Generally, industrial kilns built with refractory materials usually have low energy utilization rates. Thermal conductivity is an essential and important data for the design of high-temperature thermal equipment. Increasing the use of thermal insulation materials for masonry kilns can reduce the heat loss of walls, improve thermal efficiency, increase the output of thermal equipment, reduce energy consumption, and work more cost-effectively.

[/vc_column_text][vc_column_text]In any medium, when there is a temperature difference between the two places, heat transfer will occur, and heat energy will be transferred from a higher temperature to a lower temperature. In order to maintain an indoor temperature suitable for people to live and work all year round, the materials used in the outer structure of the house must have certain thermal insulation properties. Building materials have a certain thermal insulation effect. The thermal insulation performance of a material is determined by the thermal conductivity of the material. The smaller the thermal conductivity, the better the thermal insulation performance. Usually what we call thermal insulation materials are materials with a thermal conductivity (λ) of less than 0.2326W/(MK). This material is characterized by small voids, light bulk and weight, and good thermal insulation effect. Since thermal insulation materials are often porous, there is air in the pores of the material, which plays a role in radiation and convection. Therefore, strictly speaking, when heat passes through the material layer, it does not rely on thermal conductivity alone, but because radiation and convection account for a small proportion, they are not considered in the thermal calculations of buildings.[/vc_column_text][vc_column_text]One stop solution for steel industry[/vc_column_text][/vc_column][/vc_row]
