Abstract:
Pri vročem iztiskovanju izdelkov iz aluminija in aluminijevih zlitin je bistvena kvaliteta površine in ustrezna mikrostruktura. Velik pomen za doseganje zahtevane kvalitete ima mazanje. Mažemo lahko orodje ali material - okroglico. V okviru diplomskega dela so bile opravljene raziskave vpliva režima mazanja materiala na kvaliteto površine in mikrostrukturo iztiskancev. Ker se z mazanjem pred iztiskovanjem mazivo prenese na orodje, se na ta način mažejo tudi naslednje palice pri iztiskovanju. Z ustrezno količino maziva in frekvenco mazanja okroglic lahko zagotovimo konstantnost kvalitete površin iztisnjenih palic. To je bil tudi cilj moje diplomskega dela, v katerem sem kot mazivo uporabil keramični sprej SOGELUB MD 2000, katerega osnova je borov nitrid. Rezultati raziskav kažejo, da mazanje ugodno vpliva na kvaliteto površine iztisnjenih palic, mikrostrukturo v površinskem sloju, podaljša življensko dobo orodja in izboljša ekonomičnost proizvodnje.

Title:
Lubrication of tools during hot extrusion of aluminium alloys
Abstract:
In hot extrusion of products made of aluminium and aluminium alloys, the quality of surface and suitability of microstructure are essential. With the intention to reach the requested quality, lubrication is of high significance. In the praxis, tools or extruded material can be lubricated. In the frame of diploma work the influence of lubrication sequence on the surface quality and microstructure has been studied. Because of lubrication the material before extrusion, part of the lubricant is transmitted on the tool and it enables lubrication of the rods, which are next extruded. With the appropriate quantity of lubricant and frequency of lubrication the constant quality of the surface of extruded rods can be assured. This was also the aim of my diploma work where the ceramic spray SOGELUB MD 2000, based on boron nitride, has been used. Results of the research have shown that lubrication is advantageous for the quality of extruded rods and for the microstructure in the surface region. It also increases the live time of tools and improves the production economy.
