Webb10 apr. 2024 · As a result of the interfacial reaction, Al 2 O 3 accumulation coupled with SiO 2 reduction in mold flux during continuous casting is the main factor that deteriorates cast product quality and process efficiency. Some investigations on understanding the reaction mechanism between high-Al steel and the CaO–SiO 2-based mold flux have been carried … WebbIn case of Yyn0d11 (or Yyn0d1), the buried delta will set up circulating current within Delta when there is current in one phase on secondary side. This will show up as current in two phases on primary side (for a single phase to ground fault on secondary side). The behaviour is similar to if it were Dyn instead of Yyn with buried Delta tertiary.
