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

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

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

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

5. Wet mixing Castables making from dry mixes with intensive mixer

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

7. Before vibration

8. Under vibration

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

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

11. Firing

12. Machining Some products machine

13. 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.

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

15. 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

17. Human hair Nano size meshing gears

18. 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

19. 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

20. Pressure Casting Process Production Slip Mould Production Pressure Casting Drying Fireing Packing

21. Mould production

22. Mould Casting with Resine

23. Slip Test

24. Őressure Slip Casting

25. Slip Production

26. Firing

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

28. 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 !
