産業上の利用分
本発明は、洋瓦のような平板状の屋根瓦の製造
方法に関する。DETAILED DESCRIPTION OF THE INVENTION Industrial Application The present invention relates to a method for manufacturing flat roof tiles such as Western roof tiles.
従来の技術及び発明が解決しようとする問題点
一般にタイル等の平板状の陶磁製品は乾式プレ
スによつて素地を形成した後、施釉して焼成され
ているが、焼成時の収縮により割れや歪みを生ず
るため300mm角程度のものが限度でそれ以上の大
きさのものは歩留まりが悪く製造が困難であつて
400mm角以上の大きさを必要とする平板瓦では高
価になる欠点があつた。Problems to be Solved by the Prior Art and the Invention In general, flat ceramic products such as tiles are formed into a base by dry pressing, then glazed and fired, but shrinkage during firing causes cracks and distortions. Because of this, the limit is around 300mm square, and larger sizes have poor yields and are difficult to manufacture.
Flat tiles that require a size of 400 mm square or more have the disadvantage of being expensive.

た。Means for Solving the Problems The present invention, as a means for solving such problems, uses 50 to 70% by weight of siyamoto and 10 to 70% by weight of clays.
A powder mixture of 30% by weight and 10 to 30% by weight of slag was dry press-molded, then glazed and fired.

製造し得る効果がある。Functions and Effects of the Invention The present invention has the above-mentioned structure, and since the main ingredients are slag and slag that contain almost no moisture, the shrinkage during firing is extremely small, and it is difficult to cause cracks or distortions, so it can be used in large-sized products of about 500 mm square. In addition, the slag acts as a sintering aid, making it possible to produce high-strength and thin products.

る。 In the present invention, the content of syamoto is set at 50 to 70% by weight because if it is less than this range, shrinkage during firing becomes large and cracks and distortions are likely to occur.On the other hand, if it is too much, it becomes porous and has high water absorption. This is because clay is not suitable as a roof tile, and the reason why clay is set at 10 to 30% by weight is that if it is less than this range, the bonding force will be weak and forming will be difficult, whereas if it is too much, it will be difficult to release from the press mold. Moreover, the reason why the slag content is set at 10 to 30% by weight is that if it is less than this range, the sintering force will be small and the strength will be insufficient, whereas if it is too much, the hardness will be too high and the workability will be poor. This is because it decreases.

れた性質を有し、かつ、焼成による収縮が0.65％

高い歩留まりが得られた。Example: 60% by weight of Siyamoto, 20% by weight of Mizunami Kibushi clay,
20% by weight of crushed slag was mixed and formed into a base with a length of 460 mm, width of 303 mm, and thickness of 13 mm using a dry press. After glazing and firing at 1300℃, the bending strength was determined.
347.6Kg, water absorption rate of 4.9%, extremely excellent properties as a roof tile, and shrinkage due to firing is 0.65%
Because it was extremely small, there was no quenching cracking or distortion, and a significantly high yield was obtained.
