Among our wide portfolio of unshaped refractories, AMTC is engaged in offering an extensive range of Dense Castables that are widely used in various industries. AMTC is able to supply a full line of Traditional Castable Refractories utilizing various bonding systems.

AMTC Dense Refractory Castables can either be cast or pumped in place ideal for constructing ovens and for hot Face Lining in kilns and furnaces for needs within the iron and steel, glass, petrochemicals, non-ferrous, furnaces, kilns, and fertilizers industries.

AMTC supplies different traditional Alumina-Silicate Castables with a wide range of Al₂O₃ content ranging from 40 up to 95%, and bulk density of 2.00 and 2.7 gm/cm³ respectively. They are produced by blending well distributed Calcined Kaolin, Bauxite and/or Alumina mixture with Calcium Aluminate Cement (CAC) as a hydraulic bond.

Our Dense Castables are ideal for cold repairing of Face Linings of industrial furnaces with working temperatures ranging between 1400 ^oC and up to 1750^oC depending on their Al₂O₃ content.

Fireclay (40-45% Al₂O₃) and Aluminous Fireclay (50-65% Al₂O₃) are recommended for application at 1400-1580^oC service temperatures. On the other hand, a service temperature of 1600-1750^oC is suitable for application of High Alumina Castables with Al₂O₃ content of 70-95%.

Designed as per international standards, our range can also be customized as per the specific requirements of our clients. We bring to our clients a qualitative range of Dense Alumina Castables that are Conventional Castables catering to the application needs of various industries such as steel, cement, petrochemical and non-ferrous industries. Known for its strength and low maintenance, our range is available in customized specifications to the clients.
