Dense Fused Alumina for Refractory

Dense Fused Alumina for Refractory is a new high-purity refractory material formed by using high-purity alumina and reducing agents in a specific ratio, smelting in an electric arc furnace and cooled. The main crystal phase is α-Al2O3, and the color is light gray. Dense Fused Alumina for Refractory used dense alumina has a high melting point and a high-volume density, which melted at high temperature and constant temperature in an advanced electric melting tilting furnace. DFA is the ideal material for unshaped and shaped refractories, such as tapping trough of blast furnace, castables for ladle, ramming mix, prefabricated parts, extended nozzle, submerged entry nozzle, stopper, porous brick and nozzle seating brick, etc.

Dense Fused Alumina for Refractory(FAQ)

What is mohs hardness?

Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it can scratch the latter. Please note that these values merely form an

What is a silane coating used for?

When functionalising fused alumina, a very thin layer of a silane adsorption group is applied to the fused alumina particles. This organic surface coating has the effect of better embedding and increased scratch resistance in a melamine resin matrix, for example. Fused alumina has a high refractive index (n =

What is the warranty policy?

Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.

What is your terms of payment?

T/T 30% as deposit, and 70% before delivery. We’ll show you the photos of the products and packages .before you pay the balance.

What does the form factor (grain shape) indicate?

The description of the grain shape can range from “angular” to “acicular” to “spherical”. When the value of the dimensionless form factor is 1, the grain is spherical. The smaller the form factor, the pointier the grain.
