A high-speed highway in the design encounters many problems, for solution of which it is necessary to find best ways. One these problems overheating wire contact network (CN) when passing through neutral insert. The authors propose an insulating connection device (ICD) CN, will allow avoid occurrence electric arc, and, consequently, and subsequent failure wire. ICD CN a set resistances that cha...

Aluminum alloy 6201 is a wrought, heat-treatable alloy, which used in electricity transmission and distribution lines. The processed commercial continuous casting rolling system, includes series of in-line thermomechanical processes involving hot working, quenching, cold working artificial aging. In this study following the subjected to solution heat treatment at 510 °C for an hour, quenched ic...

The production of clean steel involves the controlling, elimination, or modification of nonmetallic inclusions. In Al-killed steels, alumina is the main type of inclusion. Calcium treatment, by wire feeding, is commonly used to modify solid alumina inclusions to calcium aluminates, which exists in a fully or partially liquid phase. Liquid inclusions can improve steel castability, but make inclu...

Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

Power properties of unbalanced linear time-invariant (LTI) loads in three-phase three-wire circuits at asymmetrical and nonsinusoidal supply voltages are investigated in this paper. It is demonstrated that the supply current of such loads can be decomposed into Currents’ Physical Components (CPC), associated with distinctive physical phenomena in the load. The power equation is developed and it...

in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...
