Development of new materials use nano particle additives Actual research of Refmon Dr. Attila Rácz chem. ing. director

Steps of Vibro Casting Refmon technology Weighing and dry mixing Wet mixing Casting and forming Pulling Drying and firing Machining Quality control Packing

Weighing and dry mixing Coarse and fine grains are weighing and mixing to get homogeneous dry mix

Raw materials All shaped materials are conglomerate of different grain size refractory materials Coarse are mm size, fine are micron meter size

Wet mixing Castables making from dry mixes with intensive mixer

Casting Refmon use vibro casting process Under vibration wet mix start to flow

Before vibration

Under vibration

Forming The wet mix is casting in to the mould under vibration In the mould shapes became hard use different binder

Drying From the mould shape is going to drying kiln, to reduce moisture content

Firing

Machining Some products machine

Quality control According application field not only size is controlling but some other different test is making at Refmon labor, as corrosion test with glass, slag and ASTM wear resistant test too.

Packing According costumer inquire ready product is packing in EU palette or in wooden box

New developments Because of nano technology improvement Refmon first of the companies to developed technology use nano additives What is nano size particle? Line of sizes: 1 mm = 1OOO µm 1 µm = 1OOO nano m

Human hair Nano size meshing gears

Traditional product The traditional structure show the following picture On it can see there are many space between the grains Space sizes are nano size

New product structure If we fill with nano particles the structure it will be denser The properties will be better! New structure show the photo

Position of new products wear properties Wear losses in cm3 according ASTM Standard

Conclusion Use specials nano particle not only the mechanical properties but erosion and wear resistant are also better Use new application of development Refmon can produce improved quality of products Result of new generation materials !
