Application Industry: Refractories for Steel Industry
Application Equipment: Ladle Furnace (LF) Electrode Area Triangle Zone
Size: Custom pre-cast shapes geometry per LF furnace electrode triangle zone design (free engineering on request)
Products Overview
Our Pre-cast Shapes for Electrode Area of Ladle Furnace (LF) is a high-performance refractory product engineered for LF furnace electrode area triangle zone service. The product family is manufactured from high-quality corundum, fused spinel, and fused mullite as main raw materials with low cement castable production process. The product family features high strength, excellent thermal shock resistance and erosion resistance, and long service life for LF furnace electrode area triangle zone service.
The Pre-cast Shapes for Electrode Area of Ladle Furnace (LF) product family is offered in four engineering-proven LFY chemistry grades. The CH-LFY80 grade features MgO+Al2O3 content minimum 80% for general LF furnace electrode area triangle zone service. The CH-LFY85 grade features MgO+Al2O3 content minimum 85% for higher-demand LF furnace electrode area triangle zone service. The CH-LFY90 grade features MgO+Al2O3 content minimum 90% for high-demand LF furnace electrode area triangle zone service. The CH-LFY92 grade features MgO+Al2O3 content minimum 92% and Cr2O3 content minimum 2% for highest-demand LF furnace electrode area triangle zone service. All four grades deliver Bulk Density minimum 2.75 to 3.05 g/cm³ after 110 °C curing for 24 hours, Cold Crushing Strength minimum 40 MPa after 110 °C curing for 24 hours and minimum 60 MPa after 1500 °C firing for 3 hours, and Permanent Linear Change ±0.5 percent after 1500 °C firing for 3 hours.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Pre-cast Shapes for Electrode Area of Ladle Furnace (LF) grade is engineered to ASTM, GB/T, and ISO refractory standards.
