What Affects Heat Retention
Ladle Covering Compound performance depends on ladle capacity, holding time, surface coverage, material spreadability, ambient exposure, and the plant's target temperature drop. A material that does not spread properly may leave exposed molten steel areas, while an unsuitable dosage may fail to deliver the desired insulation benefit.
PK INDUSTRIES reviews the ladle size, normal hold time, transfer distance, casting window, existing cover practice, and current temperature loss before recommending Radex, Cover Powder, or Insulating Powder grade and dosage.
How To Evaluate A Trial
A practical trial should compare temperature drop, surface coverage, spreadability, smoke or dust behavior, and operator handling against the existing practice. The material should cover the molten steel surface quickly and form an insulating layer that supports stable temperature holding.
Plants should record ladle capacity, start temperature, hold duration, temperature before casting, material dosage, and operator feedback. These details help refine dosage and grade selection for repeat supply.
