Pirinç alasimindan mamül ürünlerin üretiminde en çok kullanilan yöntemlerden biri düsük basinçli döküm teknigidir. Bahsedilen yöntemle üretilen nihai ürünün özellikleri pirincin eriyik haldeki sicakligi, eriyigin sekillendirilmek üzere aktarildigi kalibin sicakligi, bu kaliba aktarilma basinci, aktarilma ivmesi, aktarilma zamani, kalip içinde dagilimi ve nihai halini almak üzere kalipta bekletilme süresi gibi proses kosullari iliskilidir. Üretilen nihai ürünün özellikleri ayni zamanda her kaliplama isleminin ardindan sogutulmak üzere sogutma havuzuna daldirilan kaliplarin bahsedilen havuza daldirilma süresi, bu havuzda bekletilme süresi, bu havuzun bilesimi ve sicakligi ile de iliskilidir. Dolayisiyla döküm prosesinde karsilasilabilecek problemlerin engellenmesi amaciyla proses kosullarinin sürekli kontrol altinda tutulmasi gerekmektedir. One of the most used methods in the production of products made of brass alloy pressure casting technique. Characteristics of the final product produced by the aforementioned method state temperature, the temperature of the mold where the melt is transferred to be shaped, the temperature of transfer to this mold pressure, transfer acceleration, transfer time, distribution in the mold and to take its final form. Process conditions such as holding time in the mold are related. The properties of the final product produced are the same. immersed in the cooling pool to be cooled after each molding process. the immersion time of the molds in the said pool, the waiting time in this pool, It is also related to its composition and temperature. Therefore, it can be encountered in the casting process. Keeping the process conditions under constant control in order to prevent problems required.
Pirinç alasimindan mamül ürünlerin düsük basinç döküm yöntemiyle üretimi sirasinda alasim özelliklerinde veya üretim sonrasinda nihai ürün özelliklerinde meydana gelen istenmeyen degisimlerin yarattigi problemler, nedenleri ayrintili olarak incelenmeden, döküm basinci, döküm ivmesi, eriyigin kalipta bekleme süresi, kalibin sogutuldugu havuzda kalma süresi gibi sartlarin disaridan müdahale ile degistirilmesi ile önlenmeye çalisilmaktadir. Bu durum da insan kaynakli hatalari ve dolayisiyla maddi kayiplari arttirmaktadir. Dolayisiyla bahsedilen problemlerin disaridan müdahale gerekmeden nihai ürünün kullanim alanina göre sahip olmasi istenen özelliklere sahip, kolay islenebilir pirinç alasim kompozisyonlari ile çözülmesi amaciyla yeni pirinç kompozisyonlari gelistirilmektedir. During the production of brass alloy products by low pressure casting method, the alloy undesirable effects occurring in the properties of the end product or in the post-production The problems created by the changes, without examining the causes in detail, casting pressure, casting acceleration, the residence time of the melt in the mold, the residence time of the mold in the cooling pool. It is tried to be prevented by changing the conditions with external intervention. In this situation It increases human-induced errors and therefore material losses. hence the mentioned problems can be found according to the usage area of the final product without the need for external intervention. Solving it with easily machinable brass alloy compositions with desired properties. For this purpose, new rice compositions are being developed.
Gelistirilen kompozisyonlar, pirinç alasimindan mamül nihai ürünün kullanim alanina ve tercih edilen üretim yöntemine göre islenen pirinç eriyigine ve nihai ürüne farkli mekanik özellikler kazandirmak amaciyla temel bilesenlere ilave olarak eser miktarlarda kalay, alüminyum, demir, nikel, bor, manganez, kursun, silikon, arsenik gibi elementlerini tek baslarina veya kombinasyonlar halinde içermektedirler. Sihhi tesisat sistemlerinin temel elemanlarindan olan armatürlerin yüksek korozyon direncine, sertlige, iyi derecede sizdirmazlik özelligine sahip olmasi, dolayisiyla dayanikli olmasi beklenmektedir. Bu elemanlarin düsük basinçli döküm prosesi ile üretimi sirasinda yüksek basinç ve yüksek sicaklik sartlarindan dogan problemlerin ortadan kaldirilmasi, dolayisiyla üretim maliyetlerinin düsürülmesi amaciyla da pirinç alasiminin kolay islenebilir olmasi, örnegin akiskanliginin yüksek olmasi gerekmektedir. Bu sebeple bahsedilen armatürlerin üretiminde kullanilmak üzere gelistirilen pirinç kompozisyonlari bahsedilen özelliklere sahip elementleri içermektelerdir. Developed compositions depend on the usage area and preference of the final product made of brass alloy. different mechanical properties to the rice melt processed and the final product according to the production method In addition to the basic components, trace amounts of tin, aluminum, elements such as iron, nickel, boron, manganese, lead, silicon, arsenic, alone or contained in combinations. One of the basic elements of plumbing systems luminaires with high corrosion resistance, hardness, good sealing it is expected to be durable. Low pressure casting of these elements problems arising from high pressure and high temperature conditions during the process and production. Rice is also used in order to eliminate it, and therefore to reduce production costs. The alloy should be easily machinable, for example, its fluidity should be high. This For this reason, the brass developed to be used in the production of the mentioned fixtures. The compositions contain elements with the properties mentioned.
