Advantages of chromite sand for foundry:

Advantages of chromite sand for foundry:
1. High strength: Chromite sand has high strength and wear resistance, which can ensure the quality of castings.
2. High hardness: The hardness of chromite sand is very high, which can improve the surface hardness and wear resistance of castings.
3. Anti-oxidation: Chromite sand can resist oxidation and is not easily affected by thermal oxidation, which can ensure the surface finish of castings.
4. Low cost: The price of chromite sand is relatively low, which can reduce casting costs.
Disadvantages of chromite sand for foundry:
1. Not easy to melt: Chromite sand has a higher melting point and requires a higher melting temperature to melt, which increases the difficulty of smelting.
2. Susceptible to moisture: Chromite sand easily absorbs moisture in the air, and moisture absorption will reduce fluidity and melting effect.
Chromite sand has certain advantages and disadvantages. Foundry companies should choose appropriate sand molds based on production needs and safety requirements.
