1. We produce,prcess,supply ad export all kinds of Carbon Electrode paste,Graphite electrode paste for over 10 years and accumulaed sophiscated experience and expertise in this field.
Welcome to contact us for detailed information.
2. Electrode paste is a kind of important comsumptive,electric conductive material for ferro alloy furnace and calcium carbide furnace,also called self baking electrode and can be categorized into two groups based on different recipes:THD&THM,
and electrode paste for chemical industries.
Electrode past materials used are anthracite coal,foundry coke,petroleum coke,graphite scrap through drying,mixing and then crushed together with adhesives---coal tar,pitch. It can be used as self baking electrode for alloy smelting furnaces.
3. THD(Standard/Non-standard Paste): standard paste used for open type ferro alloy furnace and and calcium carbide furnace with small and medium size. Non-standard paste adopted in open large scaled calcium carbide furnace.
THM:suitable for closed or enclosed type ferro alloy furnce, calcium carbide furnace, and other metallurgical furnaces.
4. Characters:
a. Adapt to high temperature, low heat thermal expansion rate
b. Lower resistivity a thus lowered power energy loss during metallurgical process
c. Small porosity thus decreased electrode's oxidation when heating
d. Better mechanical strenghth to avoid breaking electrode due to mechanical and electrical factors
