refractory is left on the sand surface. This layer or barrier can prevent or minimize the penetration of molten metal into the sand, can reduce or prevent "burn-on" and erosion of the sand and generally improves the quality of a casting surface. The benefits of a foundry coating are only achieved if the coating is the proper one for the job and

If a foundry is reclaiming sand, residual binder contributes to Loss On Ignition (LOI) at the mold/metal interface. LOI values consistently above 2% (prior to adding new binder to the sand) may contribute to gas defects. New sand additions can be made to reduce LOI if a reclamation system is performing optimally.

The washing facility produces foundry, chemical and metallurgical grade concentrates. The chrome sand concentrates are sold domestically and also exported to countries including China, the US, Europe, Japan, Korea and Brazil. It also recovers chrome sand from foundry waste, generated by various foundries in the industrial areas around Johannesburg.

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.

This varies with each foundry environment. Generally a starting point is 3% moisture. This additive is a "necessary evil"; it is required to hold the molds together but also creates a number of other problems. This is the most important additive in a green sand system and must be controlled consistently.

The embedding of particles of dust and sand in the casting surface, results in dirt defect. Causes: (i) Cursing of mold due to improper handling and Sand wash (A sloping surface of sand that spread out by stream of molten metal). (ii) Presence of slag particles in the molten metal. Remedies: (i) Proper handling of the mold to avoid crushing.

Sand casting, or sand mold casting, is a popular method of producing non-ferrous alloy casts. Invented over 6,000 years ago, this process has undergone a number of changes and modernizations over the years, but the basic principals have remained the same. From small DIY operations to major commercial foundries, the technique has been replicated ...

Sand wash problem is generally encountered in sand casting operations. The form of sand mold surfaces can be eroded because of the hot fluxing metal. And this erosion can be seen on the surface of metal after solidification. Solution Of Sand Wash Problem: Obtaining required mold strength and providing non-turbulence flux of molten metal inside ...

Resin sand is a kind of foundry sand with synthetic resin (phenolic resin and furan resin, etc.) as the binder. The resin added is about 3% to 6% of the sand quality. Resin sand can harden fast when heated 1 to 2 minutes, and its dry strength is high, so the castings made are accurate in size, the surface is smooth, and the collapsibility is ...

In 2007, the American Foundry Society estimated (PDF) (5 pp, 1.94 , About PDF) that less than 30 percent of the 10 million tons of spent foundry sands generated annually are recycled. EPA believes a greater percentage of spent foundry sand can be safely and ...

These "sand core dryers," "mold dryers," or "core drying ovens" operate at 200°-400°F and dry molds or cores in 10 to 30 minutes, as opposed to 10- 20 hours needed for passive drying at ambient temperature. The wash is a water or solvent-based liquid or slurry suspension of zircon, magnesite talc, or graphite solids.
