Abstract
Bir çelik telin üretilmesine yönelik proses bu adımları içerir: bir çelik telin sağlanması; söz konusu çelik telin ostenitlenmesi; söz konusu çelik telin patentlenmesi; söz konusu çelik telin çekilmesi. Söz konusu çelik telin patentlenmesi bu adımları içerir: söz konusu çelik telin birinci bir önceden belirlenen sıcaklığa yavaş soğutulması; çelik telin ikinci bir önceden belirlenen sıcaklığa hızlı soğutulması; söz konusu çelik telin söz konusu ikinci önceden belirlenen sıcaklıkta tutulması. Yavaş soğutma sırasında çelik tel, ostenit yapısını büyük ölçüde değişmeden korur; sonraki hızlı soğutma ile çelik tel, ostenit yapısının bir perlit yapısına dönüştürüldüğü faz değişimini başlatmak amacıyla en iyi koşullara getirilir.The process for producing a steel wire comprises these steps: providing a steel wire; austenitizing said steel wire; patenting said steel wire; drawing said steel wire. Patenting said steel wire includes these steps: slow cooling said steel wire to a first predetermined temperature; rapid cooling of the steel wire to a second predetermined temperature; keeping said steel wire at said second predetermined temperature. During slow cooling, the steel wire retains the austenite structure substantially unchanged; with subsequent rapid cooling, the steel wire is optimized to initiate the phase change in which the austenite structure is converted to a perlite structure.
Description
Tarifnamenin geri kalaninda, ostenit terimi ayrica, temel olarak tamamen ostenit bir yapiya sahip olan çelige refere etmek üzere, perlit terimi temel olarak tamamen perlitli bir yapiya sahip çelige refere etmek üzere kullanilacaktir. Throughout the remainder of the specification, the term austenite is also used mainly entirely The term perlite is basically used to refer to steel with an austenite structure. will be used to refer to steel with a completely perlite structure.
Patentleme sirasinda çelik telin yapisinin ostenitten (gama demirindeki karbonun sert solüsyonu) perlite (ferritin ve sementinin ince tabakasindan olusturulan) istenen faz transformasyonu, baslangiç sogutmasinin yeterince soguk oldugu sürece gerçeklestirilir; aksi takdirde ostenit, perlite degil, beynite (ferrit ve sementitin veya kompleks karbütlerin parçaciklari ile olusan igne biçimli kümeler) dönüsür, bu, bir sonraki çekme için uygun olmamasi nedeniyle istenmeyen bir çelik yapisidir: bu durum, çekme sonrasindaki çelik telin mekanik özelliklerinin, bunun yapisinin önemli bir miktar beynit içermesi durumunda optimal olmadigi anlamina gelir. At the time of patenting, the structure of the steel wire was made from austenite (the carbon in gamma iron is hard. solution) perlite (formed from a thin layer of ferritin and cementum) desired phase transformation, as long as the initial cooling is cold enough. is carried out; otherwise austenite, not pearlite, but bainite (ferrite and cementite or needle-shaped clusters formed by particles of complex carbides), which is a is an undesirable steel structure as it is unsuitable for subsequent drawing: The mechanical properties of the steel wire after drawing play a significant part in its structure. If it contains bainite, it means that it is not optimal.
Bunun aksine basvuru sahibi, çok hizli bir sogutma elde etmeye çalismanin gerçekte, telde ostenit-perlit dönüsümündeki istenen mikro yapiyi elde edebilen sicakligin dogru bir biçimde ortadan kaldirilmasindaki dogal zorluklar nedeniyle ters tepki yapabilecegini bulmustur. Örnegin ostenitleme sicakliklarindan çok hizli bir sogutma, telin parçasinin yüzeyi ile bir radyal yöndeki iç kisim arasindaki yapisal tekdüzeligin kontrol edilmesini zorlastirir. On the contrary, the applicant believes that trying to achieve a very fast cooling actually means, The correct temperature to obtain the desired microstructure in the austenite-perlite conversion in the wire. that it may react adversely due to the inherent difficulties in eliminating it in some way. has found For example, a very rapid cooling from austenitizing temperatures may occur with the surface of the piece of wire. makes it difficult to control the structural uniformity between the interior in a radial direction.
