TECHNICAL PERFORMANCE

1. Precise Control of Extrusion Speed

The hydraulic system drives main plunger cylinder to accurately control extrusion speed of graphite electrodes and to ensure quality of graphite electrodes.

2. New Die Design

The design of multi-curve reducing section combined with short transition section die can greatly improve forming density and surface quality of graphite electrode.

3. Vacuum System

Vacuum system evacuates the paste during both the pre-extrusion and extrusion process to fully emit pitch fume and to improve forming and finished product quality, to get short pre-extrusion time and efficient production.

4. Automatic Synchronous Shearing Device

Which avoids internal layering, expansion, cracking and other defects of graphite electrodes caused by fixed type shearing device and guarantees quality of graphite electrodes and improves production efficiency.

5. Accurate Temperature Control of Material Chamber And Die By Stages

Material chamber and dies are heated with accurate temperature control by stages to guarantee stable quality of graphite electrode.

6. Quick Return Assisted By Auxiliary Cylinder

Auxiliary cylinders are responsible for quick return movement of the extrusion rod to improve work efficiency.

7. Fixed Type Single Material Chamber

Simple structure ensures the cost saving of equipment, infrastructure and supporting facilities, and reliable operation and easy maintenance.

8. Hydraulic Control System

Domestic and overseas famous cartridge system, valves and filtering systems and pump station adopting independent circulation system are applied to guarantee continuous stable and reliable operation of hydraulic system. Flanged pipe connection guarantees reliable sealing and zero leakage of hydraulic system pipes under multiple high pressure circulations.

9. PLC Automatic Control

PLC automatic control is applied to set key process parameters and to automatically control the process, the system runs automatically which guarantees production process parameters and quality stability, productivity is improved and production cost is reduced.
