Lightweight Refractory Aggregate

Lightweight refractory aggregate is raw material of refractory castables. It is the important composition of monolithic refractory materials. It usually takes the form of particles with various granularity according to various construction demand. For instance, some construction may demand the larger granularity while some construction may prefer tiny granularity.

Lightweight refractory aggregate can be used as the thermal insulating materials which can prevent the energy and thermal loss. It is widely used in metallurgy industry, petroleum industry, chemical industry, steel making industry and some other industries.

Description of Lightweight Refractory Aggregate

Lightweight refractory aggregates are refractory material which can be made into refractory castable with some other refractory material such as binding agent and additives. With the development of industry, there are more and more demand for the refractory construction materials. In specifically, all kinds of furnaces, kilns, stoves and other heat treatment equipments are indispensable for the general operations in industry. As we all know, those heat treatment equipments of industries are applied to a series of high temperature process. Therefore, the refractory materials are necessary in the building and fixing of heat treatment.
