TR DESCRIPTION ANORTHITE CRYSTAL PHASE GLAZE COMPOSITION DEVELOPED BY USING ALUMINA-BASED FIRE ZONE WASTE ROLLERS WITHOUT CRISTOBALITE PHASE INSTEAD OF ALUMINUM OXIDE Technical Field The invention was developed using alumina-based fire zone waste rolls without cristobalite phase instead of aluminum oxide. Orthite is related to crystal phase glaze composition. In particular, the invention is designed to be deformed and separated into waste; It is about the anorthite crystal phase glaze composition developed by using fire zone kiln rolls, which do not contain a cristobalite phase in their mineralogical structure, instead of Alzoa and SiO2 in the glaze composition of porcelain floor tiles fired at 1185-1210 0C. Background of the Invention: In the ceramic coating materials industry, roller kilns are used in the sintering process of tile production. When the mineralogical and chemical analyzes of roller kiln rolls are examined, it is known that they contain elemental oxides present in the ceramic microstructure. During the firing process, ceramic kiln rollers rotate under the influence of high temperature and the weight of the tiles, allowing the tile to move forward in the kiln. Rolls imported from abroad break, crack or lose their shape over time, so they cannot be used in ovens again. Unusable rolls are thrown away and cause the amount of waste to increase. The amount of furnace rolls thrown away varies depending on factors such as the usage period of the furnaces, tile sizes, and furnace maintenance, and it has been calculated that approximately 50,000 kg/year of furnace roll waste is generated on average. When the chemical analysis of the rolls supplied from different companies is examined, it is seen that they contain high amounts of AI203 and SiOz. The ratios of alumina and silica in the composition of siren and frit are very important. Alumina can react with silica or basic oxides due to its both acidic and basic properties. Since the melting temperature alone is 2050"0, the glaze structure has the ability to increase the melting temperature. It increases temperature resistance, strength, viscosity, hardness and resistance to acids and bases, provides opacity in the glaze and reduces the coefficient of thermal expansion. In addition, it provides whiteness in glaze recipes. In the chemical analysis of kiln rolls, 14-25% SiO2 indicates that it can be used instead of quartz. Silica is the basic raw material of glass composition used in all glazes and frits. With the influence of melters, the silica in glaze and frit has the ability to glaze. Increasing the amount increases the melting temperature, reduces the fluidity, decreases the coefficient of thermal expansion, and increases hardness and strength. Opaque frit, clay, and feldspar are used as silica sources in the production of frit and glaze. It is used to provide aesthetics and aesthetic appearance. Dullness occurs on the surface as the light does not reflect properly from the surface and the reflections are scattered. Internal interfaces formed in the glaze due to surface smoothness, phase separation or crystals and the refractive index of the glaze create opacity. Matt frit is used in the glaze recipe to provide matte properties. Frit forms are used to melt the glaze at low temperatures, to form the desired phases and to increase the resistance of the tile surfaces to chemicals. Since clay and kaolin are essential ceramic raw materials, they are used to facilitate the shaping of the structure and to maintain the strength of the formed structure. When quartz comes together with basic oxides in its glaze structure, it acts as a glass maker. Zircon is also used to add opacity. Dolomite mineral is used as a magnesium source to improve the chemical resistance and hardness of the glaze surface. Albite is an alkali feldspar and is used for melting wax and forming the glassy phase structure. When used in appropriate amounts in alumina glazes, it improves its resistance to acids and bases with its cracking effect. In the current technique, furnace rolls that are permanently deformed and unusable and contain a high chemical content of AlzOa cannot be evaluated and are separated as waste. In the literature, in the European patent application numbered EP307152281, it is stated that the aluminum oxide matrix is 55 - 90% by volume and zirconium dioxide is 10 - 45% by volume in the material produced by mixing oxide Ce02, lanthanum oxide La203 and praseodymium oxide Pr6011 followed by sintering, and after sintering, It relates to a ceramic material in which the produced material contains at least 75% of the tetragonal modification of zirconium dioxide and is chemically stabilized by a mixture of yttrium oxide and cerium oxide. The improved properties are achieved by the fact that the aluminum oxide matrix in the form of hexagonal plates of LaAl11018 composition is 10 - 75% and the ratio of the added preseodymium oxide in the total mixture is 0.1 - 1.0% by volume, and the material produced during sintering is a mixture with aluminum oxide, lanthanum aluminate and/or zirconium oxide. "It is achieved by the formation of crystal." In the mentioned patent application, a ceramic material composition containing alumina is disclosed. In the literature, in the patent application numbered TR 2018 19404 in the records of the Turkish Patent Institute, it is stated that "The invention refers to underglaze engobes used in the ceramic glazed tile manufacturing industry. It is related to their preparation and production methods. The invention is particularly related to the use of kiln rolls, which are recycled materials, in order to reduce costs and contribute to the environment in the preparation of underglaze engops used in the ceramic glazed tile manufacturing sector. In the mentioned application, roll waste is used instead of zircon (ZrSIO4) raw material in the engop recipe. Again, in the literature, in the Turkish Patent Institute records, in the PCT application numbered WO 1999/0050, it is stated that "The present invention is related to the field of production of lanthanum chromite based electro-conductive ceramics and targets applications at high temperatures (approximately 1727"0). Its purpose is to increase the heating rate, which will make it possible to reduce the operating time, and to provide improved thermal stability, which will increase the operational reliability at high temperatures. This aim is achieved by supporting lanthanum chromite-based ceramics containing magnesium chromite, yttrium chromite, zirconium dioxide, cerium dioxide with lanthanum