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. |
