The invention relates to super-strength sucker rod steel which is characterized by comprising the following chemical components in percentage by weight: 0.23-0.46 percent of carbon (C), 0.1-0.3 percent of silicon (Si), 1.25-1.55 percent of manganese (Mn), less than 0.02 percent of phosphorus (P), less than 0.015 percent of sulphur (S), 0.05-0.15 percent of vanadium (V), 0.025-0.032 percent of chromium (Cr), 0.05-0.13 percent of rare earth (Re) and the balance of iron (Fe), wherein the rare earth is a mixture of lanthanum (La) and cerium (Ce). The invention has the advantages of high comprehensive mechanical property, overall consistent corrosion resistance, super strength and anti-corrosion, breaks the limits of technical means of shot blasting strengthening or electroplating chemical treatment, and the like to the strengthening or the anti-corrosion of the sucker rod and is a brand-new low-cost sucker rod material.
Description
Technical field
The present invention relates to a kind of super-strength sucker rod steel, belong to the alloy steel material field.
Background technology
According to SY/T5029 " sucker rod " standard, conventional sucker rod is divided into by its mechanical property: K, C, D Three Estate, supporting capacity exceeds the D level, be that minimum stress is at 0-102Mpa, the sucker rod that the permissible stress value exceeds D level 35% mechanical property is the sucker rod of superstrength, and super-strength sucker rod is divided into again: material-type (code name HL) and two types of sucker rods of craft type (code name HY).Its regular size, promptly body of rod diameter is: four kinds of 5/8in (Φ 15.9), 3/4in (Φ 19.1), 7/8in (Φ 22.2) and 1in (Φ 25.4).
HY type sucker rod is selected to meet the YB/T054 standard except starting material, also must carry out surface strengthening and coating and handle, and be prone to surface imperfection, belongs to the craft type super-strength sucker rod.
HL type sucker rod is brought up to the superstrength grade by selecting suitable material (meeting the YB/T054 standard) for use with mechanical property, as material: 30CrMoA, belong to typical case's representative of material-type (HL type) super-strength sucker rod type, though its mechanical property conformance with standard requirement.But alloying element prices such as Mo wherein, W, Cr are all higher, cause the product prices of raw and semifnished materials more expensive.
But two kinds of superstrength HY types and HL type sucker rod are rich in H running into oil well well liquid
2During corrosive mediums such as S, being easy to generate fatigue corrosion fracture lost efficacy, moreover each oil field oil recovery operating mode difference is bigger, be rich in various different corrosive mediums in the well liquid, make the sucker rod extent of corrosion that very big difference be arranged again, as: the well liquid in oil fields such as triumph, Central Plains, Xinjiang all contains a large amount of corrosive mediums, cause sucker rod shortening working life, and the oil well that deep-well, ultra deep well and big pump are adopted by force increases gradually, and the oil field presses for superstrength and corrosion resistance nature sucker rod stronger, that dual performance has both occurs.
HL type super-strength sucker rod relies on material itself to reach mechanical property requirements, but anticorrosion cracking performance is not good enough.HY type super-strength sucker rod reaches mechanical property requirements by means of surface strengthening or thermal treatment means, but after the surperficial coated layer generation spot corrosion, corrosion phenomenon increases the weight of rapidly, and corrosion resistance nature is also imperfect.
Summary of the invention
The purpose of this invention is to provide a kind of comprehensive mechanical performance height, the whole unanimity of corrosion resistance nature, and the stronger super-strength sucker rod steel of corrosion resistance.
In order to realize purpose of the present invention, the technical measures that adopt are: with D level pole stock matter is that the material of 25MnV is a parent chemical ingredients prescription, add suitable rare earth, chamber prescription and mechanical property and antiseptic property experimental result by experiment, adjust the dispensing ratio of each element of material, finally develop a kind of not only superstrength but also the novel material of sucker rod of acid-and base-resisting corrosive.
The chemical ingredients of super-strength sucker rod steel of the present invention is by weight percentage: carbon (C): 0.23-0.46%, silicon (Si): 0.1-0.3%, manganese (Mn): 1.25-1.55%, phosphorus (P): sulphur (S)＜0.02%:＜0.015%, vanadium (V): 0.05-0.15%, chromium (Cr): 0.025-0.032%, rare earth (Re): 0.05-0.13%, surplus is an iron, and wherein: rare earth is the mixture of element lanthanum (La) and cerium (Ce).
Advantage of the present invention is: comprehensive mechanical performance height, the whole unanimity of corrosion resistance nature, superstrength and anticorrosion having concurrently; Having broken through sucker rod is strengthened or the restriction of technique means such as anticorrosion employing shot peening strengthening or electroplating chemical processing, is a kind of completely newly material of sucker rod cheaply.
Embodiment
Embodiment: with D level pole stock matter is that the material of 25MnV is a parent chemical ingredients prescription, adds suitable rare earth.
(1) production technique:
Feed Si-Ca line-continuous small-billet casting-steel billet heating-bar continuous rolling-scale-inspection-packing warehouse-in after hot metal pretreatment-converter smelting-aluminium manganese silicon deoxidation-LF refining feeding rare-earth wires-refining in early stage.
(2) production smelting operation:
In the converter tapping process, adopt the Cr iron alloyization; The deoxidation of aluminium manganese silicon, LF refining feeding rare-earth wires in early stage is fed the Si-Ca line after the refining, and refining finishes to keep the soft blow of certain hour; Ladle direct casting platform is cast, specification 150mm * 150mm.
Because steel of the present invention are to be that the material of 25MnV is a parent chemical ingredients prescription with D level pole stock matter, add suitable rare earth and make, so called after: 25MnVRe.
The production testing data of 25MnVRe steel are as follows:
