Abstract

Buluş, sıcak daldırma yöntemi ile metallerin üzerine metalik kaplamaların gerçekleştirildiği proseslerde şerit/parça yüzey enerjisini düşürecek ince film bir kaplamanın sıcak daldırma aşaması öncesinde uygulanması ve tek yüzeyi kaplanmış malzeme elde edilmesine olanak sağlayan bir tek yüzey kaplama üretim metodu ile ilgilidir. Gereksiz kaplama tüketimini azaltacağı için maliyet tasarrufu sağlanacağı gibi ergitme için harcanan enerjinin azalması da sağlanarak daha çevreci bir kaplama yöntemi artmasına da olanak sağlamaktadır.The invention relates to a single surface coating production method that allows the application of a thin film coating, which will reduce the surface energy of the strip/piece, before the hot-dip step, in processes where metallic coatings are carried out on metals with the hot-dip method and to obtain a single-surface coated material. As it will reduce unnecessary coating consumption, cost savings will be achieved and a more environmentally friendly coating method will also be increased by reducing the energy spent for melting.

Description

TARIFNAME TEK YÜZEY KAPLAMA YÖNTEMI ILE METALLERIN KAPLANMASI IÇIN YONTEM Teknik Alan Bulus, sicak daldirma yöntemi ile metaller üzerine metalik kaplamalarin gerçeklestirildigi proseslerde serit/parça yüzey enerjisini düsürecek ince film bir kaplamanin sicak daldirma asamasi öncesinde uygulanmasi ve tek yüzeyi kaplanmis malzeme elde edilmesine olanak saglayan bir tek yüzey kaplama üretim metodu ile Teknigin Bilinen Durumu Çinko kapli malzemelerin kullanildigi en büyük pazarlardan birisi olan otomotiv sektöründe de çogu parçada tek yüzeyde korozyon dayanimina ihtiyaç duyulsa da bu özelliklere sahip malzeme olmadigi için her iki yüzeyi de kapli malzemeler kullanmaktadir. Böylelikle gereksiz çinko sarfiyati gerçeklesmektedir. Tek yüzeyi kaplanmis serit üretimi baslangiç yatirim maliyeti oldukça yüksek farkli yollarla saglanabilmektedir. Bu metotlarin özetleri asagida verilmistir. Bu çerçevede bakildiginda bulus kapsaminda gelistirilecek yöntem kompleks olmayan, pratik, hizli ve kolay uygulanabilir olup baslangiç yatirim maliyeti düsüktür. Yapilan literatür arastirmasinda "Tek Tarafli Sicak Daldirmali Kaplama Islemi" baslikli US4254158A yayin numarali basvuruya rastlanmistir. Bu patent dokümani, seridin alt yüzeyine eriyik haldeki çinkoyu püskürterek tek yüzeyin galvaniz kaplanmasiyla ilgilidir. Bu yöntem, farkli serit, pota ve püskürtme açilari ile de uygulanabilmektedir. Yöntemde banyo hareketliligi yüksek oldugundan cüruf olusumunu minimum düzeye indirmek ve yüzey kusurunu azaltmak için çinko banyosu hava ortamindan bagimsiz hale getirilmistir. Önceki teknige ait yapilan patent arastirmasinda rastlanan bir baska basvuru ise "Tek Tarafli Galvanizli Sac Malzeme Üretme Süreci" baslikli US4120997A yayin numarali patenttir. Bu bulus, öncelikli olarak mevcut çift yüzey kaplama üretim prosesinde oldugu sekilde kaplama yapilmakta devaminda ise galvaniz kaplama seridin bir yüzeyinden siyirici firçalar ile kaldirilmaktadir. Bu proseste ilgili mekanik