Description by Manufacturer

Chrome Ore Sand AFS 25-30 Chromite Grain 0.4-0.8mm for Sale Orgininal From South Africa

Chrome Ore Sand AFS 25-30 Chromite Grain 0.4-0.8mm for Sale Orgininal From South Africa is a non siliceous casting surface sand and molding sand. The main component of chromite sand AFS 45-55 is natural chromite, accompanied by iron oxide and aluminum oxide. After water washing and four rounds of magnetic separation, the chrome ore sand manufacturer will control the content of silicon dioxide and sediment to make it more suitable for the casting field. Chromium sand used in casting has the characteristics of high sintering temperature, prevention of chemical penetration, excellent thermal conductivity, and small thermal expansion when encountering heat. Chromite sand AFS 45/55 (50-100mesh) is mainly used for surface sand of large thick wall castings, core sand of easily sticky sand parts of castings, and alloy steel castings with high pouring temperature. In terms of molding sand and other aspects of the product.

Applications of Chrome Ore Sand AFS 25-30 Chromite Grain 0.4-0.8mm for Sale Orgininal From South Africa:

1. Large scale thick walled casting: Chromite sand combined with sand casting, furan resin self hardening sand, water glass self hardening sand and other processes are used for large volume and weight cast iron and steel castings. It can cool the castings in a predetermined order, which is conducive to improving the internal tightness of the castings and enhancing their strength. In addition, for the process of using silica sand, chromite ore sand can be used as surface sand instead of silica sand in key areas where porosity and veins are prone to occur, which can effectively prevent casting defects such as cracks and porosity.

2. Lost foam casting. In lost foam casting, using chrome ore sand can prevent defects such as sand inclusion and sticking caused by quartz sand casting. Used for manufacturing castings such as valves and impellers made of high chromium cast steel and high manganese steel materials.

3. Shell casting: Chromite sand can be used as a core sand material for complex components in shell casting, making sand cores. Used for producing high-precision, smooth surface 304316 stainless steel castings and carbon steel precision castings. It can effectively prevent the problem of sand sticking in the inner cavity of castings.

4. Sand casting: Chromite sand can also be used for sand casting, such as sand casting, water glass self hardening sand casting, etc., to produce various large, medium, and small parts, such as pump bodies, pipelines, valves, etc.
