Foundry Grade Chromite sand is a complex compound of various elements. The main elements Chromium as Cr2O3, Aluminium as Al2O3, Silica as SiO2, Magnesium oxide as MgO. It is a lustrous, brittle, hard metal. Its colour is silver-grey and can be highly polished.
Our iron chromite naturally contains between 44% and 46% chrome, with a maximum 3% silica and the perfect chrome-to-iron ratio (1:1.5). The raw material is milled to an ultra-fine powder, 98% below 45 micron/ 325 mesh. This allows for better dispersal during your mixing processes and eliminates speckling.
1.1 Chromite sand 1.1.1 Primarily for use as either a molding sand or as a core sand in the production of steel castings. 1.1.2 Foundry grade chromite sand is derived from naturally occurring chrome ore deposits. The grains are irregularly shaped, angular and commonly with somewhat curved faces.The color is jet black with a metallic luster.

Chromite is a black sandy odourless material, which is free flowing when dry. It is insoluble in water and any common organic solvents Typical Specification Chromium as Cr2O3 = 45% min. Typical 46% Fe2O3 = 25% max.
chromite sand refractory grade Refractory grade CHROMITE is mainly used in chrome-magnesia or magnesia-chrome bricks. Chrome ore is able to overcome the typical disadvantages of magnesia (shrinking tendency and high temperature coefficient).
Chrome sand is a major component in refractory bricks that are used in the foundry industry to line furnaces, fireplaces, kilns, ovens, and other high-heat environments. The bricks must be able to withstand temperatures over 1700° C, have excellent thermal shock resistance, and have both acid and basic slag erosion resistance.
Foundry sand must adhere to strict physical and chemical specifications to ensure that castings are kept free of defects. Both foundries and sand producers have extensive quality control systems to test and maintain consistent specifications for sand, ensuring that all foundry sand from a particular source will generally have a very consistent
Sand reclamation has become a necessity in no-bake operations, particularly given the current challenges regarding the cost and availability of new sand. Foundries can no longer afford to operate with new sand alone and most are exploring how best to economically integrate sand reclamation systems into their processes. For a reclamation plant to realise the full value of a sand reclamation

Foundries represent a significant part of the world’s economy and are a large consumer of energy and producer of solid waste. Sand-handling processes can use 5–10% of a foundry’s total energy.
refractory is left on the sand surface. This layer or barrier can prevent or minimize the penetration of molten metal into the sand, can reduce or prevent “burn-on” and erosion of the sand and generally improves the quality of a casting surface. The benefits of a foundry coating are only achieved if the coating is the proper one for the job and
