USage of Bitop L Series

Bitop L Series are engineered for use on a wide range aluminum or silicon-killed steel grades. Depending upon the application, Bitop L products are typically added to provide thermal insulation and minimize temperature losses after tap, or after processing at intermediate treatment facilities such as an LMF, RHD, VAD, AOD, etc. Bitop L Series products may also be used to provide optimum slag fluidity in order to facilitate test/temperature taking and allow for easier alloy/flux additions during processing at the intermediate treatment facilities.

Advantages of Bitop L Series

  • Excellent thermal insulation properties
  • Formulated for enhanced refractory protection
