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.

World Crude Steel Production in 2013

It is said by WSA that world crude steel production reached 1,607 megatonnes (Mt) for the year 2013, increased by 3.5% compared to 2012. Furthermore, the growth came mainly from Asia and Middle East while crude steel production in all the other regions decreased in 2013 compared to 2012.

From the steel production data in WSA, it is concluded that refractory products are in higher demands in Asia and Middle East in the past year. The 2014 demands in those two regions are not still sure, increase and decrease are both possible, while there is no doubt that refractory and insulation products at a relativily stable and big quantity are required for steelmaking plants every month. Asia and Middle East are still main refractories market with much potential by now.
