Russia-Continuous Casting Machine Technology Seminar

Novolipetsk Steel, or NLMK, is one of the four largest steel companies in Russia. NLMK’s share of domestic crude steel production is about 21%. It primarily produces flat steel products, semi-finished steel products and electrical steels. NLMK also produces specialty coated steels, plus high-ductility and micro-alloyed steels. 、   Background & Visiting Target Last year the metallurgic plant…

Classification of Graphite Electrodes

(1)General power graphite electrode Graphite electrodes with current density less than 17A/cm 2 are allowed to be used in ordinary power electric furnaces such as steelmaking, silicon and yellow phosphorus. (2)Antioxidant Coated Graphite Electrode Graphite electrodes are coated with an antioxidant protective layer (graphite electrode antioxidant). The formation of a protective layer which can conduct…

Reasons for the consumption of graphite electrode in electric furnace steelmaking and corresponding solutions

There are three reasons why the graphite electrode for electric arc furnace causes loss during use Side oxidation The side loss of the electrode is due to the action of oxygen and graphite in the furnace gas to generate carbon monoxide or carbon dioxide which consumes 50 to 70% of the total electrode consumption,the side…

what is the graphite electrode?

Graphite electrode refers to petroleum coke, asphalt coke as aggregate, coal tar pitch as binder, through raw material calcination, crushing milling, compounding, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High-temperature graphite conductive material, called artificial graphite electrode (abbreviated as graphite electrode), is distinguished from natural graphite electrode prepared by using natural graphite as raw…
