Shinagawa Refractories Australasia (Shinagawa) has established an enviable reputation for the manufacture and supply of quality refractory and insulating materials to the Australasian, South East Asian and Pacific Rim markets.
The Aluminium and Alumina Industry

Shinagawa Refractories Australasia has long been a dominant supplier to aluminium smelters and alumina calciners. High purity SHIRAL fireclay and insulating brick are the industry standard in anode baking furnaces. In reduction cells SHIRAL fireclay brick and our insulating boards are the products of choice. For melting and holding furnaces, Shinagawa manufactures a wide range of aluminium resistant products such as SHIRAL nonwetting brick, SHIRACRETE monolithics and a host of back up insulating castables and boards. SHIRACRETE, SHIRAGUN and SHIRAPLAS products are proven in alumina calciners where campaign lives have been extended considerably.

SHIRAL - Alumina Refractory Bricks

Shinagawa offers a complete range of high quality dry pressed alumina bricks, ranging from 35% to 95% in alumina content. These materials are manufactured with state of the art equipment, including computer controlled hydraulic presses that tightly regulate brick sizing and compaction pressure.

Firing is accomplished in multi-stage kilns to ensure even and accurate burning and consistent properties. Strict quality control standards control brick appearance and inherent variables such as strength, density and porosity. This quality approach serves three product groups in the SHIRAL dry pressed brick line:

· Fired High Alumina Bricks – these are produced from premium grades of alumina’s and bauxite’s and include brick with very low porosity, high strength, high thermal shock resistance and metal slag resistance. Some special grades are manufactured with phosphate bonds or andalusite aggregate for specific applications.

· Chemically bonded High Alumina Bricks – these high alumina, phosphate bonded brick are ideally suited to steel ladle or molten aluminium furnace applications due to their unique chemistry, including special aggregates and additives.

· Superduty and Fireclay Bricks – these lower alumina grades of brick are produced to the same exacting standards as the high alumina grades. These brick exhibit good strength and spall resistance over a range of service conditions and find use in a variety of applications.
