What is the difference between mesh belt furnace muffle furnace?

Mesh belt furnace can be divided into muffle free mesh belt furnace muffle mesh belt furnace. They are used to heat quench the protective atmosphere of small medium-sized parts, are ideal furnace types for continuous thin-layer carbonitriding ( carburizing) operation. The type of furnace used mainly depends on the technical requirements process characteristics of the parts processed. Each mesh belt furnace has its advantages disadvantages

(1) As in the muffle mesh belt furnace the non muffle mesh belt furnace, the workpiece moves smoothly on the mesh belt, there is no relative movement between them. Therefore, the quenching deformation of parts can be reduced.

(2) The furnace space with muffle mesh belt furnace is much smaller than that without muffle mesh belt furnace, so the gas consumption is much smaller.

(3) Similar to the vibrating hearth furnace, the furnace temperature gas uniformity of muffle furnace are obtained by the directional natural flow of gas itself. The muffle mesh belt furnace is equipped with a circulating fan, which makes the furnace gas produce axial convection achieves uniform furnace temperature gas, so it is better than muffle mesh belt furnace.

(4) the point of view of maintenance of heating elements, radiant tube heating is mainly used in muffle free belt furnace, its maintenance replacement are relatively convenient. After many times of optimization design improvement of resistance wire of heating element of muffle furnace, its maintenance replacement are also very convenient.

the point of view of the moving state of the mesh belt, the mesh belt without muffle furnace moves reciprocally in the upper lower parts of the furnace chamber. The alternating effect of heating cooling is small, the service life of mesh belt is long. The mesh belt circulates inside the furnace through the outside of the furnace (also through the cooling water tank), so its cold hot alternating stress is large, thus reducing the service life of the mesh belt.

(6) The removal maintenance of muffle mesh belt furnace is much simpler than that of non muffle mesh belt furnace.

(7) It is much easier to adjust control the atmosphere in the mesh belt furnace with muffle than without muffle.

The choice of muffle furnace depends on your actual use conditions.
