Our high alumina refractory cement is made by forming a calcined mixture of bauxite and limestone within a rotary kiln at high temperatures. The high refractoriness, quick setting and great compressive strength make this material perfect for application in ceramic and metallurgical applications. This prodcut may be produced in a wide selection of grades, please call with your requirements.
This material is calcined from a mixture of bauxite and limestone in rotary kiln at a high temperature. Its high refractoriness, quick setting properties, high bending and compressive strength make it widely used as a refractory material in the application of ceramic and metallurgical industries. It is available in various grades as per requested.
