People in the industry know that the main performance of the kiln is mainly determined by the technical and economic properties of the refractory, which directly affects the investment cost, performance, thermal efficiency and energy consumption of the kiln. Alumina hollow spheres As a commonly used refractory product, it plays a very important role in the construction of kiln. As a professional manufacturer of alumina hollow ball bricks, we have accumulated many years of production experience and knowledge of refractories, and recommend several general principles for selecting fire-resistant and thermal insulation materials.
1, furnace performance and thermal characteristics. For a kiln with intermittent work, the material with low heat capacity should be selected.
2. The safe usage temperature, heat conduction system, high temperature strength and chemical stability of the material.
3, the service life.
4, investment costs and maintenance costs.
Generally speaking, heavy refractories are more focused on a certain technical performance index, such as high temperature stability, chemical stability and so on. Light resistant insulation materials pay more attention to comprehensive technical and economic indexes of investment and operation.
Alumina hollow spheres It is made of alumina hollow spheres and fused corundum powder. After homogenizing, it is sintered at high temperature. Alumina hollow sphere brick is a new type of high temperature thermal insulation refractory. It has high temperature resistance, acid and alkali resistance, good chemical stability, small specific gravity, low thermal conductivity, and a large number of closed pores. It is widely used in high-temperature, ultra high temperature thermal equipment for petrochemical industry, ceramics and national defense research. The lining of high temperature super high electric furnaces and kilns is used to reduce furnace weight, greatly improve thermal efficiency and shorten the production cycle. It is an ideal refractory material for energy saving, material saving and high efficiency. 。 Therefore, it is also suitable for kiln production, which provides a new choice for refractory materials in kiln.
