Domes for arc furnace and arc furnace of direct current

Scope and purpose

The vaults are an alternative to replacing traditional typesetting refractory brick lining with a single refractory product used for arc steelmaking furnaces and DC arc furnaces.

Characteristics

The vault can be a product assembled from large-block elements – a finished vault, or the central part of the vault.

Basic indicators

Products are manufactured according to TU 1584-001-43539424-2018

 Benefits

  • Reducing the cost of liquid steel (cast iron) by reducing costs with efficient performance:
  • high resistance – 150-500 heats
  • lack of need for labor of refractory masons, warehouse of refractories
  • simplicity of installation and installation
  • minimum, not more than 0.4% coefficient of thermal expansion at 1600 оС
  • strength up to 120 MPa after temperature exposure 1100 оС
  • exact diameter of electrode holes
  • minimal heat loss during smelting
  • high mechanical strength during operation
  • the ability to feed the mixture through the arch hole
  • the possibility of re-use after replacing the central part
  • the ability to carry out assembly work at a temperature below 0 ° C
  • high accuracy of technological openings
  • minimum gaps between the electrodes and the arch (10-25 mm)
