Coatings for Tundish,Tundish Material

Coatings for Tundish

Tundish coating of HN series is characterized by easy painting, no crack, erosion resistance, long service life and easy disassembly. Compared with using the insulation board, the tundish coating series can reduce nonmetallic inclusion in liquid steel, enhance cleanliness of liquid steel, improve steel property, reduce cost and increase performance.

Tundish coating HN-ZBTM4 is prepared specially for some types of steel with strict requirements on phosphorus content such as stainless steel, which compared with common tundish coating, can prevent phosphorus pollution of steel in tundish.

Nozzles are either pressed or pre-cast depending on the composition.

 

Export Obstacle about Refractory Scrap

Because of the low price of refractory scrap, the market on such materials is huge around the world, while not everyone can manage to get what they want.

Recently we Yilong Refractory receive some inquiries about used/rejected or defective refractories, such as fused cast AZS refractories (zirconia-corundum refractories). Even the customer has no requirement on size, or shipping date, it’s a little difficult for us manufacturers to supply such kind scrap to other countries. You may ask WHY.

Firstly, even the refractory scrap has much using potential, though it can’t be equal to end refractory product. Usually, the manufacturer will recycle the refractories and then put them into reusing. So the manufacturers are more likely to reutilize than exporting the materials.

Secondly, as we all know that the declaration to the customs is complex in many countries, especially China. So only in the case that the amount is very huge and all other trading information is ok, such as payment terms. Otherwise, the manufacturer may possibly not promise to supply.

OK, that’s all my opinions. All your ideas are welcome, different, similar or the same.