kaldirma islemine uygun serit yüzeyi elde edebilmek için Fe-Zn intermetalik fazlarinin olusumu tesvik edilmektedir. Kaplama banyosu sonrasi GA ürün üretimine benzer sekilde kaplamasi kaldirilacak yüzey kirilgan ve abrasif asinmaya uygun Fe-Zn intermetaliklerinin olusturulabilmesi için 500-800°C'de yaklasik 10 saniye tutulurken, diger yüzeyde çinko kaplamanin elde edilebilmesi için 150°C`ye hizlica sogutulur. Önceki teknige ait yapilan literatür arastirmasinda "Manufacturing of One-side Galvanized and Galvannealed Steel Sheet by Masking Coat" isimli Kawasaki Steel makalesine rastlanmistir. Bu makalede galvaniz kaplama öncesinde seridin bir yüzeyi roll coater yardimiyla seramik bazli kaplamalar ile kaplanir. Bu kaplamayi kürlemek için non-oxidizing firin ve redükleyici firin ortamlarina ihtiyaç duyulmaktadir. Galvaniz banyosundan çikan seridin seramik kapli yüzeyine isitma uygulanarak çinko viskozitesi düsürülmekte hava biçagiyla kolayca siyirilarak galvaniz banyosuna geri dönmesi saglanmaktadir. Bir sonraki adimda ise merdaneler ile mekanik olarak serit yüzeyindeki seramik film kirilarak nihai üründen uzaklastirilmaktadir. Bulusun çözümünü Amaçladigi Teknik Problemler Mevcut bulus, sicak daldirma yöntemi ile metal malzemeler üzerine metalik kaplamalarin gerçeklestirildigi proseslerde serit/parça yüzey enerjisini düsürecek ince film bir kaplamanin sicak daldirma asamasi öncesinde uygulanmasi ve tek yüzeyi kaplanmis malzeme elde edilmesine olanak saglayan bir tek yüzey çinko kaplama Otomotiv sektörü, insaat sektörü ya da genel uygulama alanlari gibi daha çok tek yüzeyde korozyon direnci ihtiyaci olan kullanicilar için piyasada olmayan daha avantajli yeni ürün saglanmasi hedeflenmistir. Bulusun çözümünü amaçladigi problemlerden biri, ihtiyaç duyulmayan yüzeyin kaplanmasidir. Bu problemden ötürü, agirlik degeri de artmaktadir. Bulus, endüstride ihtiyaç duyulmayan yüzeyde kaplama kullanilmayacagi için, tek yüzey kaplama ile totalde agirlik avantaji da saglanmaktadir. Bulusun çözümünü amaçladigi bir diger problem; gereksiz kaplama ile birlikte tüketimlerin artmasi, enerji kaynaklarinin gereksiz harcanmasi ve çevre duyarliligidir. Bulus sayesinde gelistirilecek yöntemin uygulamasi basit ve baslangiç yatirim maliyeti düsüktür. Ayrica gereksiz kaplama tüketimini azaltacagi için maliyet tasarrufu sagladigi gibi ergitme için harcanan enerjinin azalmasina ve çevre duyarliliginin artmasina da olanak saglamaktadir. Sekillerin Agiklanmasi Sekil 1: Yöntemin Akis Semasi Bulusun Açiklamasi Bu açiklamada, tek yüzey kaplama yöntemi sadece konunun daha iyi anlasilmasina yönelik olarak ve hiçbir sinirlayici etki olusturmayacak sekilde açiklanmaktadir. Bulus, tek yüzey kaplama ile ilgili bir yöntemle ilgilidir. Bor nitrit, oksit içermeyen, sentetik olarak üretilmis BN kimyasal formülüne sahip seramik maddedir. Fiziksel ve kimyasal özelliklerinden dolayi seramik alaninda yogun kullanim alani bulur. Dökümhanelerde etkin olarak kullanilan bor nitridin en önemli özelligi alüminyum, magnezyum veya bakir gibi metal eriyikleri