The invention provides a high-temperature sintering and magnetic core nitrogen charging rapid cooling device, and relates to the technical field of sintering cooling devices. The high-temperature sintering and magnetic core nitrogen charging rapid cooling device comprises a sintering furnace and a furnace door, wherein a first partition plate and a second partition plate are vertically arranged inthe sintering furnace, and the sintering furnace is divided into three sintering chambers by the first partition plate and the second partition plate; a plurality of supporting plates are arranged inthe three sintering chambers, and magnetic core blocks are placed at the upper ends of the supporting plates; a plurality of ventilation pipes are connected to the side walls of the first partition plate and the second partition plate in a penetrating mode; and the opposite ends of the ventilation pipes are provided with gas storage pipes; and the gas storage pipes are connected with nitrogen storage tanks. The defects in the prior art are overcome by the device, the design is reasonable, the structure is compact, the magnetic core blocks in the different sintering chambers in the sintering furnace can be rapidly and effectively cooled, the cooling speed is high, the cooling effect is good, the nitrogen consumption is less, and the cooled nitrogen can be used for heat recovery to save resources.
