Chrome ore foundry sand AFS 45/55 (particle size of about 0.25-0.35mm) is used as casting sand for railway turnout accessories. With its unique physical and chemical properties, it has excellent performance in high temperature stability and resistance to metal penetration.
Chrome powder 325mesh is fine chromite flour with 97% granular smaller than 45um. By milling 46% raw chrome ore sand would get Chrome powder with Cr2O3 45-46%.
Recently, 500 Tons of foundry chromite sand AFS45-50 are prepared. SGS make the inspection before delivery.
The chromium materials used to make magnesia-chromite bricks are natural chromite grain and chromite powder with a chromium content of more than 46%. Chromite ore powder has the following performance advantages:
Chromite filler mess, also known as ladle well filler or nozzle filler sand. It is an important part of furnace refractory material. The raw material of Chromite filler mess is chromite sand and other additives.
The particle size of foundry sand has a significant impact on the casting process. Foundry chromite sand not only requires uniform particle size, but also has requirements for fine powder content. Controlling content of fine powder is very important below 140mesh and 200mesh.
