Abstract

The invention discloses a high-temperature tunnel furnace for sintering and molding powder materials. By adopting the tunnel furnace, the invention can well improve the sintering reliability of powder materials, improve the service life of the sintering furnace, and realize automation The loading and unloading of the material; the present invention sets four sintering furnace units, and the corresponding setting of its temperature, sintering at a lower temperature at the beginning, and then use a higher sintering temperature after reaching a certain density Sintering can ensure the density of sintering and sintering performance. Before discharging, the temperature is further lowered and sintered gradually to prevent the adverse effects of temperature changes on the crystal grains; The powder material is slightly oscillated to ensure the compactness and refinement of the grain of the powder material after sintering, and to improve the molding reliability of the powder material.

Description

technical field

[0001] The invention relates to the technical field of powder material molding equipment, in particular to a high-temperature tunnel furnace used for powder material sintering and molding. Background technique

[0002] For the molding of powder materials, the powder is generally made into compacts by pressing or other methods. However, for powders, this pressed compact cannot meet the requirements of its use, especially mechanical performance and physical properties. Therefore, it is generally necessary to carry out sintering treatment so that the particles of the powder can be well combined to ensure various mechanical performance requirements such as strength.

[0003] The current sintering equipment is generally realized by a sintering furnace, but for the sintering furnace, a single furnace body is generally used for sintering. During the sintering process, it is controlled according to different temperature requirements. Is this method inconvenient? Th...
