Problems solved by technology

[0002] Tunnel furnace is an industrial furnace for heat processing or heat treatment during the conveying process of objects. In the tunnel furnace, the object to be processed is heated by the tunnel furnace during the process of being conveyed by the mesh belt. In this process, it is necessary to ensure its The internal temperature meets certain requirements and remains stable; at the same time, due to the small structure of the existing tunnel furnace, it can only perform thermal processing or heat treatment on small-sized objects, and is not suitable for large-sized objects

Abstract

The invention relates to a large-sized aging tunnel furnace. The large-sized aging tunnel furnace comprises a feeding section, a heating section and a cooling and discharging section which are arranged in sequence. A conveying mechanism which extends from the feeding section to the cooling and discharging section is arranged in the heating section. The heating section comprises a temperature rising section, a constant-temperature baking section and a temperature falling section which are of the same structure and are independently controlled. The temperature rising section comprises a furnacebody and a furnace cover matched with the furnace body. The furnace body comprises a first heat-insulation layer. Main heating pipes are arranged in the upper portion of conveying cavity. Fans are arranged at the bottom of the conveying cavity. Auxiliary heating pipes are arranged at air inlets on the two sides of the fans. The conveying mechanism is located between the main heating pipes and thefans. According to the large-sized aging tunnel furnace, the main heating pipes are arranged above the conveying mechanism, and the fans and the auxiliary heating pipes are arranged below the conveying mechanism so that the internal temperature of the heating section of the tunnel furnace can meet certain requirements and can be kept stable; and meanwhile, the furnace cover which can be opened towards the two sides is arranged, so that hot working or heat treatment of large-sized objects is achieved through the large-sized aging tunnel furnace.
