Problems solved by technology

[0004] In the existing cooling type sintering furnace, the air inlet pipe and the air outlet pipe of the cooling device are connected with the furnace body, so it is necessary to set up corresponding air inlets and air outlets on the side wall of the furnace body, which destroys the integrity of the furnace body. During the sintering operation, the air inlet and outlet become the weak link of heat loss

Abstract

An improved high-temperature atmosphere multistage circulating cooling superhigh-temperature sintering furnace comprises a furnace body, a gas outlet pipe, a gas inlet pipe, a first cooling device anda second cooling device. A heat screen assembly is arranged in the furnace body. The first cooling device comprises a fan, fan blades, a first coil pipe and a forced cooling tank. The fan blades arearranged in the forced cooling tank. The output end of the fan is connected with a fan blade shaft so as to drive the fan blades to rotate. The first coil pipe is arranged at the air inlet ends of thefan blades. The second cooling device comprises a second left baffle, a second right baffle and a second coil pipe. The second coil pipe is arranged between the second left baffle and the second right baffle. In the improved high-temperature atmosphere multistage circulating cooling superhigh-temperature sintering furnace, the fan in the first cooling device is used for drawing out hot gas in thefurnace body, and through cooling of the first coil pipe and the second cooling device, first-stage cooling on the gas is achieved; and the second cooling device comprises the second left baffle, thesecond right baffle and the second coil pipe, the second coil pipe achieves second-stage cooling on the gas, and therefore the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of high-temperature vacuum equipment, in particular to an improved high-temperature atmosphere multi-stage circulation cooling ultra-high temperature sintering furnace. Background technique [0002] During the material heat treatment process of the ultra-high temperature sintering furnace, the temperature control of the uniform temperature zone includes the heating and cooling process, and the controllability and stability of the temperature play a decisive role in the heat treatment of the material. Therefore, the technical index of the uniform temperature zone is also one of the most important parameters of the ultra-high temperature sintering furnace. The material working area is located in the uniform temperature area, which is the area for heat treatment of materials. The heat comes from several forms of thermal radiation, convection and heat conduction in the thermal field. [0003] Accurate temperatu...
