JNY-TCS is a kind of refractory particle with diameter of 0.020mm~3.350mm, mainly made of Al2O3-SiO2. It is ball-shaped particle made from bauxite by high-temperature melting in electric-arc furnace, spraying and cooling.
1. As solid spherical sand, the surface area is small, which can reduce one third the amount of binder (resin, or R2O-nSiO2 etc.). Good fluidity, easy to fill and close-grained without dead space when producing sand mould and sand core. Low gas evolution and high permeability, can reduce defects, increase the overall yield of casting and lower the cost of casting material.
2. High refractoriness, low coefficient of thermal expansion with good stability under high temperature. During the process of foundry, the sand is easily dispersed, easy to clean, no sintering and gluing on the casting, which reduce the deformation of the casting, reduce the clean-up work and lighten labor intensity.
3. Reasonable grading composition of the particle, improve the strength of casting mould and core.
4.The bulk density of JNY- TCS is 1.79-1.87g/cmu00b3, lower than the bulk density of chromite sand (2.5~2.9g/cmu00b3), the sand core is easy to move with light weight, and also can reduce the usage amount of sand.
5. The sand is man-made by melting under high temperature, so it has stable chemical parameter, unified physical properties. PH value is neutral; both acid and basic binder agent can be used.
6. No cracking under high temperature, high solidness, high recycling usage rate.
Product Specification / Models
Al2O3:65-82%, SiO2:15.32-21.6%, Fe2O3:1.5-3.0%,
Application / Models
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 of 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.
