  • Chromite - ScienceDirect

    Jan 01, 2016· Chromite sand is the best sand medium for chilling metal. Chromite sand has the ability to draw heat from the molten metal, allowing the metal to skin over faster and minimizing burn-on. Excessive burn-on will need to be removed before heat treating, but it can also lead to other issues, causing castings to be scrapped. Foundry-grade chromite

  • Chromite (Cr2FeO4) CrFeO4 - PubChem

    Sand used in the foundry industry is washed, graded, and dried. Since silica sand is common and inexpensive, it is the most commonly used mineral. However, when physical or chemical conditions dictate, other sands are chosen, such as zircon, olivine, or chromite. Chromite foundry sand is used in the ferrous and copper casting industries.

    As chromite sand is widely used in steel/iron castings, a need was felt to prepare the standard on methods of test based on the requirements of IS 6788 : 1973. This standard has been prepared in different parts. This part ( Part 3 ) covers the chemical analysis of chromium, and other parts are:

  • Bag Sand Comparison Test - 6mmBR

    Chromite typically sells for about 25-30% less than Zircon (comparing bulk prices of both types of sand). Chromite sand is black in color. So when you buy "heavy sand," make sure you are getting what you pay for. 1.00 pound of Chromite displaces 152cc vs. 295cc for Play Sand. So, that means Chromite is 94% heavier than an equal volume of Play Sand.
