Filling Sand for Ladle Tapping Hole
Application Industry: Refractories for Steel Industry
Application Equipment: Ladle and LF Ladle Tapping Hole Filling
Size: Pre-mixed filling sand with 0.1 to 3.0 mm grain size (custom formulation on request)
Products Overview
Our Filling Sand for Ladle Tapping Hole is a granular refractory filler product engineered for ladle and LF ladle tapping hole filling service. CH Refractories can supply silica-based and Chrome-based filler according to customer’s requirement. Silica-based filler uses quartz sand as raw materials, mixed with lubricant and sintering aid. Chrome-based filler uses South-Africa Chrome ore as raw materials, mixed with lubricant, sintering aid, and deoxidizer, featuring good self-flow rate normally above 95%.
The Filling Sand for Ladle Tapping Hole product family is offered in five engineering-proven YL chemistry grades. The CH-YL80 grade is silica-based with silica content minimum 80%. The CH-YL50 grade is Chrome-based with silica content maximum 50% and chrome content minimum 25%. The CH-YL40 grade is Chrome-based with silica content maximum 40% and chrome content minimum 30%. The CH-YL30 grade is Chrome-based with silica content maximum 30% and chrome content minimum 35%. The CH-YL20 grade is Chrome-based with silica content maximum 20% and chrome content minimum 40%. All five grades deliver grain size 0.1 to 3.0 mm and moisture content maximum 0.5%.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Filling Sand for Ladle Tapping Hole grade is engineered to ASTM, GB/T, and ISO refractory standards.
