Why uniformity of South Africa chromite sand is important？
It is well known that South Africa chromite sand with a 46% content are primarily used in two industrial applications: ladle tundish nozzle filler and foundry molding sand. As a natural mineral product, chromite sand vary in size after crushing. Seiving with different mesh can get a particle size range that best meets the desired requirements. Generally, the more uniform the chromite sand, the better its performance as ladle well filler sand and casting sand.
First, in the ladle nozzle filler, chromium ore sand is responsible for resisting the high-temperature corrosion of molten steel and ensuring smooth flow when the ladle slide opens. The higher the uniformity of Cr-sand particles, the easier it is for drainage sand to flow out of the water outlet. Thereby improving the pouring rate of the continuous ladle.
Second, in the foundry industry, South Africa chromite sand are primarily used as molding sand and facing sand for castings such as high-manganese steel and ductile iron. Applicable casting processes include no-bake sand casting, shell casting, and coated sand casting. The primary function of chromite sand is to withstand the high temperatures and physical and chemical corrosion of molten steel, prevent sand from sticking to castings, and rapidly conduct heat to solidify the molten steel. The more uniform the chromite sand grain, the better the surface quality of the castings.
In the actual production of South Africa chromite sand, we carefully control the uniformity to meet the needs of customers in various fields.
