The electrodes graphitized d 150-250. The electrodes graphitized by wholesale

In the modern industry electrodes coal and the electrodes graphitized find broad application in electrothermal, metallurgical and electrochemical productions.

In all electrothermal and in a number of metallurgical processes deal with electric heating for creation of required temperatures. It is known that having warmed with electric current it can be made or directly (direct heating), or indirectly (indirect heating), in arc furnaces, in resistance furnaces and in induction furnaces.

In each of these cases justifications for the choice of current-carrying conductors to a reactionary zone of the electrothermal unit are required. If it is about arc electric ovens or about moshchkny resistance furnaces of type carborundum, then first of all there is a question concerning the choice of material which, being a conductor, could work in hot conditions. Impose a number of requirements to such provodknik:

- fire resistance;

- inertness concerning chemical reactions and weak oxidability;

- high conductivity;

- low heat conductivity;

- mechanical strength;

- low cost.