aluminate. " statements are included. In the mentioned application, electro-conductive ceramic material is disclosed. For the reasons mentioned above, a new automatic anorthite crystal phase glaze composition was needed. Disclosure of the Invention Based on this state of the art, the aim of the invention is to introduce a new anorthite crystal phase glaze composition that eliminates the existing disadvantages. Another aim of the invention is to present a structure that contributes to the formation of the phase that will provide the desired feature in the microstructure by providing whiteness and mattness properties. Another aim of the invention is to introduce a structure that reduces the need for raw materials in the recipe by enabling the recycling of inert oven rolls. Another aim of the invention is to create a structure that increases the abrasion resistance of the glaze by using the hard corundum and mullite phases found in the kiln rolls sintered at high temperatures in the glaze composition. Another aim of the invention is to create a structure that helps protect the environment by recycling waste materials. Another aim of the invention is to present a structure that allows use even in the most sensitively produced semi-finished product located on the top layer. Detailed Explanation of the Invention In this detailed explanation, the innovation that is the subject of the invention is explained only with examples that will not create any limiting effect on a better understanding of the subject. Porcelain floor tiles containing grams of zircon in their glaze composition are deformed and separated into waste; It is characterized by the fact that it contains 4-15 grams of kiln roll waste containing anorthite crystal phase glaze composition developed by using fire zone kiln rolls, which do not contain a cristobalite phase in their mineralogical structure, instead of Al203 and SiO2. The anorthite crystal phase glaze composition that is the subject of the invention consists of 9-15 grams of opaque frit, 18-28 grams. At the same time, invention is deformed and separated into waste; It is a production method of anorthite crystal phase glaze composition obtained by using fire zone kiln rolls, which do not contain a cristobalite phase in their mineralogical structure, instead of Al203 and SIO2. The chemical and mineralogical analysis of the mentioned waste furnace rolls is carried out and the furnace rolls, which are found to not contain cristobalite and contain mullite and corundum phases, are separated to be used in the recipe. preparation, weighing the raw materials in the recipe at the specified rate and loading the alumina ball mill so that the total amount is 2000 kg, adding 50-55% water to the mill and grinding in the mill for 7-8 hours, arranging the density measurement result with a pycnometer to be 1550 g/It, 42, It is characterized by the method of sintering the tile on the engop floor tile body measuring 5cmx42.50m in the 90-degree oven regime. Opaque frit. In covering the dark natural color of the body; It is used to provide row covering properties and aesthetic appearance. Dullness occurs on the surface as the light does not reflect properly from the surface and the reflections are scattered. Internal interfaces formed in the glaze due to surface smoothness, phase separation or crystals and the refractive index of the glaze create opacity. Matt frit is used in the glaze recipe to provide matte properties. Frit forms are used to melt the glaze at low temperatures, to form the desired phases, and to ensure that the square surfaces are highly resistant to chemicals. Since clay and kaolin are essential ceramic raw materials, they are used to facilitate the shaping of the structure and to maintain the strength of the formed structure. When quartz comes together with basic oxides in its glaze structure, it acts as a glass maker. Zircon is also used to add opacity. Dolomite mineral is used as a magnesium source to improve the chemical resistance and hardness of the glaze surface. Albite is one of the alkali feldspars and is used for melting glaze and forming the glassy phase structure. When used in appropriate amounts in alumina glazes, it improves its resistance to acids and bases with its cracking effect. The invention enables the use of kiln rolls as alumina source instead of alumina raw material within the glaze structure. Firstly, chemical and mineralogical analysis of the oven rolls is performed. Furnace rolls that do not contain cristobalite and whose mullite and corundum phases are detected are separated for use in the recipe. Furnace rolls with appropriate mineralogical and chemical structure, which are allocated to waste, are crushed in the crusher and ground in the mill. Based on the standard recipe, the oxides are worked in close proportions by weight and prepared according to the Seger method. The raw materials in the recipe are weighed at the determined rate and loaded into the alumina ball mill, with a total amount of 2000 kg. 50-55% water is added to the mill and the grinding process is carried out in the mill for 7-8 hours. The density measurement result with a pycnometer is adjusted to be 1550 g/lt. In this regime, the tile is sintered. should be below. The rolls contain mullite and corundum phases. It does not contain a cristobalite phase. 1/3 of the mill should be filled with raw material + water and 1/3% with alumina ball, and the grinding process should be carried out for 7-8 hours. The density of the recipe should be between 1450-1600 g/It. must be sintered. Material characterization is important first during the application of the invention. Rolls that are not suitable for mineralogical analysis cannot be used in the recipe. Otherwise, it will cause unwanted errors and losses in production. In terms of chemical content, oxide rates should be similar and close to the content of the raw material that will replace it in the current situation. In order to ensure the desired standard values in the final product, the weight ratios in the recipe should be close to each other and the resulting phases should be the same. The recipe should be calculated as a percentage and the raw materials should be adjusted and weighed according to 1 ton, 2 ton and 5 ton mills. The weighed raw materials should be poured into the alumina ball mill and attention should be paid to the amount of water to be added and the amount of balls. Attention should be paid to the mill grinding time. Glazing grammage should be adjusted according to the product size. Firing temperature is important in shaping the final product. TR
