Importance of Ceramic Fiber Modules to Heating Furnaces

Anchor-Tech ceramic fiber modules are low thermal conductivity, lightweight and energy-saving refractory materials that are widely used in many heat treatment furnaces. At present, the use of ceramic fiber modules has become institutionalized and normalized. It is a material that must be used in kiln overhaul. So what is the importance of ceramic fiber modules to heating furnaces?

01. Reduce the surface temperature of the furnace

Under normal heating production conditions, the heating furnace insulation and heat insulation were tested. The test parts were heating, equalizing and furnace top. The test results showed that the average surface temperature of the furnace wall without ceramic fiber modules was 271.0℃, while the average surface temperature after the ceramic fiber modules were applied was 119.3℃. The surface temperature of each part of the furnace body decreased. It can be seen that the ceramic fiber module is very effective for the insulation of the furnace wall!

02. Reduce fuel consumption and increase production

The installation of the product lining was carried out at the same time as the heating furnace was overhauled. A comparison of the same period showed that the application of Anchor-Tech ceramic fiber modules as the furnace lining reduced the energy consumption of the heating furnace and increased the output of the heating furnace. The cumulative gas consumption decreased by 4.7%, while the amount of billets entering the furnace increased by 6.09% and the output of finished products increased by 6.72%.

03. Reduce oxidation and burning rate

The use of Anchor-Tech ceramic fiber modules as lining improves the quality of steel burning . The thermal sensitivity of the furnace is increased, the heating speed is fast, and the oxidation and burning rate of the steel billet is controlled at 1.55%-1.65%, which is 0.157% lower than that of the heating furnace without ceramic fiber modules .

04. Extend the life of the furnace

After using Anchor-Tech ceramic fiber modules as furnace lining, the side wall temperature dropped by an average of 41°C and the furnace top temperature dropped by an average of 113.9°C, delaying the rapid cooling and heating caused by direct flame erosion, thereby extending the service life of the furnace.
