Description

Przedmiotem wynalazku jest okladzina stalowa walców szarpiacych w przedzarkach przedzacych metoda wolnego konca, które to walce posiadaja beben i stalowy drut pilowy nieruchomo osadzony na tym bebnie jako okladzine. ¦ Okladzina walców szarpiacych w przedzarkach ulega szybkiemu zuzyciu. Czesto zywotnosc jednej okladziny przy przeróbce wlókien sztucznych wynosi zaledwie dwa tygodnie. Dotychczas starano sie przedluzyc zywotnosc okladzin calkowicie stalowych walców szarpacza przez zastosowanie stali martenzytycznych cwysokiej wytrzymalosci jako materialu drutu pilowego,, Mimo zastosowania takich srodków nie udalo sie przedluzyc zywotnosci ponad wyzej podany okres* Celem wynalazku jest opracowanie okladziny o zywotnosci znacznie wiekszej niz dotychczas stosowane.The subject of the invention is the steel cladding of jerking rolls in the cutting process free end, the rolls having a drum and a steel saw wire fixed to the drum as cladding. ¦ The cladding of the jerking rolls in the clearing cuts is subject to rapid wear. Often the life span of one Cladding when processing artificial fibers is only two weeks. So far, efforts have been made Extend the life of the full steel linings of the chopper rollers by using steel high strength martensitic materials as saw wire material, despite the use of such The funds were not able to extend the life beyond the above-mentioned period * The aim of the invention is to provide a cladding with a service life that is much longer than that used so far.

Cel ten osiagnieto dzieki temu, ze okladzina wykonana jest ze stali chemicznie odpornej. Korzystnym jest wykonanie okladziny ze stali zawierajacej co najmniej 12% chromu lub tez ze stali austenitycznej chromo-niklowej. Przeprowadzone badania wykazaly, ze korzystnym jest dodawanie do stali molibdenu.This goal was achieved due to the fact that the cladding is made of chemically resistant steel. It is favorable making the cladding of steel with at least 12% chromium or also of austenitic steel chrome-nickel. The tests performed have shown that adding molybdenum to the steel is advantageous.

Szczególnie korzystnym jest gdy okladzina wykonana jest ze stali austenitycznej z zawartoscia 12 do 19% chromu, 7 do 15% niklu i 2 do 3% molibdenu.It is particularly advantageous when the cladding is made of austenitic steel with a content of 12 to 19% chromium, 7 to 15% nickel and 2 to 3% molybdenum.

Przeprowadzone badania wykazaly, ze chemicznie odporne stale austenityczne wykazuja przy przeróbce wlókien syntetycznych znacznie wieksza zywotnosc niz okladziny wykonywane dotychczas ze stali o wysokiej wytrzymalosci.The tests carried out showed that chemically resistant austenitic steels showed during processing synthetic fibers have a much longer service life than the linings previously made of high steel endurance.

Przeprowadzono próbe porównawcza z walcem szarpiacym, którego calkowicie stalowe obicie mialo drut pilowy ze stali weglistej o twardosci Rockwella od 60 do 64. Ten walec szarpiacy zostal zastosowany do przerobu wlókien akrylu. Po 160 godzinach pracy pokazaly sie na przednich krawedziach zebów rowki i dziury na skutek czego calkowicie stalowe obicie nie nadawalo sie do dalszego uzytku po takim okresie pracy. Przy dalszej pracy okazalo sie, ze zeby zostaly prawidlowo odpilowane. Nastepnie przeprowadzono druga próbe ze stala chromowo-niklowa o zawartosci chromu od 17 do 19% i zawartosci niklu od 8 do 10% i z zawartoscia wegla nizsza od 0,12%. Drut pilowy wykonany z tego materialu zostal po procesie walcowania poddany obróbce cieplnej przy temperaturze 1100°C i zaraz potem szybko schlodzony w wodzie dla uzyskania lepszej struktury2 94 509 ziarn. Do szarpacza dano do przerobu ponownie wlókno akrylu i to na okres pracy 500 godzin. Po tym okresie pracy na zebach nie byly jeszcze widoczne jakiekolwiek zmiany, tak ze próbe przerwana « Zastosowana stal chromowo-niklowa jest w porównaniu ze stala weglista zastosowana, w pierwszym przykladzie wzglednie miekka, poniewaz tego materialu nie mozna praktycznie zahartowac. Pomimo tego uzyskano wielokrotne przedluzenie okresu zywotnosci obicia. Z. tego mozna wyciagnac wniosek, ze zywotnosc nie tyle zalezy od twardosci zastosowanego rodzaju stali, co od jej chemicznej odpornosci. Stanowi to przeciwstawienie dotychczasowych staran przedluzenia zywotnosci . okladzin walców szarpiacych przez podwyzszenie twardosci stali. Jakkolwiek te dotychczas przedsiebrane srodki dawaly przedluzenie zywotnosci okladzin, to mozna bylo ja bardzo znacznie przedluzyc przez zastosowanie srodków wedlug wynalazku.A comparative test was carried out with a jerking roller, the complete steel covering of which had a wire carbon steel saw blade with a Rockwell hardness of 60 to 64. This jerking roller has been used for processing acrylic fibers. After 160 hours of operation, grooves and holes appeared on the front edges of the teeth as a result, the all-steel upholstery was not suitable for further use after such a period of work. At further work, it turned out that they were properly trimmed. Then a second trial with chromium-nickel steel with a chromium content of 17 to 19% and a nickel content of 8 to 10% and a carbon content less than 0.12%. The saw wire made of this material was processed after the rolling process heat at 1100 ° C and then quickly cooled in water to obtain a better structure grains. The acrylic fiber was re-processed into the chopper for a period of 500 hours. After this period working on the teeth no changes were visible yet, so that the attempt was interrupted « The chrome-nickel steel used is compared to the carbon steel used in the first For example, it is relatively soft because the material cannot be practically hardened. Despite this a multiple extension of the life of the upholstery was obtained. From this it can be concluded that the viability it does not so much depend on the hardness of the type of steel used, but on its chemical resistance. It represents opposition to previous efforts to extend the life span. cladding of jerking rollers increasing the hardness of steel. However, these hitherto prepared measures resulted in an extension of the life span cladding, it could be very significantly extended by using the measures according to the invention.

To korzystne oddzialywanie wystepuje juz przy zastosowaniu prostych stali chromowych. Jednak korzystniej jest zastosowac stale chromowo-niklowe, które sa szczególnie odporne na korozje. Tego rodzaju stale chromowo-niklowe posiadaja zawartosc chromu w ilosci okolo 18% i zawartosc niklu 8%, jednak dla dalszego ulepszenia odpornosci chemicznej moga byc zastosowane stale bardziej wysoko-stopowe i zawierajace jeszcze dalsze skladniki stopowe, jak na przyklad molibden, tytan i niob. » Mozna równiez zastosowac utwardzone dyspersyjnie stale nierdzewne, które na ogól posiadaja dodatek glinu. 'This favorable interaction already occurs with the use of simple chrome steels. However it is more preferable to use chromium-nickel steels which are particularly resistant to corrosion. That kind of constantly chrome-nickel have a chromium content of about 18% and a nickel content of 8%, but for further Chemical resistance improvements can be applied steels more high-alloyed and containing more further alloying elements, such as, for example, molybdenum, titanium and niobium. » Case-hardened stainless steels, which generally have an additive, can also be used aluminum.
