With the development of steelmaking technology, ultra-high power graphite electrodes have grown rapidly. In the production of uhp graphite electrodes, each technical link in the production process must be grasped, especially the selection of raw materials, roasting, graphitization, and other links. With the rapid development of industries in various countries, ultra-high power graphite electrodes will play an increasingly important role in electrode production. uhp electrode price. At the same time, graphite electrodes have the characteristics of long production cycle and high energy consumption. Therefore, while continuously improving technology to produce high-quality uhp graphite electrodes, we must also pay attention to reducing energy consumption, reducing environmental pollution, and efficiently using resources.
The Machining Process of UHP Graphite Electrode
UHP graphite electrodes are mostly large-size electrodes, and basically, they are connected by conical joints, so the processing quality is very important. The main measures of ultra-high power graphite electrode and processing technology are as follows.
(1) A high-precision CNC machine tool is used to accurately process the electrode and the joint to ensure a satisfactory tight fit between the electrode and the joint. The perpendicularity of the electrode trunk and the screw surface ensures that the upper and lower electrodes are connected in a straight line, and the outer circle of the electrode and the joint hole are kept concentric. Otherwise, it is easy for the joint to trip and fall during use, or it is easy to break at the connection if there is a slight collision.
(2) High-precision ring gauge detection is used. Detect the machining accuracy of the electrode and the joint to ensure that the tolerance is reasonable.
(3) The performance of the electrode and the joint are matched. Ultra-high-power graphite electrodes are generally large-size electrodes with a diameter of 350mm or more, and they have to withstand the impact of strong current, high temperature gradient, and sudden thermal stress during use. The properties of the joint and the electrode body, such as thermal expansion coefficient, electrical resistivity, mechanical strength, etc., must match, otherwise the joint will break.
Compared with ordinary power electric arc furnace and high power electric arc furnace steelmaking, ultra-high power electric arc furnace has the advantages of short smelting time, low power consumption, and high thermal efficiency, and has developed rapidly. Therefore, the production of ultra-high-power graphite electrode has grown rapidly, and the demand for ultra-high-power graphite electrodes in the steel industry has increased. At the same time, because the use conditions of ultra-high-power graphite electrodes are very harsh, the technical indicators for producing ultra-high-power graphite electrodes have also been improved accordingly. Compared with high-power graphite electrodes (HP) and ordinary graphite electrodes (RP), ultra-high-power graphite electrodes (UHP) require lower resistivity, thermal expansion coefficient and higher flexural strength. To meet the requirements of high-power electric arc furnace steelmaking. In order to produce high-quality ultra-high-power graphite electrodes, technicians must strictly grasp every production process and strive to make technological breakthroughs and innovations.
