Our company
Hengtai Group, one of the leading enterprises in China Carbon Industry, has been specializing in technology research and development, manufacturing and sales of graphite electrodes, carbon additive and other carbon products. Graphite electrodes are widely used in electric arc furnace and ladle furnace for steel production, ferroalloy production, silicon metal production and smelting processes. In addition to high temperature which can reach up to 3000, our graphite electrodes are featured with lower electric resistivity, lower consumption, lower coefficient of thermal expansion, higher transverse strength, higher elastic modulus and higher oxidation resistance.

How to Choose the Suitable Graphite Electrode Type:

If the Current Density is less than 17 A/cm2you can choose RP. If the Current Density is between 18 and 25 A/cm2, you can choose HP. If the Current Density is above 25 A/cm2UHP should be selected.

Instructions of usage for Graphite Electrode: 

Notes of usage: 

1. The electrodes should be stored in the clean and dry places, and should be avoided for shock and collision. Before used, the electrodes should be baked to dry.

2. To Place the nipples, first use compressed air to clean the hole, then carefully screwed the nipples into it (do not damage the thread). 
3. To connect the electrodes, when there's 20-30mm distance between the two electrodes, using compressed air to clean the two extremes. 
4.When use the wrenches to connect electrodes, should be fully tighten to specified torque. 
5.To avoid electrode broken, please remove the insulating material in the furnace. 
6.To avoid electrode broken, please place the big block in the lower and smaller block at the upper.
