Product Detail

Overview

The Ultra High Power UHP Graphite Electrode is produced by 100% high quality imported needle coke, advanced production equipment and technology, and is produced in strict accordance with the world class standard, the Ultra-high Power (UHP) Graphite Electrode has lower resistivity, better electrical conductivity and higher mechanical strength. The Graphite Electrode Nipples are made of 100% imported needle coke with three times impregnation and four times baking process.The product quality has approached or reached the world-class standard, which can meet the needs of various Ultra-high Power (UHP) Electric Arc Furnace (EAF) and Ladle Refining Furnace (LRF) steelmaking.

Features

Higher purity, higher density, and perfect chemical stability

Low coefficient of thermal expansion, resistance to cracking, broken and thermal shock

High mechanical strength and lower electrical resistance

Products Transportation and Installation Introductions:

The Electrodes should be kept in a clean, drying place and avoid vibrations and collisions. It should be dried before use.
(2) When installing the joint, please clean the hole with the compressed air, then carefully screw the joint and not damage the thread.
(3)When connecting electrodes, the two electrodes should be cleaned with compressed air when they are 20-30mm apart.
(4)When using a wrench to connect the electrode, it should be completely taut to the specified position so that the gap between the two electrodes is not less than 0.05mm
(5)To avoid the electrode fracture, please avoid the insulation block.
(6)To avoid the electrode fracture, please place the bulk block in the upper part.
