Why do continuous heat treatment furnaces use Feipufu furnace door sealing curtains

Continuous heat treatment furnace is a heat treatment furnace that uses mechanical pushing or mechanized bottom feeding, mainly used for batch continuous heat treatment and heating of workpieces. The English name for a heat treatment furnace is a more accurate definition: an electric furnace or fuel furnace used for heating and treating furnace materials.

The heat treatment furnace requires strict control of furnace temperature and atmosphere inside the furnace. Most heat treatment furnaces use gas fuel for heating, and in order to accurately control the furnace temperature, some heat treatment furnaces use electric heating.

The continuous heat treatment furnace, whether used for nitriding, cyaniding, roasting, forging tempering, annealing, normalizing, etc., has an open door and two open ends due to the operating characteristics of its workpieces. In this case, firstly, the temperature inside the furnace is very difficult to control because it is affected by the airflow outside the furnace, which takes away a large amount of heat; Secondly, the atmosphere inside the furnace is difficult to control, as oxygen continuously enters the furnace, making it easy for the surface of workpieces, especially metal workpieces, to produce oxide scales; Thirdly, it is very difficult to close the furnace door and have the workpiece continuously enter and exit the heat treatment furnace.

Taking into account the above points, the Feipufu furnace door sealing curtain (also known as the furnace door fireproof curtain) has come out to complete this task.

The Feipufu furnace door sealing curtain has been in this world for many years. The main method is to use different combinations of refractory fibers, refractory fiber fabrics, refractory fiber belts, etc. to achieve the effect of working closely with continuous heat treatment furnaces. Due to different combinations, the Feipufu furnace door sealing curtain has relatively thin ones -5mm, relatively thick ones -50mm, single directional curtains, dual directional curtains, fiber and belt combinations, belts formed separately, pull ring suspension, clamp clamping, etc. It is always a customized product based on the characteristics of continuous heat treatment furnaces.

The use of Feipufu furnace door sealing curtains (furnace door fire curtains) has three main functions: firstly, energy saving and consumption reduction; secondly, improving product quality and excellent rate; and thirdly, optimizing the working environment for personnel.
