, GB/T, and ISO refractory standards.
