抄録

  With a view to prevent the partial solidification of metal in the shot sleeve in aluminum die casting process, heat transfer coefficients of molten metal in the shot sleeve coated with insulating powder were investigated. They were determined by measuring the temperatures of a chill block, and also by simulating solidification in the sleeve. As a result it was found that both methods gave almost the same value, and that the heat transfer coefficients decreased approximately to 1/15 or 0.5 kW / ( m2 K ) by coating with insulating powder. The value was estimated to be sufficient to prevent the formation of solidified layers in the shot sleeve.