islatmamasidir. Bor nitrit iki modifikasyonda olusur. Hegzagonal bor nitrit (h-BN), grafit yapisinda olup yüksek sicaklikta borik oksidin nitrürlenmesi ile elde edildigi bilinmektedir. Kübik bor nitrit ise hegzagonal bor nitrürün yüksek basinç ve sicaklikta islenmesi ile olusturulur. Kübik bor nitrit oldukça sert olup elmastan sonra sertligi en yüksek ikinci malzeme olarak tanimlanmistir ve asinma yüzeyleri ve sertlik özelligi talep edilen özel kullanim alanlari için tercih edilmesi uygundur. Hegzagonal bor nitridin ise kendi kendini yaglama özelligi, oksidasyon direnci, elektriksel ve termal stabilitesi, metal ergiyikler tarafindan islanmamasi en belirgin özellikleridir. Bu çalismada hegzagonal bor nitridin yüksek sicakliklarda malzeme yüzey enerjisi üzerinde olan etkisi kullanilacak ve kaplamasi yapilacak sivi ergiyigin (Zn, Al, Mg, Si ve alasimlari) yüzey yapismasi önlenecektir. Bor nitrit çözeltisi, 900"C'ye kadar stabilitesini koruyabilmektedir. Hegzagonal bor nitrit, çogu metalin ergiyigine karsi uygulandigi yüzeyde islatma enerjisini düsürmektedir. Yani metal ergiyigi ile yüzey arasinda 90°'nin üzerinde islatma açisi olusmasina sebep olmaktadir. Bor nitrit çözeltisi, bulus konusu yöntemde sicak daldirma yöntemiyle parça kaplama yapan tesislerde de kaplama önleyici olarak kullanilabilecektir. Sicak daldirma ile kaplama yöntemi sürekli hatlarda yapilabildigi gibi parça kaplamanin gerçeklestirildigi tesislerde de kullanilmaktadir. Sürekli hatlar kabaca, sirasiyla; temizleme, firin, sogutma ve sicak daldirmanin gerçeklestigi pota bölümlerinden olusmaktadir. Kontrollü atmosfer ortami olan firin bölümünde elektrik, indüksiyon, radyan tüp, dogrudan yanma/yakma yöntemleri ile isitma gerçeklestirilebilmektedir. Isitma ve/veya sogutma adimlarindan sonra isil islemi tamamlanan malzeme sicak daldirma yöntemi ile ergiyik metal banyosuna daldirilir. Malzemenin firindan pota bölgesine geçisi asamasinda hava ile temasini önlemek, oksit ve kirlilik olusumunu en aza indirmek amaciyla köprü görevi gören snout bölümü bulunmaktadir. Kaplama prosesi için çok önemli bir adim olan bu bölge malzemenin sicak daldirma prosesi sonrasi kaplama kalitesine dogrudan etki eder. Snout bölgesinde kontrollü atmosfer ortaminin saglanabilecegi sistemler bulunmaktadir. Snout içerisinde ya da firin ile snout bölgesi arasinda, serit sivi ergiyik potasina girmeden önce kaplanmasi istenmeyen yüzeye (alt ya da üst) alkol bazli bor nitrit püskürtülecek ve bir yüzey kaplanmadan üretim saglanabilecektir. Bor nitrit çözeltisi; parça kaplamalar için daldirma prosesinden önce, seridin tavlamasi ve kaplamasi yapilan sürekli hatlar için firin ile snout bölgesi arasinda ya da snout bölgesinde kaplanmasi istenmeyen parça ya da serit yüzeyine 0,1-10 g/cm2 olacak sekilde uygulanir. Sürekli tavlama hatlarinda sprey yöntemi ile kaplanmasi istenmeyen yüzeye bor nitrit uygulandiktan sonra serit kontrollü bir sekilde ergiyik metal banyosuna daldirilir. Sürekli hattin performans ve yeterliligine bagli olarak 4-16 saniye arasinda serit ergiyik metal banyosunda kalir.

