Heat transfer coefficient at the metal–mould interface in the unidirectional solidification of Cu–8%Sn alloys

Effect of pressure on heat transfer coefficient at the metal/mold interface of A356 aluminum alloy

“…The heat transfer coefficient variation with time after pouring is the key factor to control the solidification. Several studies have attempted to quantify the transient interfacial metal/mold heat transfer coefficient, h i , emphasizing different factors which affect heat flow across such interfaces during solidification [2][3][4][5][6]. These factors include the thermo-physical properties of contacting materials, casting geometry, orientation of casting-mold interface with respect to gravity (contact pressure), mold temperature, pouring temperature, roughness of mold contacting surface and mold coatings [7][8][9][10].…”

Analysis of Temperature Field, Heat and Fluid Flow of Two-Phase Zone Continuous Casting Cu–Sn Alloy Wire

“…After solidification, air gap developed between the alloy and the mold because of solidification shrinkage. The heat transfer between the alloy and the mold was performed through the air gap [14][15][16].…”

Experimental determination of heat transfer coefficients during squeeze casting of aluminium

“…Controlling both stages is of major importance for obtaining sound casts with the required geometry and mechanical properties as observed by (Kobryn and Semiatin, (2000), Browne and O'Mahoney, (2001) and Martorano and Capocchi, (2000). When molten metal is poured into the mould cavity, it is initially in the liquid state with a high fluidity.…”
