Ladle filler sand material Chromite sand AFS45-50

Product Introduction of Ladle filler sand material Chromite sand AFS45-50
Chromite sand can be used in casting, refractory materials, steel ladle well filler and metallurgy. The product has good texture and high refractoriness. Chromite sand is a typical material to make chromite based filler sand for steel ladle with high pouring rate.
Chromite sand is mainly produced in South Africa and India, among which South Africa's chrome ore production accounts for 80 of the world's total production. However, due to technical limitations, most of the South African chrome ore cannot meet the requirements for direct use in the foundry and metallurgy industry.
Instead, Chromite sand from China can be used in the casting of steel parts after technical cleaning.

Applications of Ladle filler sand material Chromite sand AFS45-50

In steel production, Chromite Sand is used as well as a filler for protection of the sliding gate in large steel holding ladles.
In the ladle well filler, 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 temperatures, FeO in the chromite reacts to desolvate and form secondary spinel, which causes the volume of the sintered layer to change and crack. 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 a refined ladle.



FAQ:
Q: Where are you located?
A: Our factory is located in a tariff-free Zone at Lianyungang port. So it will be convenient 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 processes on original South Africa such as washing, magnetic removing, and sieving. So it is cleaner with fewer impurities, less magnetic content. The cleanness of chromite from us is just proper for the foundry industry. In the meantime, we will get a precise AFS size and make customized particle size distribution to the requirement.

Q: Do you have a limit of MOQ?
A: No. We don't have a limit on MOQ, but for small quantities, the transportation 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 lead time of FCL is 7-10 days. A bigger quantity will get a 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.
