GRAPHITE ELECTRODE HOLLOW ELECTRODE

Characters

  1. Special treatment of anti-oxidation dramatically increase service life span at least 5 times more than common anti-oxidation treatment. (national PATENT)
  2. High thermal stability for strict working conditions(dramatic performance of anti-shock-chilling)
  3. Low sulfur and low ash content will not give steel second time impurity.
  4. High strength, high mechanical stability and high accuracy.
  5. Anti-acid and alkali resistant, high chemical stability, prolong service life
  6. Anti-stain, high purity and density.
  7. ISO-9001:2000  TUV & SGS testing report can be provided according to customer’s requirements

We also specially dedicated to process SPECIAL SIZE ELECTRODES (NON-STANDARD) more than normal size.

Product Description

About processing and production

  1. With high performance of Numerical Control Machining Center Lathe any size special shape can be processed according to drawing, and a diversity of 3. high quality material available.
    2. Large stock ensures short delivery time.
    3. Customized size, shape and specifications according to drawing and customer’s requirements.
    4. Customer oriented cost-effective solutions based on your specific applications.

Quality control and after-sales

  1. Strict quality control system, ensuring only qualified cargo can be delivered, dual QC system applied during our processing, each worker is also an inspector for previous working process, and final quality confirmation from QC department.
  2. High frequency of checking, sampling, and analysis during production, and reliable factory inspection report to be issued before shipment by our own lab.
  3. After sales system, including quality assurance, after sales service, and quality problem solving to achieve long term co-operation.

Applications

Widely used in arc furnace (EAF, LF for steel making) and electrochemical furnace (for metallurgical and chemical industry).
