It is numerically equal to the resistance of a conductor with a length of 1m and a cross-sectional area of 1m2 at a given temperature, reducing consumption in use. Usually measured by voltage drop method, the size of resistivity can measure the graphitization degree of graphite electrode, the lower the resistivity of graphite electrode, the higher the thermal conductivity, the better the oxidation resistance.<\/p><p><strong><span style=\"color: #808000;\">\u25cf<\/span> Density of volume<\/strong><br \/>Increasing bulk density is beneficial to reduce porosity, improve mechanical strength and improve oxidation resistance. However, if the bulk density is too large, the thermal shock resistance will decrease. Therefore, other measures should be taken to make up for this deficiency. Such as increasing the graphitization temperature to increase the thermal conductivity of the electrode and using needle coke as raw material to reduce the thermal expansion coefficient of the finished product.<\/p><p><strong><span style=\"color: #808000;\">\u25cf<\/span> Mechanical strength<\/strong><br \/>Mechanical strength of graphite electrode is divided into compressive, flexural and tensile strength of 3 kinds, the main determination of flexural strength, flexural strength is the graphite electrode in use and break related performance indicators. In the electric furnace, when the electrode and the non-conductive object contact, or due to the collapse of the collision, strong vibration and other reasons, the graphite electrode often has the risk of being broken, the graphite electrode with high flexural strength is not easy to be broken.<\/p><p><strong><span style=\"color: #808000;\">\u25cf<\/span> Modulus of elasticity<\/strong><br \/>Elastic modulus is an important aspect of mechanical properties. It is an index to measure the elastic deformation ability of materials, and refers to the stress-strain ratio within the elastic deformation range.

Ordinary power graphite electrode, using ordinary grade petroleum coke production, its physical and mechanical properties are low, such as high resistivity, large linear expansion coefficient, poor thermal shock resistance, so the allowed current density is low.<\/p><p>High power graphite electrode using high quality petroleum coke (or low grade needle coke) production, its physical and mechanical properties are higher than ordinary power graphite electrode, allowing a larger current density. Ultra-high power graphite electrodes must be produced using high grade needle coke. The joint quality of high-power and ultra-high-power graphite electrodes is particularly important. Not only the electrical resistivity and linear expansion coefficient of the joint billet are smaller than the electrode body, but also the joint billet should have higher tensile strength and thermal conductivity.
