Si3N4 Bonded SiC Blast Furnace Bricks
Si3N4 Bonded SiC Bricks are produced using high quality silicon carbide and industial silicon powder as starting materials, firing at high temperature by nitridation reaction. Characterized by good thermal shock resistance, good alkali corrosion resistance, good slag resistance, high strength and high thermal conductivity, the bricks are mainly used in severe parts of iron-making blast furnace, such as the lower part of stack, belly, bosh and tuyere. The bricks were awarded the "The 2nd prize of National Science & Technology Progress" by the former Metallurgy Ministry in 1987. The bricks have been used successfully in about 10 large steel companies such as Baosteel and Wuhan Iron and Steel Corporation in China, and also have been exported to some countries and regions such as Russia, etc.
SiAlON Bonded SiC Corundum Bricks
SiAlON bonded SiC bricks are produced using high quality silicon carbide, industrial silicon powder and aluminum powder as starting materials. Firing at about 1500°C by nitridation solid solution reaction. Compared with Si3N4 bonded oxidation resistance, the bricks are mainly used in the lower part of stack, belly and bosh of BF. The bricks were swarded the "The Third Prize of National Science & Technology Progress" in 1998 and have been used successfully in Blast Furnace of Anshan.

Customized Heterotypic Technical Ceramics
AIZA is a Lianyungang based Sino-Foreign joint venture corporation. It is a Chinese producer of calcined alumina and a manufacturer of alumina ceramics, such as alumina ceramic ball, alumina ceramic cylinder, alumina wear tile, ceramic insulator, ceramic element, ceramic beads, and other insulation ceramics with self-prepared material as well as German and Japanese material.
Since its creation, AIZA has served most of Chinese customers, Nanjing Huade, Zhuzhou Xianghuoju, and Chaozhou Sanhuan, which are eminent manufacturer of spark plug and advanced ceramic in China. Its "TCH" brand calcined alumina is well accepted by our customers.
In 2008, AIZA purchased 70 key equipment from Shanghai Morgan Matroc after its closure in China. The equipment includes isostatic press machine, dry press machine, hot press cast machine, ball mill, alumina spray prilling tower (centrifugal and pressure), polishing machine, etc. The equipment has been successfully installed in our factory by the end of 2008. Now, AIZA have succeeded in establishing itself as sole Chinese manufacturer of ceramic nozzle by isostatic dry bag pressing process. Besides, the most experienced technical engineer of former Shanghai Morgan Matroc also joined us, which is the precious source of our confidence of ensuring products quality.
TQC Procedures and ISO 9001: 2000- Certification
Our experienced QC will supervise the production and check the quality before delivery. We conduct TQC procedures according to ISO 9001: 2000-certified guidelines. In order to ensure better quality, we carry out five processes below:
