Electric drive cable of hot furnace steel transfer trolley and manufacturing method of electric drive cable

Abstract

The invention discloses an electric drive cable of a hot furnace steel transfer trolley and a manufacturing method of the electric drive cable. The electric drive cable comprises an outer protection layer, an isolation layer, a filling layer and three-phase cable cores; the three-phase cable cores are wrapped with the isolation layer; the outer protection layer wraps the isolation layer; the filling layer is arranged among the three-phase cable cores and in a gap between the three-phase cable cores and the isolation layer; each cable core comprises a conductor layer and an insulating layer wrapping the conductor layer, wherein the conductor layer is made of a nickel-plated soft copper conductor material, the insulating layer is made of a magnesium oxide high-temperature-resistant belting material; the isolation layer is formed by overlapping and wrapping a plurality of layers of ceramic mica wrapping tapes; the filling layer is composed of dust-free rock wool ropes; the outer protection layer is formed by interlocked armoring of nickel-plated steel strip metal; and the outer protection layer is coated with a graphite layer or metallic paint. The cable is long in service life, high in safety performance and capable of meeting the use requirements of the hot furnace steel transfer trolley. The manufacturing method of the cable is simple and easy to implement.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an electric drive cable for a hot furnace steel transfer vehicle and a manufacturing method thereof. Background technique [0002] In the process of modern steel manufacturing process, how to send the hot molten steel refined in the converter to the next continuous casting or mold casting work area, generally adopt the automatic conveyor belt device to transport to the next process, but the steel converter of modern large-scale steel plants has a large production capacity , generally can produce (200-400) tons, large-scale steel converters have higher output efficiency and lower energy consumption, but the nearby conveyor belts cannot digest the limited production capacity, most of the molten steel needs to be transported to scattered work areas or workshops, in order to reduce energy Loss, to avoid a large cooling, or solidification caused the molten steel tank and molte...
