Production characteristics of graphite electrode

Carbon graphite in the field of electrode production outstanding performance

This paper mainly introduces what is graphite electrode and the production characteristics of graphite electrode, and briefly introduces the manufacturing enterprises of graphite electrode.

 

What is a graphite electrode

 

The graphite electrode is made of petroleum coke, asphalt coke as aggregate and coal asphalt as binder

It is a kind of high temperature resistant graphite conductive material made by calcining raw materials, crushing powder, batching, clay kneading, molding, roasting, dipping, graphitization and mechanical processing, and is called artificial electrode (graphite electrode for short),

Prepared from Natural graphite, which is different from that of Natural graphite

graphite electrodes are mainly used as conductive electrode materials for electric arc furnace.

The output of graphite electrode in China reached 368,300 t, and the graphite electrode export exceeded 100,000 t

 

What are the manufacturing characteristics of graphite electrode

  

(1)long production period/cycle.

The production cycle of ordinary power graphite electrode is 45 days left

Right, the production cycle of ultra-high power graphite electrode is more than 70 days, and multiple immersion is required

The production cycle of the graphite electrode joint is longer.

 

(2)High energy consumption, the production of 1t ordinary power graphite electrode needs to consume electricity

Can 6000kW·h or so, gas or gas thousands of cubic meters, metallurgical coke and metallurgical

Gold coke powder approx. 1t.

 

(3)There are many production processes, including calcining of raw materials, crushing and grinding of powder and ingredients

Mixed kneading, molding, roasting, leaching, graphitization and mechanical processing, and other production needs many special

The construction investment of machine pepper equipment and kiln with special structure is large and the payback period is long.

 

(4)The production process produces a certain amount of dust and harmful gas, need to be picked

Take sound ventilation dust removal and elimination of harmful gas environmental protection measures. ao hui carbon company is one of the leading group companies in China, which mainly produces and operates carbon metallurgical material products and provides quick quotation, reliable quality, competitive price products and delivery service as soon as possible according to industrial standards and customer requirements.
