Chrome sand is the perfect material for hot metal casting, it is also an excellent ladle filler preventing contact between the molten steel and the ladle slide gate system. Chrome sand is also used in the production of magnesite chrome refractory bricks which usually contain over 33% of chromium and in the manufacture of chrome conundrum refractory bricks, providing resistance to abrasion and high temperature.
Chrome flour and chrome sand, as refractories, are a crucial part of ladle sand.
Continuous casting relies upon ladles to move molten metal from the furnace to where they are to be casted, such ladles (often referred to as pots) are large pieces of equipment that are lined with refractory materials so as to avoid solidification of the metal. A key feature of the ladle is the slide gate, which allows the molten metals to be released from the ladle into its next process.
Ladle sand is a type of compound sand used to protect the tap/slide gate at the egress point of the ladle, and at other points throughout the pot. As a refractory material, often containing quartz and other high performing refractories such as chrome sand, filler sand has an excellent tolerance for temperature and a low reactivity with the molten metal.
