Products Overview
Our Cement bonded castable is a high-performance refractory product engineered for industrial furnace, rotary kiln front kiln mouth, disintegration furnace, kiln hood, and other high temperature equipment service. The high-aluminum refractory castable is made of high-aluminum aggregate, high-aluminum fine powder and micro-silica powder through reasonable machine, plus water-reducing agent and high-aluminum cement. The cement bonded castable has high temperature performance and is widely used in hardware, smelting, chemical, non-ferrous metals and other industries. It is particularly prominent in the steel industry. It is mainly used in the front kiln mouth, disintegration furnace, kiln hood and other parts of the rotary kiln.
The Cement bonded castable product family is offered in five engineering-proven GLJZ and NTJZ chemistry grades. The GLJZ-85 grade features Al2O3 content minimum 85% for highest-demand industrial furnace service, with Refractoriness minimum 1780 °C, Cold Crushing Strength minimum 35 MPa after 110 °C drying for 24 hours, Modulus of Rupture minimum 6 MPa after 110 °C drying for 24 hours, and Test Temperature After Burning minimum 1500 °C. The GLJZ-70 grade features Al2O3 content minimum 70% for high-demand industrial furnace service, with Refractoriness minimum 1720 °C, Cold Crushing Strength minimum 30 MPa, Modulus of Rupture minimum 6 MPa, and Test Temperature After Burning minimum 1450 °C. The GLJZ-60 grade features Al2O3 content minimum 60% for general demand industrial furnace service, with Refractoriness minimum 1700 °C, Cold Crushing Strength minimum 25 MPa, Modulus of Rupture minimum 5 MPa, and Test Temperature After Burning minimum 1400 °C. The NTJZ-50 grade features Al2O3 content minimum 50% for lower-temperature industrial furnace service, with Refractoriness minimum 1660 °C, Cold Crushing Strength minimum 20 MPa, Modulus of Rupture minimum 5 MPa, and Test Temperature After Burning minimum 1400 °C. The NTJZ-42 grade features Al2O3 content minimum 42% for low-temperature industrial furnace service, with Refractoriness minimum 1640 °C, Cold Crushing Strength minimum 20 MPa, Modulus of Rupture minimum 4.6 MPa, and Test Temperature After Burning minimum 1350 °C.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Cement bonded castable grade is engineered to ASTM, GB/T, and ISO refractory standards.
