Recycling of Refractory Materials

     In a word: Recycle the refractory materials by decomposing them.

    The type of refractory materials used in a furnace differs by the position. All kinds of used refractories mixed together make it hard to keep good quality, so it is necessary to classify refractories before reusing them. They can be classified by magnesia, alumina, carbon-based, non-carbon-based.

In addition, for the dissimilar materials  or iron mixed in, we can use some ways to pick them out, such as the method of magnetic separation. First, the used refractory materials should be crushed to 200mm~ 400mm, and then reduce to smaller than 20mm after impacting, compression or snipping, so as to be easy used.

For the refractories mixed with iron, we can use the way of electromagnetic separation, on the effect of magnetic strength higher than 12000 GS, making the content of iron in the used refractories with the size of 5~10mm less than 2%. While reusing the slit after crushing and after removal of iron powder as raw materials, we should classify them by particle size. The classification is generally done by using some metal mesh sieves, put the large mesh screen in the above and the small mesh screen under the large ones, keep continuously screening. In the process of crushing, grinding and classification, we should notice that not let the dust spread, sealing the device and recycling refractories in duster. The left dust also can be added to raw materials of landscape bricks.

Where to buy refractory products at low price?

For steelmaking, metallurgy and chemical industry, safety is as important as cost, so both quality and price are essential, that means it’s a key issue to choose the right refractory materials and products.

As we all know that China is the world’s largest producer and exporter of refractory materials, and Henan Province is the largest production base in China as Henan is rich in the raw materials. It is wise to buy refractory products from suppliers located in Henan, because there are lots of choices and usually these companies supply products with good quality and at a relatively lower price.

To select a good company to buy refractory products and materials, firstly, we need to see when it is founded. A long history does make a company more professional and experienced. Secondly, whether it has its own research team. Only with that can a company meet the requirements of different customers. Thirdly, we should notice its annual output. It shows a company’s scale and sales status. Of course the three factors are not the whole elements to consider, but they are truly worthy of our attention.

When you read here, I guess that you are really seeking refractory suppliers and are in need of refractories. Just try to look for company in the consideration of the above three factors, you will finally find your right supplier.