Basvuru sahibi, bunun yüksek sicaklikta ostenitlemenin ardindan yavasça sogutmaya tabi tutulmasi durumunda, çelik telin ostenitli yapisinin sürdürülmesinin mümkün oldugunu bulmustur. The applicant must allow it to cool slowly after austenitizing at high temperature. it is possible to maintain the austenitic structure of the steel wire found that it was.
Bu nedenle basvuru sahibi, ostenitli yapiyi koruyarak çelik telin sicakliginin yavas bir biçimde düsürülmesinin ve ardindan -çekilmenin ardindan- kusursuz mekanik özelliklere (örnegin yüksek dayaniklilik. yüksek genisleme ve yüksek burulma ve yorulma dayanimi) sahip olan bir tel olusturularak, ostenitten perlite istenen dönüsüm saglanarak basit bir biçimde _düsük baslama sicakligi sayesinde- hizli bir biçimde sogutulmasinin mümkün oldugunu bulmustur. Basvuru sahibi, teli olusturan perlitin temel olarak, parçali bir mikro yapidan çok katmanli bir mikro yapiya sahip oldugunu ve bu tür bir katmanli yapinin ince oldugunu bulmustur; “ince” terimi ile, araliklandirmanin yaklasik 100 nm'den az oldugu katmanli bir mikro yapi ifade edilir. For this reason, the applicant is expected to maintain the austenitic structure at a slower temperature of the steel wire. Perfectly mechanized after being dropped and then pulled properties (e.g. high strength, high expansion and high torsion and the desired conversion from austenite to pearlite simply by providing a _low start temperature- quickly found that it was possible to cool it. Applicant, perlite forming the wire basically, it has a multi-layered microstructure from a fragmented microstructure and found that such a layered structure is thin; With the term “fine”, the spacing Less than about 100 nm is referred to as a layered microstructure.
Basvuru sahibi, bu ince katmanli perlitli mikro yapiya, sonraki çekmeye karsi koyabilen telin daha iyi yeterliligini atfeder. Applicant believes that this thin layered perlite microstructure can resist subsequent shrinkage. attributes better adequacy of the wire.

Basvuru sahibi ayrica, bulusa göre proses ile üretilen teller sayesinde baglama prosesinde önemli bir gelisme elde edebilmistir. Örnegin: 2+1x0.22HT bir kabloya, diger bir deyisle birbirine baglanan yüksek dayanimli çelik ile kaplanan 0.22 mm bir çapa sahip olan üç temel tel tarafindan olusturulan bir kabloya yönelik olarak, klasik patentleme ile üretim için her 150 km'de bir kirilmaya göre, üretilen her 279 km kabloda bir kirilma oldugu bulunmustur. Sonuç olarak üretilen 1000 km kablo için gerçeklestirilecek olan kaynaklarin sayisi, standart 6.7 kaynaklara nazaran 3.6'ya düsmüstür. In addition, the applicant also receives bonding thanks to the wires produced by the process according to the invention. achieved a significant improvement in the process. For example: 2+1x0.22HT high-strength cable connected to each other, in other words. formed by three basic wires having a diameter of 0.22 mm covered with steel for the cable, breaking every 150 km for production with classical patenting According to the results, it was found that there is a break in every 279 km of cable produced. produced as a result The number of welds to be performed for 1000 km of cable corresponds to standard 6.7 welds. compared to 3.6.
Avantajli olarak mevcut bulusa göre çelik bir telin üretilmesine yönelik proses asagidaki adimlari mümkün hale getirir: - son mekanik özellikleri saglarken, düsük bir C içerigi (örnegin %O.8 yerine - büyük ölçüde ayni C içerigine sahip olan, ancak daha az sayida adim ile çekmek veya telin çapinda daha küçük bir azalma ve dolayisiyla bunun daha az sertlesmesini saglamak amaciyla daha küçük olan bir çapa sahip olan bir tellik çubuk ile baslayan bir materyal üzerinde prosesin gerçeklestirilmesi.Advantageously, the process for producing a steel wire according to the present invention is as follows: makes the steps possible: - a low C content (for example instead of 0.8%) while maintaining the final mechanical properties - substantially the same C content, but with fewer steps shrinkage or a smaller reduction in the diameter of the wire and therefore less a wire having a smaller diameter to harden it performing the process on a material that starts with a rod.
