From room temperature to 2500℃, the mechanical strength ofgraphite electrodeincreases with the increase of temperature. At 2500°C, the mechanical strength is about 1-2 times that of room temperature.The reason why the mechanical strength of graphite products increases with the increase of temperature can be explained as follows: 1. Graphite products do not produce local plastic deformation at low temperature, so even if a lower load is applied, it will cause stress concentration fracture.Howev

While the eye-catchingultra-high power (UHP) electrodesthat shine in electric arc furnaces (EAFs) have always been a central component of melt shop operations. They have rarely been the focus of attention in the steel products market, where they play a critical role in the upstream part of the process.That changed when the steel industry realized there was a shortage of UHP graphite electrodes, and their prices soared as steelmakers scrambled to secure supplies. Some steel production was cut as

Graphite electrodeAgraphite electrodeis nothing more than a sharp graphite rod, taken from a pile, subject to a support conductor for the current, a copper tube, and a plastic handle at a reasonable distance, a PVC pipe. The handle should be far enough away so that it does not soften it by overheating. In any case, it is clear that PVC is the worst plastic that can be used for this purpose, but it does exist.This is the sheet metal welder for almost any metal. It requires no input material and a

One of the main reasons people have historically used copper in electrical discharge machining (EDM) is because it is cleaner in their work environment, but is that where the material advantage lies?With over 70% of today's global market choosing graphite electrode materials over copper, the question is why choose graphite over copper for your EDM application? This article examines the differences between the two materials and outlines the reasons why graphite is best suited for your EDM app
