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 its spherical particles and stable voids between particles, it allows 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 components and excellent heat resistance. Since 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 molding machines (3D printers). 【Features】 ■ Stable chemical composition ■ High refractoriness and 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.

"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-excess composition where some 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 use of raw materials with low impurities that are sintered 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 ■ High rigidity ■ Excellent resistance to corrosion from glass and slag *For more details, please refer to the related link page or feel free to contact us.

"Alumina Ball" is a refractory raw material with excellent fluidity. By adding a small amount of MgO, the abnormal growth of crystals is suppressed, resulting in a controlled uniform crystal structure of 20 to 40 μm. It is a high-purity spherical sintered alumina containing over 99.5% Al2O3, with a dense internal structure of polycrystalline corundum. 【Features】 ■ High melting point ■ High mechanical strength ■ Strong thermal shock resistance ■ High chemical stability ■ Excellent wear resistance *For more details, please refer to the related link page or feel free to contact us.

"Serabees" 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 recycling equipment that has high crush resistance, heat resistance, and binder removal capability, it enables operations that keep the supply of new sand extremely low. The recycled product can be reused not only as backing sand but also as core sand and skin sand, which typically require special sand, thus 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 recycled sand conditions after implementation. *For more details, please refer to the related link page or feel free to contact us.
