White fused alumina (WFA) plays a critical role in steel ladle furnaces (SLF) as a high-performance refractory material, primarily used in linings and functional components to withstand harsh operating conditions. Its core functions revolve around protecting the furnace structure, ensuring steel quality, and extending service life, with specific roles detailed below: 1. Refractory Lining for

Measuring the ball milling toughness of white fused alumina (WFA) is standardized by national/international protocols, focusing on quantifying its resistance to fragmentation during ball milling. Here’s a step-by-step guide based on core standards like GB/T 2479-2022 (China) and relevant industrial practices: 1. Core Test Standard & Principle Reference Standard: Primarily GB/T 2479-2022 Abrasive—White Fused Alumina (China) or

  White fused alumina was made from the high quality alumina by melting above 2200℃ in the electric arc furnace and cooling. White fused alumina is white with the main crystal phase alpha-Al2O3. White fused alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume

Fixed furnace white corundum and dumping furnace white corundum differ in the following aspects:   Production process Fixed furnace: In the production of fixed furnace white corundum, the raw materials are placed in a fixed furnace for smelting. After smelting, the furnace body does not move, and the corundum is cooled and solidified in the

Yes, white corundum can be used for sandblasting high-speed steel (HSS) products, but its application requires careful matching with the material properties of HSS (high hardness, high toughness, often used for precision components like cutting tools and molds) and sandblasting objectives (e.g., removing oxide scales, deburring, or surface roughening for pretreatment). The right type, grit size,

We are china supplier white fused alumina refractory grade abrasives grade WFA manufacturer. We start our plant since 1999 year. We are focus in white fused alumina refractory grade and abrasives grade We do export business since 2010 year. We can supply all available sizes in refractory application & Abrasives application FEPA macrogrit,microgrit.JIS powder.  

Bulk density of white fused alumina/white corundum/white electrocorundum/white alundum/WFA Two KEY point determine the bulk density level.  Content of NA2O,lower Na2O level alumina powder can produce higher alpha crystal AL2O3,then density will be higher,because BeTA alumina density is much lower than Alpha alumina. Melting technology also an big reason for porosity,lower porosity rate can support

The whiteness data of white fused alumina/corundum/aluminum oxide For your reference,our   white fused alumina/corundum/aluminum oxide granule’s whiteness can reach to 85-90. Available size F120 F150 F180 F220. See picture below.
