With the development trend of the integration of the global economy, resources, and environment, industrial kiln technology and equipment level are facing great challenges, and it is imperative to save energy and reduce emissions. Therefore, the development of industrial kilns must take a sustainable development path with high technological content, good economic benefits, low resource consumption, and less environmental pollution. Therefore, more and more industrial kilns now put forward higher requirements on the thermal insulation layer of the kiln body. This is also a great challenge for refractory manufacturers. Rongsheng refractory castable material manufacturer, through years of accumulated experience in the use of industrial kiln lining refractory materials, is more careful and perfect in the configuration and design of materials for the thermal insulation layer of industrial kilns. Rongsheng has made greater breakthroughs in the production of unshaped monolithic refractory castables for industrial kilns.

Industrial Kiln Insulation Refractory Castable for Sale
The design of the thermal insulation layer of the industrial kiln slows down the loss of temperature in the kiln, reduces thermal energy consumption, and saves fuel costs. On the one hand, it ensures the safety of production, and on the other hand, it is of great help to save production costs and prolonging the operating life of kiln furnace equipment. So, how is the thermal insulation layer of industrial kilns generally designed?
In the design of the thermal insulation layer of industrial kilns, the materials generally used are ceramic fiber products, thermal insulation bricks, and thermal insulation refractory castables. These materials, according to the different working conditions of different industrial kilns, choose different materials of thermal insulation bricks and thermal insulation refractory castables for industrial kilns and configure different indicators.
Insulation refractory castable is also called lightweight refractory castable, thermal insulation refractory castable. The Industrial Kiln Insulation Refractory Castable is mainly composed of light thermal insulation aggregate, added with refractory powder, together with bonding material and admixture. A hydraulic unshaped thermal insulation material is prepared by dry mixing according to the optimum ratio. It has the characteristics of low bulk density, low thermal conductivity, and high thermal insulation performance, and can be constructed and poured on-site. Lightweight refractory castables, also known as lightweight insulating castables, are widely used in the thermal insulation layer of boilers, industrial kilns, and other equipment bodies. It is mainly used for heat preservation of kiln and to prevent the loss of heat energy.
Classification of Industrial Kiln Insulation Refractory Castables
Insulation castables are used for boiler linings and are generally used as insulation linings. The use temperature is generally under 1000 ℃. Thermal insulation refractory castables are classified into the following three categories according to the operating temperature.
- Low-temperature lightweight castable, the operating temperature is 600℃-900℃.
- Medium temperature light castable, the operating temperature is 900℃-1200℃.
- High-temperature lightweight castable, the operating temperature is >1200℃.
Lightweight castables with bulk densities of 0.8 and 1.0 are common for thermal insulation castables. Lightweight castables with a bulk density of 0.8 or 1.0 can also be used for thermal insulation refractory castables for industrial kilns. In the refractory industry, thermal insulation castables can also be divided into 3 categories according to their bulk density.
- Semi-light castable (1.0-1.8 g/cm3)
- Lightweight castable (0.4-1.0 g/cm3)
- Ultra-light castable (less than 0.4g/cm3)
Properties of thermal insulation castables for industrial kilns
The selection of the thermal insulation layer lining of the industrial kiln generally refers to the operating temperature and thermal conductivity. In the end, it is necessary to select an insulating castable with a suitable bulk density. The smaller the bulk density of the Industrial Kiln Insulation Refractory Castables, the smaller the thermal conductivity, and the better the thermal insulation performance. During the production of thermal insulation castables, high-index thermal insulation castables can also be customized according to requirements. Insulation castables of different materials are used in thermal insulation layers of boilers and high-temperature kilns at different temperatures.
