IRON RESIDUE / CONTAMINATION ON ... Stainless Foundry
The iron is converted to iron oxide which can then be removed by abrasive blasting. This method is acceptable for unmachined sand castings since the scaling which occurs is not detrimental. The sand blasting abrasive must be free of iron contamination or the part will be recontaminated.
Sand Casting Process, Defects, Design
Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace ...
