Abstract

The invention discloses novel graphite electrode manufacturing technology, and manufacturing equipment thereof. The novel graphite electrode manufacturing technology comprises steps of 1, material preparation; 2, calcining; 3, grinding; 4, stirring; 5, rolling; 6, primary filtering tank immersion; 7, roasting; 8, moulding; 9, secondary filtering tank immersion; and 10, graphitization. The manufacturing equipment comprises a filtering tank main body; the filtering tank main body is of a box type structure with an upper end opening; locking mechanisms are symmetrically arranged on pair of internal side surfaces of the filtering tank main body, and aeration pipes are symmetrically arranged on the other pair of internal side surfaces of the filtering tank main body. According to the novel graphite electrode manufacturing technology, moulded graphite electrode green compacts are subjected to two times of filtering tank immersion, and the manufacturing equipment is adopted, so that anti-oxidation layers are easily formed on graphite electrode green compact surfaces, contact of graphite electrode surfaces with oxygen in the air is prevented, graphite electrode oxidation resistance is improved, graphite electrode oxidation weight loss is reduced, and graphite electrode stable state is improved further.

Description

technical field

[0001] The invention belongs to the technical field of graphite products, and in particular relates to a manufacturing process of a novel graphite electrode and manufacturing equipment thereof. Background technique

[0002] With the continuous development of science and technology, graphite electrodes, as high-temperature-resistant conductive materials, are widely used in: electric arc steelmaking furnaces, submerged electric furnaces, resistance furnaces, and the production of special-shaped graphite products.

[0003] Graphite electrodes are mainly made of petroleum coke and needle coke, coal tar pitch is used as a binder, and are made through calcination, proportioning, kneading, pressing, roasting, graphitization and other processes. Conductors for heating and melting can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to their quality indicators. The increasing complex...
