Product Description

China manufacturer of Ceramic Foundry Sand for lost foam casting

Ceramic Foundry Sand is made from high quality bauxite, by re-fused, granulated screened and blown to ball shape. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.

Physical Character

composition	content	shape	Spherical,round ball
Al2O3	70-75%	color	Brown,black-brown,taupe
SiO2	8-20%	Refractoriness	2050℃
Fe2O3	≤ 3%	Liner thermal expansion	(20-1000 ℃) 6 × 10-6/℃
TiO2	≤ 3.5 %	Bulk density	1.95 -2.05g /cm3
CaO	≤ 0.45 %	Ture density	3.4g /cm3
MgO	≤ 0.35 %	thermal conductivity	(1200 ℃)5.27W/M•K
K2O	≤ 0.33%	Size range	6-320mesh
Na2O	≤ 0.08 %	PH value	7-8

Advantage

Perfect round ball shape	Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin use level
Perfect round ball shape	Smooth surface of spherical shape greatly improves collapsibility after pouring
High refractoriness	Superior refractory equivalent to zircon and Chromites
	Higher than silicon sand, can be used for casting various materials.
	Non-stick, non-sintering on the casting, which reduces the deformation of the casting.
Low coefficient of thermal expansion	Can be comparable to the zircon sand.
Low coefficient of thermal expansion	Ensures fewer or no casting defects such as veining and deformation.
Low gas evolution and high permeability	Can reduce defects, increase overall yield of casting and lower the cost of casting materials.
Low bulk density	The bulk density is 1.79-1.87/cm3, lower than the chromite sand of 2.5-2.9/cm3.The sand core is easy to move with light weight, and also can reduce the usage amount of sand.

Application

foundry ceramic sand is widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making.

foundry ceramic sand is widely used as cleaning sand for copper and aluminum alloy castings.

foundry ceramic sand is widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).

foundry ceramic sand is widely used as dry sand and sand box for EPC process and V method of casting processes.

foundry ceramic sand replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand).

foundry ceramic sand replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine.
