Abstract
The invention belongs to field of electrical equipment, disclose a kind of preparation method for electric power line pole tower corrosion-resisting grounding device, it includes, smelt in vaccum sensitive stove；It is molded into steel ingot, then steel ingot is made hollow ingot, then hot trim is carried out to hollow ingot, again scale removal；By the hollow ingot except descale using spraying lubricant.The grounding device corrosion resistance and good of present invention preparation.
Description
Technical field
The invention belongs to field of electrical equipment is and in particular to a kind of preparation method for electric power line pole tower corrosion-resisting grounding device.
Background technology
At present, the grounding device that China's electric power line pole tower is commonly used is galvanized steel, copper plated steel (copper covers steel) or copper material grounding device, and practical application shows, galvanized steel grounding device corrodes more serious in acid ground；Copper plated steel (copper covers steel) or copper material grounding device construction costs are high, and environmental pollution is serious, and the polarization corrosion between two kinds of different metals can be occurred to react when its electroplating surface layer damages, and accelerate the corrosion of grounding device；Therefore, at present due to lacking special material and related technology, not yet there is a kind of acid ground that is not only suitable for be applied to electric power line pole tower corrosion-resisting grounding device of basic soil, Life cycle low cost, resources conservation, environmental friendliness shape and preparation method thereof again.
Content of the invention
It is an object of the invention to provide a kind of preparation method for electric power line pole tower corrosion-resisting grounding device, the grounding device mechanical strength of the method preparation is big, good corrosion resistance.
The concrete scheme of the present invention is：
A kind of preparation method for electric power line pole tower corrosion-resisting grounding device, it comprises the steps：
(1) Al 0.001%, La 0.001%, Nd 0.002% are taken according to percentage by weight, C 0.002%, Si 0.15%, Mn 0.3%, Ni 2.0%, Cr 16%, Mo 1.5%, N 0.02%, W 0.2%, O 0.005%, S 0.005%, P 0.02%, balance of ferrum, smelt in vaccum sensitive stove；
(2) it is molded into steel ingot first, then steel ingot is made hollow ingot, then hot trim is carried out to hollow ingot, again scale removal；
(3) by the hollow ingot except descale using spraying lubricant, coating thickness：0.4mm, wherein lubricant are by magnesium oxide, silicon dioxide and zirconium oxide according to 1：1：1 mass ratio mixes；
(4) hollow ingot is extruded into by pipe using extruder；It is eventually fabricated the steel pipe of given size, obtain final product.
Specific embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, below in conjunction with the application specific embodiment, the present invention is more clearly and completely described it is clear that, described embodiment is only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, all should belong to the scope of protection of the invention.
Embodiment 1
A kind of preparation method for electric power line pole tower corrosion-resisting grounding device, it comprises the steps：
(1) Al 0.001%, La 0.001%, Nd 0.002% are taken according to percentage by weight, C 0.002%, Si 0.15%, Mn 0.3%, Ni 2.0%, Cr 16%, Mo 1.5%, N 0.02%, W 0.2%, O 0.005%, S 0.005%, P 0.02%, balance of ferrum, smelt in vaccum sensitive stove；
(2) it is molded into steel ingot first, then steel ingot is made hollow ingot, then hot trim is carried out to hollow ingot, again scale removal；
(3) by the hollow ingot except descale using spraying lubricant, coating thickness：0.4mm, wherein lubricant are by magnesium oxide, silicon dioxide and zirconium oxide according to 1：1：1 mass ratio mixes；
(4) hollow ingot is extruded into by pipe using extruder；It is eventually fabricated the steel pipe of given size, obtain final product.
Corrosion testing is the experimental liquid in being held in autoclave：25% NaCl aqueous solution (liquid temperature：230 DEG C, the CO under 50 atmospheric pressure2Gas atmosphere) in, immersion corrosion sample, is 4 weeks during immersion.For the sample after corrosion testing, measure its weight, according to the decrement of the sample weight before and after corrosion testing, being computed corrosion rate is 0.15mm/y.In addition, with regard to resistance to spot corrosion, steel pipe is soaked in 50% CaCl2(liquid temperature：100 DEG C) in solution, to soak 2 days, research has or not the generation of spot corrosion.Observing that the spot corrosion in more than 0.1mm for the diameter has been defined as spot corrosion, situation in addition is defined as no spot corrosion, it is observed that corrosion-free point occurs.
Above in association with specific embodiment, invention has been described, it will be appreciated by those skilled in the art that these descriptions are all exemplary, is not limiting the scope of the invention.Those skilled in the art can make various variants and modifications according to spirit and principles of the present invention to the present invention, and these variants and modifications are also within the scope of the invention.
