The difference between a muffle mesh belt furnace and a muffle mesh belt furnace
From the point of view of gas consumption, the furnace space of the muffle mesh belt furnace is much smaller than that of the muffle mesh belt furnace, so its air consumption is also much smaller.
From the point of view of the maintenance of the heating element, the muffleless mesh belt furnace mostly uses radiant tube heating, and its maintenance and replacement are more convenient. The heating element resistance wire of the muffle mesh belt furnace has been optimized and improved many times, and its maintenance and replacement are also very convenient. Both have their own advantages.
From the point of view of the movement state of the mesh belt, the mesh belt furnace with muffle is the same as the mesh belt furnace without muffle. The workpiece moves forward steadily on the mesh belt without relative movement between each other, so the quenching deformation of the parts can be reduced. effect. The mesh belt of the muffleless furnace moves back and forth between the upper and lower parts of the furnace. The mesh belt is less exposed to the alternating stress of cold and heat and has a long service life. The mesh belt with a muffle furnace is circulated from the inside of the furnace through the outside of the furnace (and through a cooling water tank), so the alternating stress of cold and heat is very large, and the service life of the mesh belt is reduced.
The furnace temperature and furnace gas uniformity of the Muffle mesh belt furnace are obtained by the directional natural flow of the gas itself. The muffle-free mesh belt furnace is equipped with a circulating fan to make the furnace gas produce axial convection to achieve the furnace temperature and uniformity of the furnace gas, so it is superior to the muffle mesh belt furnace.
Whether it has a muffle mesh belt furnace or a muffle mesh belt furnace, it is an ideal furnace type for heating and quenching of medium and small parts in a protective atmosphere or for continuous operation of thin carbonitriding (or carburizing). The type of furnace is mainly based on the technical requirements and process characteristics of the processed parts.
