Abstract EN
Strips of magnesium alloy AZ31-B were cast on a simulator of a horizontal single belt caster incorporating a moving mold system.
Mixtures of CO2 and sulfur hexafluoride (SF6) gases were used as protective atmosphere during melting and casting.
The castability of the AZ31-B strips was investigated for a smooth, low carbon steel substrate, and six copper substrates with various textures and roughnesses.
Graphite powder was used to coat the substrates.
The correlation between strip thickness and heat flux was investigated.
It was found that the heat flux from the forming strip to the copper substrate was higher than that to the steel substrate, while coated substrates registered lower heat fluxes than uncoated substrates.
The highest heat flux from the strip was recorded for casting on macrotextured copper substrates with 0.15 mm grooves.
As the thickness of the strip decreased, the net heat flux decreased.
As the heat flux increased, the grain sizes of the strips were reduced, and the SDAS decreased.
The mechanical properties were improved when the heat flux increased.
The black layers which formed on the strips’ surfaces were analyzed and identified as nanoscale MgO particles.
Nano-Scale particles act as light traps and appeared black.
