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 are the different coated abrasive grain types and their characteristics?
Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. Its applications include aluminum, ferrous metals (including alloy steel), hardwood, and leather. Crocus – Crocus
How do i know what abrasive is best for my application?
An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media Selection Guide to choose the most appropriate abrasive for your application.
What does the term “flow properties” mean?
The flow behaviour of powders depends on many factors. The following applies in general: Coarser, dry grain types flow easily, but the fine the grains get, the stronger is the impact of morphology and various adhesive forces on the flow behaviour: Van der Waals forces Liquid bridges Electrostatic interaction The
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 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 =
