Reel control cable and preparation method thereof

Abstract

The invention provides a reel control cable and its production method. The reel control cable includes a wire core unit group, an outer sheath, a calcined glass fiber and mica composite tape and a stainless steel braid layer; the wire core unit group includes an 8-core control wire Core, center core, inner sheath and canvas reinforcement layer, the control wire core is twisted around the center core core to form a cable, the outer side is extruded with an inner sheath, and the outer side of the inner sheath is wrapped with a canvas reinforcement layer; there are 4 core unit groups in parallel Place it evenly, extrude the outer sheath on the outside, wrap the calcined glass fiber and mica composite tape on the outside of the outer sheath, and wrap the stainless steel wire braid on the outside of the calcined glass fiber and mica composite tape, and the cross section of the reel control cable is flat. The above-mentioned cables are processed through the steps of filling the core with insufficient sulfur, twisting into a cable, extruding the sheath, and secondary vulcanization. The reel control cable provided by the invention has excellent temperature-resistant and wear-resistant properties, effectively prevents molten steel from splashing, and is widely used in industrial mobile machinery such as transporting molten steel tanks in large-scale steelmaking plants.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a reel control cable used for lifting equipment. Background technique [0002] Steel mills transport steel sports cars, large cranes and other industrial hoisting machinery all use cables for power supply. As the main artery of these equipment, cables should have better torsion resistance, greater tensile strength and higher temperature resistance. And it can meet the technical needs of preventing molten steel from splashing, long service life, small bending radius, soft cable and easy to drag. In practice, none of the existing cable structures can satisfactorily meet the above-mentioned requirements at the same time. Those skilled in the art need to use creative thinking to further improve the structure and process of the cable to overcome the above-mentioned defects. Contents of the invention [0003] The object of the present invention is to provide a flat reel con...
