Specification of DIA 550 UHP graphite electrode and nipple
Tolerance of Graphite Electrodes(UHP550)
Guidance of Using
Being hard and brittle ,artificialgraphite electrode shall be specially handled.Proper operationg may reduce the consumption and cost.
1. Professional tools should be used for hoisting graphite electrodes. It is strictly forbidden to use a crowbar to prevent impact damage during handling.
2. Graphite electrodes are prohibited from rain, snow and water, and should be kept dry. If it is found to be damp, it should be dried before use, the temperature should not exceed 100 ºC, and the drying time should not be less than 48h.
3. Do not stack near debris such as clay, slag, etc., so as not to pollute the surface of the graphite electrode and affect the conductive effect.
4. Before the graphite electrode is connected, carefully check whether the electrode connector hole is intact, whether the connector thread is damaged, and whether the connector bolt is lost. When the electrode is lifted, the electrode connector thread of the ground terminal should be prevented from being damaged.
5. Dust and debris in the joints and joint holes should be blown dry with compressed air.
6. Graphite electrodes must be tightly connected, and no tilt is allowed during connection. Torque wrenches should be used to prevent excessive force or too small, and the gap is not greater than 0.4mm.
7. The electrode holder should be clamped, not loose and in good contact, and no arc should be generated. Otherwise, the connection will be reddish, oxidized, thinned and broken.
8. If the electrode is lifted with a metal lifting plug, the thread in the joint hole must not be damaged. After lifting, the lifting plug should be unscrewed to prevent dust and debris from falling into the joint hole.
9. When the electrode lifting device of the electric furnace is running, it should be kept stable. After the furnace cover is repaired, check whether the furnace cover is positioned correctly. During smelting, refractory materials are used to close the furnace lid to prevent the oxidation of the upper electrode of the flame in the furnace.
10. The holder should be clamped outside the safety wire of the electrode connector hole area.
11. When distributing the molten pool, the big piece is at the bottom and the small piece is at the top. Do not place the charge with poor conductivity on the top. During melting, the unmelted charge should be handled in time to prevent the collapsed material from breaking the electrode.


1. Position of the enterprise:
Continue to write a new chapter of China's carbon industry with the road of sustainable development and international development based on technological innovation, resource conservation and environmental friendliness.
2. The background, history and business scope of the company:
The company (formerly Hailong Technology) was established on January 18, 1999. In September 2006, the private enterprise, Liaoning Fangda Group Industrial Co., Ltd. successfully obtained 51.62% of the company's equity through public bidding. The company was successfully transformed into a private holding company. In order to avoid competition in the industry, the company acquired part of the shares held by the controlling shareholder Fushun Carbon Co., Ltd., Hefei Carbon Co., Ltd., and Chengdu Rongguang Carbon Co., Ltd. to integrate carbon production resources. 
On September 28, 2006, Liaoning Fangda Group Industrial Co., Ltd. successfully bid for 51.62% of the shares of Hailong Technology Company held by Lanzhou Carbon (Group) Co., Ltd. and became the holding company of Hailong Technology Company. After the approval of the State Administration for Industry and Commerce, the company name Changed to Fangda Carbon New Material Technology Co., Ltd., and transferred the holding shares of Fushun Carbon Co., Ltd., Chengdu Rongguang Carbon Co., Ltd., Hefei Carbon Co., Ltd. held by Liaoning Fangda Group Industrial Co., Ltd. Big Carbon Company. After the completion of the transfer, Fangda Carbon Company became the leading professional manufacturer of carbon products in China and the world.
3. The core advantages of the enterprise:
Fangda Carbon Company has a full set of equipment for the production of carbon products at the international advanced level. It has successively imported electric heating kneaders, secondary roasting tunnel kilns, electrode cleaning machines, high-pressure impregnation, and electrode combination processing machine tools from the United States, Japan, and Germany. The key equipment, especially the fully automatic batching 40MN press equipment imported from Japan, is one of the only two most advanced production lines in the world.
4. Successful cases: The products are sold in more than 30 provinces, cities and autonomous regions across the country, and exported to more than 40 countries and regions on five continents. Based on the quality of experts and professional services, we will carefully serve our customers and strive to open up new markets.
5. Reasons for choosing a company:
The quality adopts ISO9001 for the whole process of quality control, and the testing and analysis room has passed CNAS certification. More than 50 new products / new technologies have passed national, provincial and ministerial-level appraisal, and 44 items have received national and provincial-level awards, including 12 national silver awards and 22 high-quality product awards from the Ministry of Metallurgy. CNAS laboratory accreditation certificate, ISO9001 quality system, ISO14001 environmental system, OHSAS18001 occupational health and safety management system certificate, etc., The overall technological capability has reached the international advanced level.
