Particle Covering Agent FAQ for Steel Ladles and Tundishes

A particle covering agent forms a layer over liquid steel during ladle or tundish handling. The Eco-Friendly Particle Covering Agent provides thermal insulation, spreads quickly across the surface, and isolates air to help reduce heat loss and secondary oxidation.

Its granular form suits steel plants that need a covering material for ladle or tundish operations. A plant reviewing a replacement for carbonized rice husk can assess how the selected grade spreads over the liquid surface and fits its existing addition practice.

Available particle sizes include 0-1 mm, 1-2 mm, 1-3 mm, 2-5 mm, and 3-5 mm. The product uses bauxite as its primary material, with Al2O3 content ranging from above 85% to above 88% across the listed grades.

The chemical composition and grain size can be adjusted for specific furnace requirements and operating conditions. When selecting a grade, provide the target size range, ladle or tundish application, and current addition method so the requested formulation matches the process.

The standard ladle addition is 1-1.5 kg per ton of liquid steel. For planning, multiply the liquid steel tonnage by the selected addition rate, then match the expected material use with the chosen package format.

The suitable amount also depends on the liquid surface condition and the operating requirements of the process. The production team should use the standard range as the starting point for its process review.

The standard tundish amount is 150-200 kg per operation. A buyer can estimate material demand from the number of tundish operations and then select a package size that fits the plant's handling routine.

The addition should follow the liquid surface condition and the requirements of the specific process. Include the tundish application and operating conditions when requesting a supply configuration.

Packaging options include 1-ton jumbo bags, 10 kg small bags, and 25 kg small bags. Jumbo bags suit bulk handling, while the small-bag formats support lower-volume handling or staged additions.

For a wholesale request, send the application, expected quantity, preferred particle size, and packaging format. These details allow the requested material configuration to be matched to the ladle or tundish operation.
