Aggregate: 75-80% electrically calcined coal
Only a few electrically calcined coal are suitable for the production of high quality Electrode Paste.
Cylindrical electric Paste from Ningxia Hongyuan Huida Industrial Co.,Ltd has strict production process control and quality control.
Coal pitch:20-25%
Coal pitch is normal bonder for carbon product process . Cohesiveness is very important indicator
Coal pitch softening point(Ring-and-ball method)
Can be combined with different furnace types of customers to provide matching electrode paste.
Electrode Paste type:
Cylindrical Electorde Paste
