Description

Dear sirs, We are pleased to recommend dense fused alumina to your for refractory application. Dense Fused Alumina is a kind of new refractory raw material, by using high purity alumina and reducing agent in certain ratio, smelting in electric arc furnace and naturally cooled. With a-Al2O3 as main crystalline phase and gray color, DFA is characterized by high melting point, high bulk density, low apparent porosity, excellent wear resistance, slag resistance, stable volume and thermal shock resistance. Therefore it is regarded as an excellent refractory material among corundum series. DFA is the preferred material for producing high performance monolithic and shaped refractories used for iron
