Thermal insulation mixture USL-01

Thermal insulation mixture (USL-01) used for ladles, molds and moulded forms, intended to reduce heat.

The mixture shall comply with the requirements and standard values specified in the Table:

Mixture grade Content, %
C SiO­2, min Moisture, no more than
USL-01 (1) 1-5 65 1.0
USL-01 (2) 1-5 70 1.0

Bulk weight (unrammed): 500-700, kg/m3

The mixture shall be packed in marked polypropylene bags (or paper bags with a waterproof layer) by 5-15 kg (bag weight shall be agreed upon with the customer) and placed into marked soft containers of the big bag type.

The economic effect of the use of warming mixtures:

  1. Reducing the consumption of metal on the profitable part of the ingot.
  2. Improving the yield of steel.
  3. Reduction of shrinkage defects, macrostructure defects and ingot surface.
  4. Partial assimilation of non-metallic inclusions.
  5. Reliable protection against secondary oxidation and the ingress of nitrogen into the metal.
