Specifications

Product Introduction of Chromite sand AFS30-35 for foundry

Chromite sand AFS30-35for foundry is widely used in investment casting, no-baked sand casting, lost foam casting,etc. the best chromite sand for foundry is from good quality mine in South Africa. the Cr2O3 purity of SA chrome ore is min 46%. Comparing with refractory grade chromite sand, the foundry chromite sand should be high Cr2O3 content and with good particle distribution. Foundry chromite sand will help foundries to get a smooth finish surface of steel castings.

Product Feature and Applications of Chromite sand AFS30-35 for foundry:

 

1.       Good resistance to alkaline slag and does not react with iron oxide.

in practical applications, chrome ore can avoid thermal chemical sand sticking on surface of casting. Thus it will save cost on further surface finish work.

2.       High Wetting angle to molten steel liquid.

that makes good wetability resistance to steel liquid. Chromite sand won't get react with molten steel. There won't be chemical sand sticking for casting steels.

3.       High thermal conductivity and thermal storage coefficient

It is several times greater than that of silica sand. that property of chromite sand can

Increase the cooling speed of melted steel liquid. on one hand, it prevent chemical reaction in high temperature. so casting will get off from the shell. It is easier to clean the casting surface.

on the other hand, it also increase the solidification process of molten steel. It will make less shrinkage and porosity of steel castings.

4.       High refractoriness

the resistance to high temperature will help chromite sand stable to molten steel.

5.       Low thermal expansion.

that property of foundry chromite sand will help to increase the unshaped defects on castings.

6.       Even particle sieve distribution. the chromite sand grit size is get strictly according to AFS standard. that will make the consistency of chromite quality.

7.       Low SiO2 content.It will help to prevent heavy leather defects on castings.

 

 

Applications of Chromite sand AFS30-35 for foundry:

 

Investment casting.

Shell molding for precise casting such as water glass shell molding.

Lost foam casting.

Sand casting.

Resin coated casting.

FAQ:

Q: Where are you located?

A: Our factory located in tariff free Zone at Lianyungang port. so it will be convince to export.

 

Q:What is your main market?

A: Our main market is local China and Asia-Pacific regions.

 

Q: What is the difference between your chromite sand and Original South Africa Chromite sand?

A: in our factory,we take production process on original South Africa such as washing, magnetic removing and sieving. So it is cleaner with less impurities, less magnetic content. the cleaness of chromite from us is just proper for foundry industry. In the meantime, we will get a precise AFS size and make customized particle size distribution to requirement.

 

Q:Do you have a limit of MOQ?

A:No. We don't have limit of MOQ, but for small quantity, the transporation cost would be high.

 

Q: Can you provide free samples?

A: Yes, free samples within 25 kgs are available. You only have to bear the express cost.

 

Q:What is the delivery time for one container?

A: Generally the leadtime of FCL is 7-10 days. Bigger quantity will get longer delivery time.

 

Q:What is the HS code of Chromite sand?

A: the chromite sand HS code is 2610000000.

 

Q:Do you get MSDS of chromite sand?

A:Yes.You could download it from our website or get it from our sales team.