Pirincin çevresiyle yaptigi kimyasal ve/veya elektrokimyasal reaksiyonlar sonucunda korozyonun olusumunu ve gözenekli bir yapi olusturacak sekilde pirinçten mamül ürünün derinlerine dogru ilerlemesini engellemek, nihai ürünün dayanikliligini arttirmak amaciyla nikel kullanilmaktadir. Ancak suya karisma ve dolayisiyla insan sagligini olumsuz etkileme riski tasimasi sebebiyle nikelin kullanim miktari Dünya Saglik Örgütü tarafindan sinirlandirilmistir. As a result of the chemical and/or electrochemical reactions of rice with its environment The product made of brass will prevent the formation of corrosion and create a porous structure. in order to prevent it from moving deeper, to increase the durability of the final product. nickel is used. However, the risk of mixing with water and thus adversely affecting human health. The amount of nickel used is limited by the World Health Organization due to its transportation.
Ancak örgüt tarafindan belirlenen maksimum degerde nikel kullanimi dahi hedeflenen korozyon direncini saglamakta yetersiz kalmaktadir. Öte yandan pirinç alasiminin kaliba aktarilma basincini düsürerek kalip asiniminin ve dolayisiyla nihai ürünün üretim maliyetinin artmasini engellemek amaciyla bor kullanilmaktadir. Bor eriyik halindeki pirincin akiskanligini arttirmakta, eriyigin döküm sicakligi degismeden daha düsük basinç altinda kaliplara aktarilmasini saglamaktadir. Ancak fazla miktarda bor kullanimi alasimin islenebilirligini güçlestirmekte, nihai ürünün sertligini ve dayanikliligini azaltarak, akiskanin yüksek basinç altinda hareket ettigi durumlarda nihai üründe hasarlarin ve dolayisiyla sizdirma problemlerinin olusmasina yol açmaktadir. Dolayisiyla bahsedilen elementlerin belirli bir miktar araliginda kullanildiklarinda beklenen etkiyi gösterirken belirli bir miktarin üzerinde bir miktarda kullanildiklarinda, alasima eklenen diger bir elementin nihai ürüne kazandirdigi mekanik özelligi ortadan kaldirabilmektedir. Bahsedilen durumlar alasima ilave edilecek elementlerin seçiminin, miktarlarinin, bilesim oranlarinin oldukça önemli oldugunu ortaya koymaktadir. However, even the use of nickel at the maximum value determined by the organization It is insufficient to provide corrosion resistance. On the other hand, the mold of the brass alloy By reducing the transfer pressure, mold wear and therefore the production cost of the final product are reduced. Boron is used to prevent its increase. Boron determines the fluidity of molten rice. increases, the casting temperature of the melt is not changed into the molds under lower pressure. provides the transfer. However, the use of large amounts of boron reduces the machinability of the alloy. high pressure of the fluid, reducing the hardness and durability of the final product. In cases where it moves under it, damage to the final product and therefore leakage gives rise to problems. Therefore, certain elements of the mentioned While they show the expected effect when used in the amount range, when they are used in large amounts, another element added to the alloy is added to the final product. can remove the mechanical property. The conditions mentioned will be added to the alloy. It has been revealed that the selection of the elements, their amounts and composition ratios are very important. puts it.

Böylece alüminyum ürünün islenmesini kolaylastirmakta, eriyik halindeki pirincin kaliplara daha düsük basinç altinda doldurulmasini saglamaktadir. Nihai ürün bir armatür olup, sahip olmasi istenen özelliklerin armatüre, düsük miktarlarda bilesen kullanimi ile kazandirilmasi sayesinde sagliga zararli olmayan, maliyeti düsük bilesenler içeren ve insan kaynakli hatalari azaltan, dolayisiyla üretim maliyetlerini düsüren bulus konusu kompozisyonun kullanilmasiyla elde edilmektedir.
