The first modelling step is core shooting where expanding air is the driving force for sand flow from a core shooting machine into the core box. Coupled two phase flow modelling of air and granular material is required to represent the process sufficiently. The final process step in core manufacturing is core curing and moisture transport where ...

Depending on the gas-permeability of the mixture, gases will either escape the mold through the core prints or get trapped in the solidifying metal. Chemically bonded sands are used to produce cores primarily. Out of the many types, furan sand is the most prevalent no-bake mixture that is used in the foundry industry.

Images of artificial sand and mud core preparation are shown; (a) schematic diagram of artificial core structure, (b) frozen sand layer, (c) mud layer after pre compaction, and (d) inserted image in rubber sleeve. A thermocouple (Chino, Type-T) was set to measure the water temperature at the inlet. The injection of water was controlled by ...

Artificial sand is produced by reducing larger pieces of aggregate into sand-sized aggregate particles. Manufactured sand can be manufactured to be a certain grain size that the buyer chooses, while natural sand can be a mix of coarse and fine grains. Manufactured sand tends to be more angular and flaky due to the crushing process.

A total of 22 artificial unconsolidated sand packs and natural consolidated rock cores were employed in this study. Table 1 gives the composition and image resolution of each porous sample and Fig. 1 illustrates the CT images of each porous sample used in this study. As for unconsolidated sand packs, the glass beads with spherical grain shapes and quartz sand …
