Graphite heating body protection process for vacuum sintering furnace
The invention discloses a graphite heating body protection process for a vacuum sintering furnace, which comprises the following steps of: preparing boron nitride molten liquid constantly, keeping thestirring state of the molten liquid, performing heating by using the sintering furnace, stopping heating after the heat preservation time reaches specified 1 hour, naturally performing cooling, opening a furnace door when the temperature is 150-200 DEG C, and taking 2L of boron nitride molten liquid; connecting a measuring cup containing 2L of boron nitride melt with a spray gun head, enabling aworker to hold the spray gun head by hand and sprays the graphite heating body, enabling the boron nitride melt to heated to evaporate water quickly, and forming a white boron nitride protective layeron the surface of the heating body. According to the invention, operation is convenient and fast, maintenance is convenient, the working efficiency is higher, and the protective layer is uniformly and firmly adhered to the heating body.
本发明公开了一种用于真空烧结炉的石墨发热体保护工艺，常备氮化硼熔液并保持熔液的搅拌状态，使用烧结炉进行加热，保温时间到达指定的1h后，停止加热，进行自然降温，150℃至200℃时，开启炉门，取2L氮化硼熔液，将盛有2L氮化硼熔液的量杯与喷雾枪头连接，工人手持喷雾枪头，对石墨发热体进行喷涂，氮化硼熔液受热水分迅速蒸发，在发热体表面形成一层白色的氮化硼保护层，本发明实现了作业便捷方便保养，工作效率更高，保护层均匀粘附发热体且粘附牢固的功能。
