Method for antioxidation treatment of antioxidation graphite electrode by using antioxidation liquid

Abstract

The invention discloses a method for antioxidation treatment of an antioxidation graphite electrode by using an antioxidation liquid. The graphite electrode antioxidation treatment method comprises seven steps, and then effective production is carried out through the seven steps during treatment and production, so that graphite electrode oxidation treatment is more efficient. The surface contact surface is cleaned through pretreatment, so that the contact with an impregnation liquid is comprehensive; the impregnation liquid covers the top of an graphite electrode for a certain distance, so that reaction spill is avoided; vacuum pumping is carried out, then no oxygen participates in the reaction, and extra damage in the reaction is reduced because no oxygen participates, so that consumptionof the graphite electrode is effectively reduced, the quality of the whole graphite electrode is improved, and good market competition strength is achieved in market competition; and the impregnationliquid has good environmental friendliness, has a simple preparation mode and low cost, and is convenient to prepare and use at normal temperature, so that extra capital expenditure is reduced.

Description

technical field [0001] The invention belongs to the technical field of related graphite electrodes, and in particular relates to an anti-oxidation treatment method for an anti-oxidation liquid for an anti-oxidation graphite electrode. Background technique [0002] Graphite electrodes are mainly made of petroleum coke and needle coke, and coal tar pitch is used as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They release electric energy in the form of arcs in electric arc furnaces. The conductors for heating and melting the charge can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to their quality indicators. [0003] The main raw material for graphite electrode production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and pitch coke can...
