Chromite ore sand AFS55-60 for shell molding
Chromite ore sand AFS 55-60 is a high-quality casting sand for shell molding. This sand generally refers to the high thermal strength, long heat resistance time, and small deformation at high temperatures. It can take a tough task that silica sand can’t do.
It is achieved through special process formula technology (usually by adding a certain amount of silicone sand during film coating)
Chromite ore sand is an inert material whose chemical is very stable with excellent performance. It has high-temperature resistance, high strength, low expansion, and low gas generation.
Chromite sand PH value is 7.5-8. It doesn’t react with ferro and alloy while casting. Thus it can eliminate casting defects. Especially suitable for complex thin-walled precision cast iron parts (such as automotive engine cylinder blocks, cylinder heads, etc.) The production of high-demand steel castings (such as container corners and train brake buffer shells) can effectively eliminate casting defects such as sand sticking, deformation, hot cracking, and air holes.
