Ceramic Foundry Beads

Molding Sand for Casting1 CERAMIC BEADSCeramic beads is a kind of refractory sand for casting, which is made of high alumina calcined bauxite, which produced by using special process--fusing, spurtting sand, getting rid of impurity and sieving.It can be used to make molds for multiplicate castings in various sizes, shapes and materials. Due to its inert property, it does not react with solvents, water, acid, or alkali. And It can be reused many times because of its excellent mechanical performance. That is, it can reduce the cost of production relatively. All of these advantages are proved by many domestic and abroad customers.2special propertiesCeramic beads is spheral and compact, so the fluidity, filling and molding character are excellent.The surface is smooth, not rugged, so it has super cohesiveness, coating character and high intensity with less organic additives.High content of Alumina, high refractory degree.Excellent compression resistance to cracking.Low reversible thermal expansion.Super spalling performance and good regeneration.3UsageORGANIC OR INORGANIC SELF-HARDEN CASTING MOULDFuran resin casting mould, Alkali-phenol resin casting mould, etc.HOT-HARDEN CASTING MOULDRCS mouldingGAS-HARDEN CASTING MOULDCold-box moulding,CO2 moulding.HOT MEDIA FOR FLUIDIZED BED FURNACE4Granular ShapeThe granular shape is globosely, it means glazed and compact surface
