Overview

Chromite Sand in the steel industry  

l  In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles.

Chromium drainage sand is made of chromite sand and additives. It has the advantages of high specific gravity, good fluidity, high melting point, and no excessive sintering. In the chromium drainage sand, when the added amount of chromite is greater than 60%, the chromite is continuously distributed, and this distribution helps to form a continuous sintered layer. At high temperature, FeO in the chromite reacts to desolvate and form secondary spinel, which causes the volume of the sintered layer to change and cracks. In this way, when the sliding plate is opened, the unsintered drainage sand under the nozzle will flow out quickly, and the cracks in the sintered layer will rapidly expand, The sintered layer is completely destroyed under the action of the static pressure of molten steel, so that the purpose of automatic pouring can be achieved. Chromium drainage sand is used by most large steel mills, accounting for about 30% of the entire drainage sand for ladle, especially for refined ladle.
