CNC machine tools that can machine graphite electrodes

Graphite electrode refers to a kind of resistant material made of petroleum coke and pitch coke as aggregate, coal tar pitch as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High temperature graphite conductive material, called artificial graphite electrode (referred to as graphite electrode), is different from natural graphite electrode prepared by using natural graphite as raw material.

(1) For electric arc steelmaking furnace

Electric furnace steelmaking is a major user of graphite electrodes. my country's electric furnace steel production accounts for about 18% of crude steel production, and graphite electrodes for steelmaking account for 70% to 80% of the total amount of graphite electrodes. Electric furnace steelmaking is to use graphite electrodes to introduce current into the furnace, and use the high-temperature heat source generated by the arc between the electrode end and the charge to smelt.

(2) for submerged thermal electric furnace

The submerged arc furnace is mainly used for the production of industrial silicon and yellow phosphorus. Graphite electrodes are required for submerged thermal electric furnaces with high density. For example, about 100kg of graphite electrodes are consumed per 1t of silicon produced, and about 40kg of graphite electrodes are consumed per 1t of yellow phosphorus produced.

(3) For resistance furnace

The graphitization furnace for the production of graphite products, the furnace for melting glass and the electric furnace for the production of silicon carbide are all resistance furnaces. In the furnace head wall of the upper part, the graphite electrodes used here are not continuously consumed.

(4) For the preparation of special-shaped graphite products

The blanks of graphite electrodes are also used for processing into various shaped graphite products such as crucibles, molds, boats and heating elements. For example, in the quartz glass industry, 10t of graphite electrode blanks are required to produce 1t of fused tubes; 100kg of graphite electrode blanks are required to be produced for each 1t of quartz bricks.
