Graphite has good chemical stability. After special processing, graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability, so it is widely used to make heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment. Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper

The main indicators of the quality and performance of graphite electrodes include: bulk density db, resistivity ρ, flexural strength, elastic modulus E, thermal expansion coefficient α and ash content A%. According to the differences between these indicators and different national standards and manufacturing processes, graphite electrodes are divided into three types: ordinary power graphite electrodes

What is roasting? Roasting refers to the technological process of carbonizing coal tar pitch in the process of forming graphite electrode green blank in the protective medium of roasting heating furnace, under the condition of isolating air, and at a certain heating rate. Binder coke is formed by pyrolysis and condensation reaction of coal tar pitch binder

(1) long production cycle. The production cycle of ordinary power graphite electrode is about 45 days, that of ultra-high power graphite electrode is more than 70 days, and that of graphite electrode joint which needs to be impregnated many times is longer. (2) high energy consumption. The production of 1t ordinary power graphite electrode needs to consume about 6000kW

The conditions of forming Graphite Electrodes the electrolytic cell constitute the conditional DC power supply of the electrolytic cell (1) DC power supply (2) two electrodes. Two electrodes are connected with the positive pole of the power supply. Among them, the positive electrode connected with the positive electrode of the power supply is called the anode and

With the increasing complexity of die geometry and the diversification of product application, the discharge accuracy of spark machine is required to be higher and higher. The advantages of graphite electrode are easy to process, high removal rate of EDM and small graphite loss. Therefore, some customers of group based spark machine abandon copper electrode
