Vacuum arc descaling technique is a dry and green substitute for the traditional acid-washing and mechanical cleaning technique widely used in the metallurgical industry. It mainly utilizes the high energy density property and the selective motion property of cathode spots. In this paper, the influences of different factors, mainly the vacuum arc circuit, the protect gas pressure, and the electrode...
Vacuum arc descaling technology is a new dry and green descaling technology that was put forward in recent years. The technology, which is environmental friendly, takes advantages of the high energy density and the selective movement of cathode spots to remove the oxide layer on cathode surface. In this paper, the characteristics of cathode surface in descaling are studied experimentally. Experimental...
It has been investigated that removing oxide layer on metal surface by vacuum arc can be a “green” substitute for traditional acid-washing technique and mechanical cleaning technique widely used in metallurgical industry, which is harmful to environment. In this paper, the effect of vacuum arc on removing oxide layer on the surface of carbon-steel tube, which was used as the cathode, was investigated...
