Microwave experimental furnace

Abstract: The invention discloses a microwave experimental furnace. The microwave experimental furnace comprises a furnace body, a hollow thermal-insulation module and a crucible, wherein the hollow thermal-insulation module is arranged inside the furnace body, and the crucible is arranged inside a cavity in the thermal-insulation module and used for containing a material. Temperature measurement holes areformed in the crucible and the thermal-insulation module, a high-temperature infrared thermometer and a low-temperature infrared thermometer are installed on the furnace body at the same time, and receive infrared rays generated by the surface of the material through the temperature measurement holes, and axes of the receiving ends of the two infrared thermometers are intersected on one point of the surface of the material. According to the microwave experimental furnace, the high-temperature infrared thermometer and the low-temperature infrared thermometer are installed on the microwave furnace body at the same time for temperature measurement, and therefore the requirement for full-temperature section continuous temperature control can be met.

Microwave curing equipment for beach surface of uranium tailing pond

Abstract: The invention discloses microwave curing equipment for a beach surface of a uranium tailing pond. The microwave curing equipment comprises a microwave heating system, a lifting device, an exhaust gastreatment system, a power supply system and a moving device, the microwave heating system moves to the beach surface of the uranium tailing pond needing to be treated through the lifting device and the moving device, microwaves output by the microwave generator can directly act on the beach surface, and the purposes of high-temperature sintering and solidification of the beach surface of the uranium tailing pond are achieved. According to the invention, during microwave treatment of the beach surface of the uranium tailing pond, the microwave heating system is used for carrying out layering, direction dividing and solidification treatment on the beach surface of the uranium tailing pond, and finally sintering treatment of the whole beach surface is achieved. In addition, the volume reduction effect is achieved through sintering treatment, sintering is conducted in a microwave heating mode, the interior and the exterior of the material can be heated at the same time and warmed at the same time without any heat conduction process, the heating speed is high and uniform, and the equipment has characteristic of being high in temperature increasing speed, short in sintering time, high inpenetrability, high in energy utilization rate, less in generated secondary waste and the like.

Composite sintering apparatus and method of 3D printing metal entity

Abstract: The invention discloses a composite sintering apparatus and method of a 3D printing metal entity. The composite sintering apparatus comprises a sintering furnace, the furnace is provided with a cavity, and an infrared heating device is arranged in the cavity; the composite sintering apparatus further comprises a microwave heating device and a cooling device, and the microwave heating device comprises magnetrons distributed on the cavity; the cooling device comprises a cold water pipe distributed on the surface of the cavity and an inert gas pipeline communicated with the cavity.
