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)