Known State of the Technique with the surface coating production method. In the automotive industry, which is one of the largest markets where zinc coated materials are used, most parts require corrosion resistance on a single surface, but since there are no materials with these properties, materials coated on both surfaces are used. Thus, unnecessary zinc consumption occurs. Single-surface coated ribbon production can be achieved in different ways, with a very high initial investment cost. Summaries of these methods are given below. When viewed in this context, the method to be developed within the scope of the invention is uncomplicated, practical, fast and easily applicable, and the initial investment cost is low. In the literature research, an application titled "One-Sided Hot Dip Coating Process" with publication number US4254158A was found. This patent document is about galvanizing a single surface by spraying molten zinc on the lower surface of the strip. This method can also be applied with different strips, crucibles and spray angles. Since the bath mobility is high in the method, the zinc bath is made independent from the air environment in order to minimize slag formation and reduce surface defects. Another application found in the patent research on the prior art is the patent with publication number US4120997A titled "Process of Producing Single-Sided Galvanized Sheet Material". This invention is primarily coated as in the existing double surface coating production process, and then the galvanized coating is removed from one surface of the strip with scraper brushes. In this process, the formation of Fe-Zn intermetallic phases is encouraged in order to obtain a strip surface suitable for the relevant mechanical lifting process. Similar to the GA product production after the plating bath, the surface to be coated is kept at 500-800°C for approximately 10 seconds to form Fe-Zn intermetallics that are brittle and suitable for abrasive wear, while it is quickly cooled to 150°C to obtain the zinc coating on the other surface. In the literature research on the previous technique, a Kawasaki Steel article titled "Manufacturing of One-side Galvanized and Galvannealed Steel Sheet by Masking Coat" was found. In this article, before galvanizing, one surface of the strip is coated with ceramic-based coatings with the help of a roll coater. Non-oxidizing oven and reducing oven environments are needed to cure this coating. By applying heating to the ceramic coated surface of the strip coming out of the galvanizing bath, the zinc viscosity is reduced and it is easily scraped with an air knife and returned to the galvanizing bath. In the next step, the ceramic film on the strip surface is broken mechanically with rollers and removed from the final product. Technical Problems the Invention Aims to Solve The present invention is based on the application of a thin film coating that will reduce the strip/piece surface energy before the hot dipping stage in processes where metallic coatings are made on metal materials by the hot dipping method, and a single surface zinc coating that allows a single surface coated material to be obtained. Automotive industry It is aimed to provide a more advantageous new product that is not available on the market for users who need corrosion resistance on a single surface, such as the construction industry or general application areas. One of the problems that the invention aims to solve is the covering of unneeded surfaces. Due to this problem, the weight value also increases. Since the invention does not use coating on surfaces that are not needed in the industry, a total weight advantage is also achieved with a single surface coating. Another problem that the invention aims to solve is; Increased consumption with unnecessary coating, unnecessary consumption of energy resources and environmental sensitivity. Thanks to the invention, the method to be developed is simple to implement and has a low initial investment cost. In addition, it provides cost savings by reducing unnecessary coating consumption, as well as reducing the energy spent on melting and increasing environmental awareness. Explanation of Drawings Figure 1: Flow Diagram of the Method Description of the Invention In this explanation, the single surface coating method is explained only for a better understanding of the subject and in a way that does not create any limiting effect. The invention relates to a method for single surface coating. Boron nitride is an oxide-free, synthetically produced ceramic material with the chemical formula BN. It finds extensive use in the field of ceramics due to its physical and chemical properties. The most important feature of boron nitride, which is used effectively in foundries, is that it does not wet metal melts such as aluminum, magnesium or copper. Boron nitride occurs in two modifications. Hexagonal boron nitride (h-BN) has a graphite structure and is known to be obtained by nitriding boric oxide at high temperatures. Cubic boron nitride is formed by processing hexagonal boron nitride at high pressure and temperature. Cubic boron nitride is very hard and has been defined as the second highest hardness material after diamond, and it is suitable for wear surfaces and special usage areas where hardness properties are requested. The most distinctive features of hexagonal boron nitride are its self-lubricating property, oxidation