Aluminothermic process

Such metals and alloys include the reactive metals chromium niobium tantalum molybdenum and vanadium as well as refractory metals such as tungsten It is an important feature of many aluminothermic reductions that the high exothermic heat of reaction permits the raising of the slag and metal phases to above their melting points and thus avoids the need for any added heat.

aluminothermic reduction process for chromium ore

19.07.2020  Aluminothermic process Atomic Energy Board Oct 02 1979 The conventional aluminothermic reduction is essentially a batch process One finds in practice that recoveries of metal from slag are not uniformly good due to the short time available for reaction and the short time that the slag and metal phases are in the molten state and during which time separation must take place.

What Is Chromate Conversion Coating with picture

Chromium metal coatings were found to reduce corrosion to acceptable levels A chromate conversion coating is often called a chemical film and the coating layer is quite thin unlike paint or zinc plating One advantage of chromate coatings is their ability to self heal small imperfections rubs or scratches The chromium atoms can move slowly in the coating layer and will eventually re coat
