The black powder in the lost foam coating is chromite powder. The size maybe 325#. It is often used in casting coatings. The reasons are: Precise fineness, Low moisture content, High refractory temperature, Excellent thermal conductivity, Good chemical stability
Why is foundry chromite sand used as the raw material for anti-sticking sand in cast steel?
Why is foundry chromite sand used as the raw material for anti-sticking sand in cast steel?It has a stable heated volume and high thermal conductivity. When in contact with molten metal, it not only has a good effect of resisting alkaline slag, but also has the characteristics of solid phase sintering, which can well prevent the penetration of molten metal and avoid the occurrence of sticking defects.

Why is HEVI chromite sand used as facing sand for steel castings?
Why is HEVI chromite sand used as facing sand for steel castings?The main reasons for choosing chromite sand as the surface sand for steel castings include its excellent physical and chemical properties, as well as its specific role in the casting process.
Why add foundry chromite sand during casting?
Why add foundry chromite sand during casting? Chromite sand is often used as the surface sand of large steel castings in casting production, which can effectively prevent sand from sticking to the surface of castings and improve the quality of castings. It has a stable heated volume and high thermal conductivity. It has a good resistance to alkaline slag when in contact with molten metal, and it has the characteristics of solid phase sintering, which can well prevent the penetration of molten metal and avoid the occurrence of sand sticking defects.
