伊藤忠セラテック List of Products and Services

"Serabiz" is a synthetic spherical sintered sand that demonstrates its strengths in frame-less molds due to its lack of thermal expansion. It has high particle strength and contributes to waste reduction. Its low thermal conductivity improves the flow of molten metal. With a high ratio of point contact due to spherical particles, it maintains stable voids between particles, allowing for good gas escape. 【Features】 ■ Improved dimensional accuracy and the ability to create thinner castings ■ Prevents mold cracking during pouring and reduces veining defects ■ Achieves higher strength than silica sand through repeated mixing ■ Can be reused repeatedly as line sand, more so than silica sand ■ Improves the working environment by reducing free silica *For more details, please refer to the PDF document or feel free to contact us.

"Serabiz X (CB-X)" is a mold material with low impurity content and excellent heat resistance. Because it is made from carefully selected raw materials that are fired at high temperatures, its structure consists of dense MULLITE crystals, providing excellent wear resistance, crush resistance, and thermal shock resistance. Additionally, as it is a spherical sintered artificial sand, it has good fluidity, ensuring stable layering in layer-based modeling machines (3D printers). 【Features】 ■ Stable chemical composition ■ High fire resistance and high heat resistance ■ Low bulk density and high air permeability ■ Stable particle size distribution ■ Dense mullite crystals *For more details, please refer to the PDF document or feel free to contact us.

"Serabiz" has over 20 years of experience as a line sand alternative to silica sand, with more than 30 lines of application. By combining it with sand regeneration equipment that has high crush resistance, heat resistance, and binder removal capability, it is possible to operate with an extremely low supply of new sand. The regenerated product can be reused not only as backing sand but also as core sand and skin sand, which typically require special sand, thereby reducing the hassle of using multiple types of sand as before. Additionally, by not using silica sand, a significant reduction in crystalline silica dust and an improvement in casting quality can be expected. Itochu Ceratec provides support for technical and sand cost evaluation at the time of introduction, and continues to offer support for the management of regenerated sand conditions after implementation. *For more details, please refer to the related link page or feel free to contact us.

"Sintered spinel" is a refractory material made of magnesium-aluminum spinel (MgO·Al2O3), which has a uniform and dense structure achieved through the careful wet mixing, shaping, and firing of selected raw materials. In the steel industry, it is used as the lining refractory for molten steel ladles, and in the field of lithium-ion batteries, it is used in special ceramics such as crucibles for sintering positive electrode materials and setters. "NSP-70" has a composition close to the theoretical value of spinel, while "NSP-90" has an alumina-rich composition in which some of the alumina is solid-solubilized in spinel. [Features] ■ High melting point ■ High chemical stability ■ Resistant to both alkali and acid corrosion ■ Excellent volume stability ■ Strong against thermal shock *For more details, please refer to the related link page or feel free to contact us.

"Synthetic Mullite" is a refractory material that has a uniform structure, as it is produced by finely grinding various raw materials and mixing them in a wet process. Due to the sintering of raw materials with low impurities at high temperatures close to their melting point (1,850°C) in a rotary kiln, the structure is a dense needle-like formation. Our company manufactures three types of products: Type MM, MMS, and Type SM, each with its own unique characteristics, allowing for precise differentiation based on application. [Features] ■ High melting point ■ High load softening point ■ Low thermal expansion coefficient ■ Strong rigidity ■ High resistance to corrosion from glass and slag *For more details, please refer to the related link page or feel free to contact us.
