Al2O3-SiC-C Brick for Torpedo Ladle Working Layer
Application Industry: Refractories for Steel Industry
Application Equipment: Torpedo Ladle Working Layer Lining for Iron Transportation
Size: Standard brick geometry per torpedo ladle lining design (custom sizes available on request)
Products Overview
Our Al2O3-SiC-C Brick for Torpedo Ladle Working Layer is a high-performance carbon-containing brick engineered for torpedo ladle working layer lining service. The product family is manufactured from corundum, andalusite, flake graphite, and SiC as the main raw materials, bonded by phenolic resin. After being mixed, high-pressure pressed, and firing treated, the product family shows excellent slag erosion resistance, thermal shock resistance, abrasion resistance, and good performance for torpedo ladle working layer service.
The Al2O3-SiC-C Brick for Torpedo Ladle Working Layer product family is offered in four engineering-proven ASC chemistry grades. The CH-ASC18A grade features Al2O3 content minimum 65% and SiC+C content minimum 18% for torpedo ladle sidewall service. The CH-ASC18B grade features Al2O3 content minimum 65% and SiC+C content minimum 18% for torpedo ladle top service. The CH-ASC20A grade features Al2O3 content minimum 65% and SiC+C content minimum 20% for torpedo ladle impact area service. The CH-ASC20B grade features Al2O3 content minimum 60% and SiC+C content minimum 20% for torpedo ladle slag line service. All four grades deliver Bulk Density minimum 2.75 to 2.85 g/cm³ after 200 °C curing for 24 hours, Apparent Porosity maximum 10%, Cold Crushing Strength minimum 40 to 50 MPa after 200 °C curing for 24 hours, and Permanent Linear Change 0 to +1.0 percent after 1400 °C firing for 3 hours.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Al2O3-SiC-C Brick for Torpedo Ladle Working Layer grade is engineered to ASTM, GB/T, and ISO refractory standards.
