Lift furnace insulation, the choice is still pretty much.
For example, castable masonry furnace, refractoriness is obviously better than other materials, and the chemical performance is stable, wear resistance, anti-erosion, anti-air erosion, long service life. Of course, short board also has, pouring furnace cycle is longer, manpower and material resources are larger, and need to be put into use after the oven. It should be noted that the castable furnace body is not suitable for the furnace which often stops the furnace, because the castable is not resistant to rapid cooling and rapid heat, frequent opening and stopping of the furnace will lead to the cracking of the castable lining, affecting the insulation effect and even the furnace outside the channel, causing greater loss.
Firebrick furnace is also widely used, good fire resistance, both wear resistance and chemical stability, not easy to be eroded, and long service life. But the thermal conductivity is too high, the insulation is slightly poor, the density is a heavy refractory, the furnace body steel frame bearing requirements are high, like other heavy refractory, not resistant to hot and cold, maintenance is a little trouble, the need to stop the large area of masonry.
The whole fiber furnace lining is a popular thermal insulation scheme in recent years. It is composed of ceramic fiber module and ceramic fiber blanket. The thermal conductivity of ceramic fiber is lower than that of firebrick. More than 75% lighter than light firebrick.
The benefit from this is that the adiabatic effect is better than other lining, so as to lock the heat as much as possible, reduce fuel consumption, and effectively save cost for enterprises.
In addition, installation is easier, workers can be installed on site after the guidance of technicians, saving construction costs.
The installation can be put into use, shorten the construction period; As each module is fixed by a separate anchor nail, it is convenient for maintenance, so the modules that need to be replaced can be replaced.
Ceramic fiber module is lightweight insulation material, which greatly alleviates the load bearing pressure of kiln frame, and the kiln body has a longer service life. There are 5 temperature levels to choose from. Economical and reasonable solution can be chosen according to kiln conditions.
Of course, there are also certain defects. For example, the structure of ceramic fiber products determines its poor wind erosion resistance. Although a hard shell can be formed on the surface with curing agent, it is still not applicable in the furnace environment with high wind speed.
