Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.

4.1 Introduction. Used foundry sand (UFS) (Fig. 4.1) is a discarded material coming from ferrous (iron and steel) and nonferrous (copper, aluminium, and brass) metal-casting industry to create molds and cores. About 1 ton of foundry sand for each ton of iron or steel casting produced is used ( Siddique and Noumowec, 2008 ).

most iron foundry green sand systems, the ideal screen distribution would be a four screen sand (at least 10% or more on four adjacent sieves), with a minimum of 10.0% on the 140 screen. The amount on the 140 screen is important for casting finish. Most aluminum and brass foundries run even higher on the 140 screen. 2. Compactability

The objective of this research is to create a model where different amounts of new sand and core sand are added to system sand, so that the green sand's properties and casting results can be evaluated. Initial work by the Green Sand Committee of CISA has shown that certain levels of new sand can be added, along with new clay/additives, to ...

The resin binder system is the primary source of organic constituents in foundry sand. Green sand systems have been shown to have lower potential for leaching organic compounds. The primary organic constituents from foundry sand are acetone and 1,1,1-trichloroethane (EPA 2002a). Tikalski et al (2004) found that most organic

Typical foundry sand systems generate waste particulate bond material, much of such particulate bond material being collected in the dust collection system, amounting to about 25 percent to about 50 percent by weight of the particulate make-up bond material which is being fed to the sand systems. Restated, only about 50 percent by weight to ...

The sand casting process contains six basic steps. While proper equipment and experience is required to produce a casting free of defects, the sand casting process itself is actually quite simple: 1. Create a Mold. The first step is to create the mold for the casting. A sand mold is formed by packing sand into each half of the mold (learn more ...
