Iron Chromite sand for casting has good high-temperature performance, mainly manifested as high temperature casting resistance, excellent slag resistance, small thermal expansion coefficient, outstanding thermal conductivity, no sharp corners in broken particles, and high strength. In addition, the moisture content and clay content of chromite sand are also important indicators of chromite iron sand.
Chromite flour 45um consumption is big for green glass bottle factories. Recently, we get 20 tons of chromite flour prepared for shipment.
To make sure long distance transportation, we make well packed package. Inner plastic bag and pallets avoid any moisture on the way.
For 20 GP container, load 20 tons.
Chromite Flour is fine powder made from Chromium ore sand by crushing and grinding process. The chrome flour with 46% Cr2O3 is an excellent mineral colorant , refractory, and wear resistance material.
The Cr/Fe ratio refers to the ratio of chromium content to Ferro content in chromite ore. The Cr2O3 content of Foundry Chromite sand is more than 46%, the iron (Fe2O3) content is less than 26%, and Cr/Fe ratio is between 1.55-1.60:1.
Iron Chromite Powder and Chromium Oxide Green, although both compounds of chromium, can also be used as pigments and coloring agents in ceramic glazes and glass products. However, they have significant differences and variations in chemical composition, physical properties, and application fields.
Chromite sand AFS45-55 is a commonly used model in sand casting. Its particle size meets the requirements of AFS Foundry Association. However, in practical applications, the ratio of fine powder under a 100 mesh sieve has a significant impact on the performance of casting sand. In the quality control process of casting grade chromite sand, 4-5 mesh screens are usually used for particle size distribution testing. The particles screened below 100 mesh and above 140 mesh are not further sorted. Recently, a customer has special requirements for the particle size of AFS45-55. Our lab conducted further tests on the particles under 140 mesh, 200 mesh, and 270 mesh sieves. The following are the test results:
