Description

Područje tehnike The field of technology

Tehničko rješenje odnosi se na spoj zaokretnog segmenta od čelika koji sadrži mangan s tračnicom od čelika koji sadrži ugljik, naročito zaokretnih dijelova željezničkih i tramvajskih spojeva koji se sastoje od držača razmaka od čelika koji sadrži bainit. The technical solution refers to the connection of a turning segment made of manganese-containing steel with a rail made of carbon-containing steel, especially the turning parts of railway and tram connections consisting of spacers made of steel containing bainite.

Stanje tehnike State of the art

Do sada poznati i korišteni spojevi zaokretnih segmenata, naročito željezničkih i tramvajskih zaokretnih segmenata s tračnicama od čelika koji sadrži perlit, predstavljeni su mehaničkim spojevima koji koriste koljena i vijke velike jačine ili u kombinaciji s koso spojenim izoliranim spojevima. Segmenti spojeni na taj način izmijenjeni su na takav način, tako da se mogu zavariti unutar kolosijeka. Uzevši u obzir različit sastav čelika koji sadrži mangan i potrebnih izmjena topline sa svrhom postizavanja traženih značajki za željezničko i tramvajsko nadgrađe, moguće ih je zavariti neposredno na čelik koji sadrži perlit. Poznati spoj zaokretnih segmenata od čelika koji sadrži mangan također se vrši uz korištenje držača razmaka od čelika koji sadrži austenit s visokim sadržajem Cr i Ni, što omogućava varenje s tračnicama od čelika koji sadrži perlit. Until now, known and used joints of turning segments, especially railway and tram turning segments with rails made of steel containing pearlite, are represented by mechanical joints using elbows and screws of high strength or in combination with diagonally connected insulated joints. The segments joined in this way have been modified in such a way that they can be welded inside the track. Taking into account the different composition of steel containing manganese and the necessary heat changes in order to achieve the required features for railway and tram superstructures, it is possible to weld them directly to steel containing pearlite. The well-known connection of turning segments of steel containing manganese is also made using spacers of steel containing austenite with high Cr and Ni content, which allows welding with rails of steel containing pearlite.

Loša strana mehaničkog spoja zaokretnih segmenata uz korištenje koljena i vijaka velike jačine ili u kombinaciji s koso spojenim spojevima, obuhvaća habanje vijaka i potrebnu zamjenu i – uzevši u obzir različita toplinska širenja spojnog materijala – kidanje spojeva, što loše utječe na željezničke i tramvajske setove. Loše strane zavarivanja zaokretnih segmenata od čelika koji sadrži mangan s tračnicama koje imaju držače razmaka od čelika koji sadrži austenit, s visokim sadržajem Cr i Ni, obuhvaća kopmplicirano zavarivanje materijala, relativno nisku tvrdoću Cr Ni držača razmaka, što dovodi do habanja tračnice na mjestu varenja. The downside of the mechanical connection of pivoting segments with the use of elbows and bolts of high strength or in combination with diagonally connected joints, includes the wear of the bolts and the necessary replacement and - taking into account the different thermal expansion of the joint material - tearing of the joints, which has a bad effect on railway and tram sets. Disadvantages of welding swivel segments of manganese steel with rails having spacers of austenitic steel, high in Cr and Ni, include complicated welding of the material, relatively low hardness of the Cr Ni spacers, which leads to wear of the rail at the weld point .

Bit izuma The essence of invention

Gore navedene loše strane se u velikoj mjeri mogu otkloniti spajanjem zaokretnih segmenata od čelika koji sadrži mangan s tračnicom od čelika koji sadrži ugljik, koja se sastoji od držača razmaka od čelika koji sadrži bainit, što se temelji na činjenici što držač razmaka od čelika koji sadrži bainit ima, izuzev željeza, slijedeći sastav u težinskim postocima: 0,07 do 0,15% ugljika, 0,50 do 1,20% mangana, najviše 0,50% silicijuma, 1,20 do 2,00% kroma, 0,40 do 0,70% molibdena, 2,50 do 3,50% nikla, najviše 0,13% vanadija, najviše 0,05% titana, najviše 0,045% ukupnog sadržaja aluminijuma u čeliku, najviše 0,015% fosfora, najviše 0,015% sumpora. The above disadvantages can be largely overcome by joining the manganese-containing steel pivot segments with the carbon-containing steel rail, which consists of a spacer of steel containing bainite, based on the fact that the spacer of steel containing Bainite has, excluding iron, the following composition in weight percentages: 0.07 to 0.15% carbon, 0.50 to 1.20% manganese, maximum 0.50% silicon, 1.20 to 2.00% chromium, 0 .40 to 0.70% molybdenum, 2.50 to 3.50% nickel, not more than 0.13% vanadium, not more than 0.05% titanium, not more than 0.045% of the total aluminum content of the steel, not more than 0.015% phosphorus, not more than 0.015% sulfur.

Prednosti držača razmaka od bainita u usporedbi sa rješenjem u stanju tehnike obuhvaćaju bolju otpornost na abraziju i veću čvrstoću kojom se otklanja habanje vara. Druga prednost obuhvaća mogućnost, da elementi tračnica prođu kroz zaokretne segmente kod velikih brzina, bez smetnji. The advantages of bainite spacers compared to the prior art solution include better abrasion resistance and greater strength to eliminate weld wear. Another advantage includes the possibility for the rail elements to pass through the turning segments at high speeds, without interference.

Primjer tehničkog rješenja An example of a technical solution

Primjer tehničkog rješenja obuhvaća međuspoj zaokretnog segmenta od čelika koji sadrži mangan prema UIC 866V s tračnicom od čelika koji sadrži ugljik, kvalitete 95 ČSD VK, koja se sastoji od držača razmaka od čelika koji sadrži bainit, što obuhvaća, izuzev željeza – slijedeći sastav u težinskim postocima: 0,14% ugljika, 0,80% mangana, 0,34% silicijuma, 1,76% kroma, 0,471% molibdena, 2,63% nikla, 0,087% vanadija, 0,045% titana, 0,042% ukupnog sadržaja aluminijuma u čeliku, 0,014% fosfora, 0,009% sumpora. An example of a technical solution includes the interconnection of a turning segment made of steel containing manganese according to UIC 866V with a rail made of steel containing carbon, quality 95 ČSD VK, consisting of spacers made of steel containing bainite, which includes, except for iron - the following composition in weight percentages: 0.14% carbon, 0.80% manganese, 0.34% silicon, 1.76% chromium, 0.471% molybdenum, 2.63% nickel, 0.087% vanadium, 0.045% titanium, 0.042% of the total aluminum content in steel, 0.014% phosphorus, 0.009% sulfur.

Za spajanje se koristilo sučeono otporno zavarivanje, gdje se kod prvog vara držač razmaka od čelika koji sadrži bainit spoji sa zaokretnim segmentom od čelika koji sadrži mangan ili spojnom tračnicom od čelika koji sadrži ugljik, a nakon skraćivanja držača razmaka koji sadrži bainit na duljinu od 50 mm, držač razmaka se drugim varom spoji sa suprotnim segmentom, tj. spojnom tračnicom od čelika koji sadrži ugljik ili zaokretnim elementom od čelika koji sadrži bainit. Uzajamnim taljenjem materijala koji se vare, u spoju ostaje držač razmaka od čelika koji sadrži bainit duljine 35 mm. For the connection, butt resistance welding was used, where in the first weld, a spacer holder made of steel containing bainite is connected to a swivel segment made of steel containing manganese or a connecting rail made of steel containing carbon, and after shortening the spacer holder containing bainite to a length of 50 mm, the distance holder is connected by another weld to the opposite segment, i.e. a connecting rail made of steel containing carbon or a swivel element made of steel containing bainite. By mutual melting of the materials to be welded, a distance holder made of steel containing bainite of length 35 mm remains in the joint.

Zavarivanje zaokretnih segmenata od čelika koji sadrži mangan s tračnicama od čelika koji sadrži ugljik može se dobro koristiti za proizvodnju željezničkih i tramvajskih zaokretnih segmenata s ozbiljnim zahtjevima na jačinu i otpornost zavarenih segmenata. The welding of manganese-containing steel turning segments with carbon-containing steel rails can be well used for the production of railway and tramway turning segments with serious requirements on the strength and resistance of the welded segments.
