Abstract
The invention discloses a special high-temperature-resistant temperature measuring cable for a steel furnace. The cable comprises a sheath insulating layer, a first shielding layer, a first F4 tape, afirst mica tape, a second mica tape, a second shielding layer, a second F4 tape and four conductor assemblies which are sequentially arranged from outside to inside. Each conductor assembly comprisesa nickel-plated wire, an F46 insulating layer, a third mica tape and a braided shielding layer which are arranged from inside to outside, wherein five 0.3 mm nickel-plated wires are adopted as the nickel-plated wires, the four nickel-plated wires are externally extruded with F46 insulating layers which are white, red, black and purple respectively, and the outer diameter of each F46 insulating layer is 1.33-1.37 mm. The special high-temperature-resistant temperature measuring cable is simple in process, convenient to operate and reliable in performance, reduces errors, insulates heat, resistsfire and improves use performance.
Description
Technical field [0001] The invention relates to the field of cable processing; in particular, it relates to a special temperature measuring cable for high temperature resistance of a steelmaking furnace. Background technique [0002] The design of the special temperature measuring cable for high temperature resistance of steelmaking furnace is unreasonable, and its service life is short. It is found that the stability of high temperature resistance is poor during use; the service life is short after long-term use, resulting in high maintenance cost of steelmaking furnace. Summary of the invention [0003] In order to solve the above technical problems, the technical solution of the present invention is as follows: [0004] A special temperature measuring cable for high temperature resistance of steelmaking furnace; comprising a sheath insulation layer, a first shielding layer, a first F4 tape, a first mica tape, a second mica tape, and a second shielding layer sequentially arranged ...
