In this investigation four parameters are considered namely chill distance, chill thickness, pouring Horizontal direct chill (HDC) casting is one of the important manufacturing processes for producing aluminum billets. The casting machine that was investigated and used as a reference for the numerical model, was the HDC casting machine at Alcoa Fjarðaál in Iceland Direct-chill casting of aluminum alloys is a well developed technology with a rather long history [1, 2, 3]. Grandfi eld, John The objective of this study is to investigate bleedouts in Horizontal Direct Chill casting process and to make a complete finite volume model of such process. An experimental study has been conducted on carbon steel WCC (ASTM A/A M WCC) ball valve body casting using ms chills. In this study, we tried to simulate and optimize HDC casting to overcome these challenges Because of its horizontal nature and gravity efects, controlling HDC casting still remains a challenge. At the same time, despiteyears of extensive research and practice, the formation of structure, defects and properties of billets and ingots produced by direct-chill (DC) casting is still not completely understood This article investigates the effect of mild steel chills on steel casting in sand mould to minimize shrinkage defects.

An experimental study has been conducted on carbon steel WCC (ASTM A/A M WCC) ball valve body casting using ms chills. Chills are typically made of cast iron, but It has been observed that chill has a significant impact on properties of the cast specimens. Others are increasing water chill­ ing in direct-chill casting, employing the electroslag remelting process and mak­ ing billets by compacting atomized liq­ uid Horizontal direct chill (HDC) casting is one of the important manufacturing processes for producing aluminum billets. In this investigation four parameters are This article investigates the effect of mild steel chills on steel casting in sand mould to minimize shrinkage defects The objective of this study is to analyze bleed-outs in Horizontal Direct Chill (HDC) casting process by using a finite element model (FEM). Because of its horizontal nature and gravity eects, Chills are used to support enhanced rate of solidification in sand castings mainly to reduce porosity and improve mechanical properties. HDC casting machines for aluminium The objective of this study is to investigate bleedouts in Horizontal Direct Chill casting process and to make a complete finite volume model of such process. The finer grain structure and better mechanical properties were observed by controlling internal chills on properties and microstructure of aluminium alloy castings using cylindrical form of the chill of the same material; evaluating effects of temperature Placing fusible chills in castings increased the number of graphite spheroids in the microstructure and exhibited no graphite degeneration. The casting ingots.
