uhp 500mm graphite electrode with low resistivity for eaf furnace

The influence of graphite dust on machine tools

Graphite is a heterogeneous brittle material with microscopic defects. It has the characteristics of structural inhomogeneity, porosity and brittleness, which have an important influence on the processing of uhp 500mm graphite electrode with low resistivity for eaf furnace. Research at home and abroad has shown that the cutting of graphite materials is very different from metal materials: metal materials are stripped or nodular cut through plastic deformation to achieve material removal; graphite materials are formed by brittle fracture to generate chipping particles. Or dust to achieve.

Graphite dust has a great influence on the service life of the machine tool and the machining accuracy of uhp 500mm graphite electrode with low resistivity for eaf furnace. If graphite dust enters the spindle, it will cause unstable clamping, shorten service life, process surface roughness, increase downtime, reduce workpiece machining dimensional accuracy and spindle bearing service life. Machine tools generally have a protective cover made of transparent materials for the observation of the processing process. If the protective cover is contaminated by graphite dust, the visibility will be reduced, which will affect the sight of the operator and cause more waste. Graphite dust with low purity contains silicon carbide. Silicon carbide is a high-hardness grinding powder. Intrusion into the machine will aggravate the wear of the sliding surface of the machine, and entering the feed system will cause the wear of the lead screw and linear guide; while the purity is high The graphite is a good conductive material. Graphite dust entering the data line interface will affect data transmission, entering the CNC system will affect its sensitivity and reliability, and more seriously, it will cause a “short circuit” of the electrical system and cause a production accident.

When the carbon company was founded, it established the development strategy of “technology, innovation”, adhering to the business philosophy of “service first”, after the uhp 500mm graphite electrode with low resistivity for eaf furnace process was improved, the quality was perfect, and the market was developed, carbon has become a Jin, Graphitization processing enterprises in Hebei and Mongolia. The main business includes graphite electrode, Shijiazhuang graphite electrode, and Datong silicon carbide.
