Background

With the transfer of international industry and the rapid development of national economy, the steel industry in China has achieved enormous achievements. The iron and steel industry is an industrial industry mainly engaged in industrial production activities such as ferrous metal mineral mining and selecting, ferrous metal smelting and processing and the like, and comprises mineral mining and selecting industries such as metallic iron, chromium and the like, iron making industry, steel making industry and other subdivision industries.

In the steel industry, a converter is a steel making furnace that is widely used. The converter is generally a tiltable cylindrical oxygen-blown steel-making vessel, and the vessel body is cylindrical and is mounted on a rotating shaft frame so as to be rotatable about a rotating shaft. The temperature of molten steel in the converter is usually between 1500 ℃ and 1800 ℃, and the temperature in the converter needs to be detected regularly in order to ensure the product quality. The steelmaking industry adopts throwing bullet formula rapid analysis appearance to carry out the temperature usually, and throwing bullet formula rapid analysis appearance mainly includes detecting head, signal line and analysis appearance, and the detecting head drops into the converter through the mode of throwing the bullet, utilizes the temperature measuring device on the detecting head to carry out the temperature measurement, and the signal passes back the analysis appearance through the signal line that one end and detecting head link to each other, and the analysis appearance is analyzed the signal and is changed into the figure to this lets the staff learn the concrete temperature value in the converter.

Because the temperature in the converter is very high, the detecting head and the signal wire can be melted after 5-10 seconds of putting into the converter, the mass of the detecting head is large, the common signal wire cannot be suitable, and a high-temperature signal wire with good tensile strength and high signal transmission speed needs to be used.

Disclosure of Invention

The applicant provides a high-temperature signal wire for a converter projectile type rapid analyzer aiming at the defects in the prior art, and after the high-temperature signal wire is used, the requirement of tensile strength of a probe after the probe is put into a converter can be met, and the requirement of transmitting a signal back to the analyzer in a short time can also be met.

The technical scheme adopted by the invention is as follows:

a high-temperature signal wire for a converter projectile type rapid analyzer comprises a wire formed by twisting a plurality of conductors together, wherein the diameter of the cross section of each conductor is 0.595-0.605 mm, and the conductor can be a metal wire made of single metal such as copper, aluminum, steel and the like, can also be formed by twisting a plurality of metal wires made of single materials, and can also be a metal wire formed by compounding a plurality of metals; the outer wall of each conductor is respectively fixedly provided with a Teflon layer, the Teflon layer is made of one of FEP (fluorinated ethylene propylene copolymer) or PFA (perfluoroalkyl), the twisting pitch of the wire is 80-120 mm, the twisting pitch refers to the distance of the single conductor advancing along the axis of the wire in a circle of rotation, a rubber layer is fixedly arranged outside the wire, and the diameter of the cross section of the rubber layer is 7.9-9.0 mm.

Furthermore, the conductor is made of steel wires with copper layers wrapped on the peripheries, namely copper-clad steel.

Further, the conductor resistivity of each kilometer of the conductor is less than or equal to 380 omega (ohm), namely, the conductor resistivity of each meter of the conductor is less than or equal to 0.38 omega (ohm).

Further, the thickness of the Teflon layer is 0.195 millimeter (mm) -0.205 millimeter (mm), and further, the Teflon layer is fixedly arranged on the outer wall of each conductor in an extrusion wrapping mode.

Further, the rubber layer is made of CPE (chlorinated polyethylene).

The invention has the following beneficial effects:

the invention has reasonable structure, and the Teflon layer is arranged outside each conductor, so that the conductors can not be melted immediately after being put into the converter, and conditions are created for transmitting signals back to the analyzer; the conductor is made of copper-clad steel, so that high-frequency signals can be rapidly conducted on the surface, and the tensile strength of the conductor is ensured; the twisting pitch design of the invention also gives consideration to tensile strength and signal transmission, if the twisting pitch is too small, the length of the wire is increased, the time for transmitting the signal back to the analyzer is prolonged, and if the twisting pitch is too large, the tensile strength of the invention is reduced.

Therefore, after the invention is used, the requirement of tensile strength of the probe after being put into the converter can be met, and the requirement of transmitting the signal back to the analyzer in a short time can also be met.
