Main Advantage
1 | Stabe quality on the chemical composition |
2 | Perfect grain round shape and various grain sizes |
3 | High gas permeability |
4 | High temperature resistance |
5 | Good break down and fast curing and good release |
6 | Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level |
7 | Smooth surface of spherical shape greatly improves collapsibility after pouring |
8 | Very low thermal expansion ensures fewer or no casting defects such as veining and deformation |
9 | Excellent thermal conductivity and heat absorption capacity close to that of Zircon |
10 | Superior refractory equivalent to Zircon and Chromites |
Applications
1 | Widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making |
2 | Replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine. |
3 | Replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand). |
4 | Widely used as dry sand and sand box for EPC process and V method of casting processes. |
5 | Widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.). |
6 | Widely used as cleaning sand for copper and aluminum alloy castings. |
