Chromium filler sand is a refractory material for ladle made of chromite ore sand. It is better than silicon drainage sand and can increase the pouring rate of ladle. The chromite sand fineness for ladle filler sand is mainly 0.2-0.4mm,0.2-0.6mm, 0.2-0.8mm.
Chrome ore powder is one of the indispensable raw materials in industrial fields such as refractory materials, casting, glass manufacturing, and ceramic glazes. Chromium ore powder comes from natural chromite ore. Chromium ore with a chromium content of less than 40% can only be used in the metallurgical field for the smelting of ferrochrome metal. Only chromium ore with a chromium content of more than 40% is meaningful for deep processing. Raw materials with a chromium content of 40-42% in South Africa, 46-47% in Zimbabwe, and 48-50% in Zimbabwe are selected. The production process including ore selection, washing, drying, screening, and fine milling.
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.
