Full-automatic production method for graphite electrode antioxidation treatment by using antioxidant liquid

Abstract

The invention relates to a full-automatic production method for graphite electrode antioxidation treatment by using antioxidant liquid. The production method comprises the following steps: step 1, placing a plurality of transport devices in the feeding area of a transport track in sequence for waiting for feeding; step 2, feeding a plurality of graphite electrodes into the transport devices by a feeding device; step 3, transporting the graphite electrodes into a jet dust removal device for jet dust removal treatment by the transport devices; step 4, transporting the graphite electrodes subjected to jet dust removal into a spray coating device to be sprayed with the antioxidant liquid by the transport devices; step 5, transporting the graphite electrodes subjected to the antioxidant liquid spraying treatment into a drying device for heating and drying treatment by the transport devices; step 6, transporting the dried graphite electrodes into a packaging area for packaging by the transport devices. The method involved in the invention has the advantages that the degree of automation is high, the production efficiency is high, decontamination treatment on graphite electrode surfaces is thorough, coating adhesion is firm, the consumption of the graphite electrodes can be effectively reduced, and the service life of the electrodes is prolonged.

Description

technical field [0001] The invention relates to a fully automatic production method for anti-oxidation liquid used in anti-oxidation treatment of graphite electrodes, belonging to the technical field of metallurgical production equipment. Background technique [0002] Graphite electrodes are mainly made of petroleum coke and needle coke, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It has good high-temperature performance and low thermal expansion coefficient. , light weight, easy processing and other characteristics, it is a conductive consumable that releases electric energy in the form of arc in the electric arc furnace to heat and melt the charge, and plays an important role in the electric furnace smelting technology. Graphite electrodes are continuously consumed during the smelting process, which mainly includes three aspects of consumption: one is the high temperature sublimation caused...