resistance, electrical and thermal stability, and not being wetted by metal melts. In this study, the effect of hexagonal boron nitride on the material surface energy at high temperatures will be used and the surface adhesion of the liquid melt (Zn, Al, Mg, Si and their alloys) to be coated will be prevented. Boron nitride solution can maintain its stability up to 900"C. Hexagonal boron nitride reduces the wetting energy on the surface where it is applied against the melt of most metals. In other words, it causes a wetting angle of over 90° between the metal melt and the surface. Boron nitride solution is the subject of the invention. It can also be used as a coating inhibitor in facilities that coat parts by hot dipping method. Hot dip coating method can be done in continuous lines as well as in facilities where part coating is carried out. Continuous lines roughly consist of crucible sections where cleaning, furnace, cooling and hot dipping take place, respectively. Controlled In the furnace section, which has an atmospheric environment, heating can be achieved by electricity, induction, radiant tube, direct combustion/combustion methods. After the heating and/or cooling steps, the material whose heat treatment is completed is immersed in the molten metal bath with the hot immersion method. During the transition of the material from the furnace to the crucible area, the material does not come into contact with air. There is a snout section that acts as a bridge to prevent and minimize oxide and pollution formation. This region, which is a very important step for the coating process, directly affects the coating quality of the material after the hot dipping process. There are systems that can provide a controlled atmosphere in the snout area. Alcohol-based boron nitride will be sprayed on the surface (bottom or top) that is not wanted to be coated within the snout or between the furnace and the snout area, before the strip enters the liquid melt pot, and production can be achieved without coating a surface. Boron nitride solution; Before the dipping process for part coatings, it is applied at a rate of 0.1-10 g/cm2 to the surface of the part or strip that is not wanted to be coated, between the furnace and the snout zone for continuous lines where the strip is annealed and coated, or in the snout zone. In continuous annealing lines, after boron nitride is applied to the surface that does not want to be coated by spray method, the strip is immersed in the molten metal bath in a controlled manner. Depending on the performance and adequacy of the continuous line, the strip remains in the molten metal bath for between 4-16 seconds. For piece coating, the parts coming out of the molten metal bath are left to cool freely to complete the solidification in the coating area, while in continuous lines, the targeted coating thickness is achieved by using air knives to adjust the coating thickness on the coated surface of the strip at the exit of the plating bath. In both the part coating and continuous strip coating processes, the material coming out of the molten metal bath is cooled in a conditioned environment or by free cooling. For piece coatings, final surface treatments are carried out or temper rolling is applied in line with the mechanical and surface properties of the strip in continuous hot-dip coating facilities. Alternatively, after the coating is annealed to alloy with iron after the continuous hot dipping method, temper rolling is applied in line with the mechanical and surface properties of the strip. For zinc coatings, the application temperature of boron nitride spray may also vary in cases where the entry temperature of the strip or part into the liquid zinc crucible varies between 450 and 550°C. However, the fact that boron nitride does not react with the material or liquid melt on which it is applied allows it to be applied in a very wide temperature range. Boron nitrite can be applied at the beginning of the snout zone or at the exit of the furnace zone between 400-650°C, or at higher temperatures in the furnace zone (650-850°C), or after the furnace inlet cleaning section. Within the scope of the invention, it has been determined that the most suitable application is achieved at the exit of the oven and the entrance of the snout zone. Boron nitride solution prepared with alcohol-based solvents is applied to the strip surface at a rate of 0.1-10 g/cm2. Alumina or silica-based binder can be used in the solution, and it must contain at least 7% boron nitride. In the method of the invention, boron nitride is applied to hot substrate materials with high surface area by spraying with pressurized nitrogen or argon gas. Because in order to obtain the best coated surface properties in the hot dipping process, the material to be coated by the dipping method must be at a temperature of plus or minus 50 °C with the molten metal temperature in the crucible. In this case, the strip temperature for zinc coatings should vary between 350-600 oC. Air pressurized spray application of the substrate material at high temperatures will increase the amount of oxidation on the surface. Pressurization should be done with nitrogen or argon gas to prevent unwanted oxide layers on the surface before final use. Although this invention is mainly based on single-surface zinc-coated strip production in the iron and steel industry, it can also be used in many hot-dip coating methods.
