In this paper, the computational method, process and requirements were given.The uniformity of the mechanical strength of the graphite electrode is essential... ...
Prospect of graphite material in aerospace
1 Brush materialBrushes are mainly used in various engines, converters and motors, etc., which require good electrical conductivity, wear resistance and commutation function. There are two main types of electric brushes. One is graphite brushes made of resin or coal tar pitch as a binder and graphite powder and metal powder as materials, also called colored brushes; the other g... ...
Application of graphite material in aerospace
The application and suggest of development of graphite materials in aerospace are briefly introduced. As a non-metallic resource mineral, graphite is widely used in the aerospace field due to its self-lubricating properties, easy forming and processing, good thermal conductivity, thermal stability, and stable chemical properties. Such as sealing materials, throat lining materia... ...
Measures for carburization behavior of low-carbon steel during smelting process
1 Measures taken to increase the carbon of low-carbon steelApply the bottom-level event analysis results, combined with the controllable status and difficulty of the smelting process, and take measures as follows:(1) Adjust the inclination angle of the conductive arms so that the three-phase inclination angle of electrode ABC is the same, to view graphite electrodes information... ...
Explore of carburization behavior of low-carbon steel during smelting process
From the argon bottom blowing flow rate and bottom blowing angle, it can be seen that the bottom blowing flow rate and bottom blowing angle of argon also directly affect the fall of the graphite electrode hole wall, and the he mass of electrode hole wall shedding is ＞ 4 kg. As the ferroalloy and refining package walls are less carbonized, they are not considered in the fault tr... ...
Analysis for carburization behavior of low-carbon steel during smelting process
Analysis for carburization behavior of low-carbon steel during smelting processThe reasons of carburization of low - carbon steel during the refining process were analyzed by applying the fault tree theoretical analysis method. The improvement measures including adjusting the inclination angle of the conductive arm to balance the reactance of three-phase current and reduce the ... ...
