(1) Material preparation and weighing: Weigh the graphite electrode joint bolt to provide qualified materials to be processed;

(2) Preparation and heating of the immersion solution: the composition of the immersion solution includes industrial boric acid (h↓[3]bo↓[3]) 18-27%, industrial borax (na↓[2]b↓[4]o↓[ 7]) 7-15%, after mixing, adjust it into liquid with water, and heat it after preparation;

(3) Immersion treatment: Put the prepared graphite electrode joint bolt into a vacuum tank for sealing, use a vacuum pump to vacuum, and pour the heated immersion liquid into the vacuum tank for immersion. During the immersion process, the immersion liquid Supplement appropriately when the concentration drops;

(4) Second weighing: After the immersion electrode treatment, open the vacuum tank, take out the graphite electrode joint bolt after immersion, and drain the immersion liquid. The weight of the electrode after immersion is more than 10%;

(5) Drying treatment: the graphite electrode joint bolt after immersion is dried so that the moisture content of the electrode is not higher than 0.5%;

(6) Three times of weighing: After drying, weigh the graphite electrode joint bolt again, so that the weight increase is more than 3% of the weight before immersion;

(7) Finished product processing: The graphite electrode joint bolt processed above can be processed into a standard shape as required. The graphite electrode joint bolt processed above can be processed into a standard shape as required.
