High-temperature graphitization furnace negative electrode sealing filler, and preparation method thereof
The invention discloses a filler for sealing a negative electrode of a high-temperature graphitization furnace. According to the invention, the characteristics of clay, bentonite and ultrafine powderare utilized to ensure the workability of a sealing filler, and silicon carbide, carbon black or graphite and other antioxidant components are added into the filler and can react with air preferentially to ensure that the negative electrode of a electrode is not oxidized by [O] in the air; the high-temperature reaction characteristics of kyanite, andalusite, quartz, MgO and other components in thefiller ensure the high-temperature expansion performance of the filler to block an air channel so as to prolong the service life of the negative electrode; so that the sealing filler can prolong theservice life of the high-temperature graphitization kiln.
本发明公开了一种用于高温石墨化炉负极密封的填料，本发明利用粘土、膨润土、和超细粉的特性保证了密封填料的可易于施工性，填料中添加了碳化硅、炭黑或石墨等抗氧化组分，可优先与空气反应保证了电极负极不被空气中的[O]氧化。此外，填料中的蓝晶石、红柱石、石英、MgO等组分在高温的反应特性保证了填料的高温膨胀性能，堵塞了空气通道，从而延长了负极的使用寿命。因此密封填料可以提高高温石墨化炉窑的使用寿命。
