Refractory scrap refers to discarded or waste materials that have been used in high-temperature applications, such as furnaces, kilns, or reactors. These materials often consist of refractory bricks, castables, or coatings that have become worn out or damaged during their service life. Refractory scrap can be recycled or repurposed for use in the production of new refractory products.

How moisture content in refractory affect performance of refractory?
Moisture content in refractory materials can lead to thermal spalling and cracking when exposed to high temperatures. It can reduce the strength and lifespan of the refractory material by promoting thermal shock and weakening its structure. Additionally, moisture can chemically react with certain refractory materials, causing them to lose their properties and effectiveness in high-temperature applications.
What is a common refractory material?
A common refractory material is alumina, which is an oxide of aluminum. Alumina has high temperature resistance and is commonly used in industrial furnaces and kilns due to its ability to withstand extreme heat.
What is the bulk density of refractory cement?
The bulk density of refractory cement can vary depending on the specific formulation, but it typically ranges from 1.8 to 2.2 g/cm3.
What is a refractory element?
A refractory element is an element that has a high melting point or heat resistance, making it suitable for use in high-temperature applications like furnaces or jet engines. These elements are often used as components in materials that need to withstand extreme heat without deforming or melting. Examples of refractory elements include tungsten, tantalum, and niobium.
What is permanent linear change in refractory material?
Permanent linear change in refractory material refers to the dimensional change that occurs in the material after it has been exposed to high temperatures. This change is irreversible and can affect the overall performance and integrity of the refractory material. Understanding and controlling permanent linear change is important in ensuring the longevity and efficiency of refractory linings in industrial applications.
Is there any export obstacle about refractory scrap?
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 Changxing 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.

Why did Yilong Refractory change their name into Changxing Refractory?
Because of Changxing Refractory's largest investment, Yilong Refractory was renamed as Changxing Refractrory.
How do you use refractory in a sentence?
1) The virus was refractory to the medication. 2) The refractory class was unable to get anything done.
Where you can get refractory concrete?
Refractory Engineers Indianapolis Indiana 3172732000
What is mag-dolo refractory?
magnesium-dolomite based refractory
Will the refractory product quality and services also change as the name of Yilong Refractory changed into Changxing Refractory?
The only change of Yilong Refractory is its name which has changed into Changxing Refractory. Its product quality, pre-sale and after-sale services remain unchanged.
What is refractory insulation?
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
2 Define refractory period and differentiate between absolute and relative refractory periods?
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
What type of refractory lining use for DRI melting in induction furnace?
SiO2 refractory
What super refractory?
Super Refractory is a refractory material which retains its shape and chemical identity in extreme heat, so super refractories are used in Industries for heat resistance.
