Background technique
Furnace outer refining technology is that 20th century ladle furnace (ladle arc refining furnace) is a kind of in vacuum or non-
The furnace outer refining technology of electric arc heated is utilized under vacuum condition.It is that the molten steel just refined in general converter is placed in special-purpose steel
It is refined in packet.This technology is Japanese Zhi Gang Co., Ltd., Datong District in 1971 in research ASEA-SKF, refining furnace, VAD
On the basis of the refining techniques such as furnace, VOD method and equipment, using the mature experience of other method of refining, keeps away its difficult point and develop.
One of conventional process is electric arc heated technology in furnace outer refining technology, i.e., by electrode special, to molten steel after energization
The technology that electric arc heats molten steel is generated, the electrode generally used is graphite electrode, it is formed by connecting successively by one, every section charcoal
The both ends of electrode are respectively arranged with the female internal screw thread being mutually matched, male connector external screw thread, by the male and female of each section carbon resistance rod when use
Head is opposite to be screwed.Carbon resistance rod in smelting furnace in use, except with electric arc generation and by electrical and mechanical loss in addition to,
Simultaneously because high temperature, high hot atmosphere when smelting furnace operation, carbon resistance rod outside wall surface are gradually oxidized loss.Under normal circumstances,
It is just very big in the oxidization burning loss of 1100 DEG C or so carbon resistance rods, and it is easy to happen loss of sheet accident, lead to consumption of electrode height.And once
Loss of sheet accident occurs, resumes production and needs more a large amount of electric power of consuming.
It is mainly electrode tip between electrode and molten steel through analysis and research it is found that under normal condition, i.e., most with molten steel distance
Close place electric discharge, and discharge scenario then seldom occurs for electrode side, the loss of electrode side mainly oxygen in the case of a high temperature
Change loss.
China State Intellectual Property Office is proposed in the Antioxidant carbon electrode (201878362 U of CN) of Granted publication in 2011
A kind of Antioxidant carbon electrode, this is using a kind of electrode with antioxidant coating is proposed in new patent, although can be to electrode
Ontology generates certain protection, but still remains following disadvantage: it is handled between high temperature coating and electrode body without special binder,
Cause the Antioxidant carbon electrode to be also easy to produce the case where high temperature falls off in use, once falling off, not only will appear height at this
The phenomenon that temperature oxidation, accumulation point can be also formed in use, cause breakage electric discharge to generate electric arc, more exacerbate
The high temperature scaling loss of electrode.
