Steel and iron industry is the important foundation industry of national economy, is the important symbol of national economy level and overall national strength.China is iron and steel production and consumption big country, and crude steel output ranked first in the world in continuous 13 years.Development along with the iron and steel technology, steel industry equipment is also more and more intelligent, requirement to auxiliary equipment is also more and more higher, cable used on the buggy ladle has also had new requirement, promptly require the power cable of electric energy transmitting and the control cable of transmission signals are merged in the cable, so not only saved the space but also reasonably utilized the energy.
The many employings of the used cable of buggy ladle at present five class copper conductors, silicon rubber or the second third glue insulation, silicon rubber or other similar elastomeric body sheaths (whole braided steel wire armouring, count generally is not less than 90%) structures.Though these structures have solved the flexibility of cable, the counter-bending anti-reciprocating motion performance of cable does not obtain real raising, and because cable when introducing the buggy ladle motor, its tie point and buggy ladle are too near, cable surface is very easily fallen in molten steel splash during tapping, thus the scaling loss cable.If in addition because cable adopts whole wire armoring weight too heavy, cable drum is positioned at the middle high vacancy in walking highway section, during the buggy ladle walking, it is dilatory that cable is drawn back and forth in the high-altitude, suffered external force very easily causes the fracture of small bore control cable core, and these faults all can cause the stopping production of the unplanned property of blast furnace, thereby bring great economic loss to steel mill.
The utility model content
In order to adapt to the new demand of used cable on the buggy ladle, also solve the deficiency that the used cable of above buggy ladle exists in addition, redesign according to the structure of its handling characteristics cable.
It is little that carbon fiber complex core has high strength, high-modulus, density as the tensile core of cable conductor, soft, corrosion-resistant, also has good tensile fatigue performance after long-term the use, do not have the generation of overstrain phenomenon, coefficient of linear expansion is little in high temperature and low temperature environment, coefficient of friction is little, conductivity height, stable performance.Hot strength can reach 4900Mpa, is that several times of steel wire reach to tens times.
Concrete structure design of the present utility model is as follows: novel buggy ladle cable, comprise cable core and heat shield layer, described cable core cross-section is round, the center is provided with fills tensile core 5, " five-petaled flowers shape " is arranged with three power cable cores and two control cable cores around it, is provided with squash type inner sheath 4 at skin after power cable core, control cable core and the 5 stranded moulding of filling tensile core; Described heat shield layer is provided with sheath reinforced layer 10 from the inside to the outside successively, oversheath 11, comprehensive thermal insulation layer 12.
The center of described power cable core is provided with the power cable core conductor tensile core 1 that adopts carbon fiber complex core to make.
Described control cable core inside is that three sub-cores are the setting of " product " font, sub-core center has adopted carbon fiber complex core as control cable core conductor tensile core 7, the outer braid of control cable core conductor tensile core 7 has the control cable core conductor 8 of double-deck copper wire, and sub-core outermost layer is provided with control cable core insulating barrier 9.
Described sheath reinforced layer 10 adopts Du Pont's silk braiding.
Described oversheath 11 adopts chlorinated polyethylene rubber.
It is that the high silica refractory fiber cloth of 1.0mm is overlapping wrapped that described comprehensive thermal insulation layer 12 adopts thickness.
Useful technique effect of the present utility model is: 1, adopt carbon fiber complex core both can improve the resistance to bend(ing) energy and the tensile property of core, the while also can be improved the current capacity of power core.
2, the design of control cable core conductor, adopted carbon fiber complex core as tensile core, conductor structure adopts the structure of double-deck copper wire around the carbon fiber complex core braiding, because the copper wire braiding structure is with respect to the bundle structure that tangles, its pitch is littler, core along the line can have long stretching, extension at axis direction when stressed, thereby avoids the stressed equally and problem of premature failure of control cable core and power cable core.Make the control cable core have extremely excellent resistance to bend(ing) energy and tensile property, prolonged the useful life of cable greatly.
3, the sheath reinforced layer adopts Du Pont's silk braiding, count is not less than 30%, Du Pont's silk has high tensile strength, be steel wire 6-10 doubly, proportion is then less than 1/5th of steel wire, this Du Pont silk woven mesh structure, as framework material, extend in all direction, both effectively strengthened the resistance to tension of this cable, guaranteed the requirement of this cable flexibility again.
4, comprehensive thermal insulation layer employing thickness is that the high silica refractory fiber cloth of 1.0mm is overlapping wrapped, and wrapped Duplication is not less than 50%.High silica refractory fiber cloth has the intensity height, good performances such as high temperature resistant, anti-ablation, heat insulation, stable chemical performance, and softening point can use under 900 ℃ of environment for a long time near 1700 ℃, and the utilization of this material can successfully solve the molten steel splash and scald cable.
