Large industrial high temperature furnace energy saving coatings into the main program
Large-scale industrial furnace is fired for calcining materials or products, refractory brick device called a large-scale industrial furnace . Many types of large industrial furnaces can be divided into general industrial large-scale industrial furnaces , rotary large industrial furnace, coking large industrial furnaces , induction furnaces and other large industrial . But generally large industrial furnaces must reach an internal temperature above 350 ℃ , heat a large industrial furnace temperature can reach 2000 ℃. Generally large industrial furnaces heated mostly by electricity, coal , oil, gas or electromagnetic induction heating temperature, heat transfer large industrial furnaces in three ways , namely heat conduction , convection and radiation heat transfer . In the low-temperature phase , convective heat exchange with heat -based, while the high temperature phase (800 ℃ above ) , then the radiation heat transfer based, as the temperature rises , radiation heat transfer plays a growing role the stronger the radiation heat .

Due to the special properties of large industrial furnaces and heat , which requires large-scale industrial furnace construction and insulation do well. With the advances in the world of industry, large-scale industrial furnace is also moving large-scale, efficient and longevity development, large-scale industrial furnace gradually optimized structure , improve the rate of improvement of energy efficiency , the unit energy consumption decreased productivity , and large industrial furnaces increase the useful life of the material , which features high-temperature coatings for demanding higher performance , located in Fengtai District Dongtieying Weihua Sheng Chi 's many diverse species kiln temperature functional coatings , functional outstanding, for high-temperature furnace significant energy saving , energy saving, production to bring considerable economic benefits.

Currently in the field of industrial heating large industrial furnace energy saving methods and techniques used are: lightweight lining materials , and its typical representative is the " all- fiber furnace " ; Regenerative industrial furnaces , heat flow downstream in the waste heat recovery to proceed ; IR coating technology , the fundamental weakness of the coating aging , decay emissivity ; addition, in order to increase the projection area of the furnace ; distributed control method using a computer to improve the control precision , but the thermal efficiency of the furnace and can not play a fundamental effect. Our pursuit is : how these existing energy-efficient technologies alone or integrated use, but also further substantial energy savings. It is required that the resource situation and technological development. Now more famous domestic production of high temperature industrial furnace energy saving features large paint manufacturers , Beijing Hua Wei Sheng Zhi Chemical Co., Ltd. is specialized in producing high-temperature furnace manufacturers of energy-saving coatings , high temperature furnace lining large industrial energy saving protective coatings of high production technology , paint temperature can reach 1800 ℃, acid and alkali , high hardness , impact resistance and other characteristics. People through the heat balance calculations or tests found resistance furnace furnace regenerator and heat loss by up to 60 % to 70 %, while the effective thermal heating of the workpiece is only 25 % to 30 %. The fuel furnaces are basically similar . On this basis, so the use of a smaller heat capacity and thermal insulation materials Zhulu lightweight materials to reduce the heat storage and heat loss . This energy-saving methods , but the heat "blocking" in the furnace , the heat rays did not change the " diffuse " state , does not solve the problem of thermal radiation is in place , so the effective thermal heating of the workpiece is still low .

The following high-temperature functional coatings can solve large-scale industrial furnace energy-saving rate is less than the current problems, such as local thermal insulation is poor, diffuse severe in large industrial furnaces , industrial kilns regenerative too large , large-scale industrial furnace lining High temperature oxidation corrosion serious , large-scale industrial furnace local structural closure not a serious problem , such as energy consumption .
