Description
Technical field
The present invention relates to Steel material technical fields, in particular to a kind of high strength steel material.
Background technology
In recent years, increasing sharply with high-strength structure part and engineering machinery, the worsening of Service Environment, structural steel
Develop towards higher intensity and good low-temperature flexibility direction.In order to reduce production cost, comprehensive performance is improved, is especially solved
The contradiction that intensity improves and welding performance declines, under the premise of ensureing excellent low-temperature flexibility and welding performance, by suitably closing
Reason adjusts conformable metallic content, and the intensity of Steel material can be made to generate very big promotion.
The structure of material determines the performance of material, therefore the intensity of raising steel material and toughness need the tissue from steel
Regulation and control are started with, and corresponding high-performance is obtained by ideal institutional framework.The Strengthening and Toughening approach of traditional metal material is a variety of
It is various, such as working hardening, refined crystalline strengthening, solution strengthening, phase transformation strengthening and the second phase precipitation strength classics Strengthening and Toughening hand
Section.Development of Novel is high-strength or even ultra-high strength and toughness steel are it is necessary to carry out innovative Alloying Design and institutional framework regulation and control,
The mentality of designing for breaking through existing high-strength and high-toughness steel, to realize the great-leap-forward development of high strength and high ductility steel.Presently mainly to carry
The metallurgical quality of high martensite steel and and using control steel inclusion quantity, distribution and form reach improve steel it is tough
Property and intensity, but the cost of steel can be improved.
Therefore a kind of at low cost, toughness height, the high Steel material of intensity are needed at present.
Invention content
To solve the above-mentioned problems, a kind of high strength steel material and preparation method thereof is provided, the present invention uses following technology
Scheme：A kind of high strength steel material, which is characterized in that include the component of following parts by weight：

7 parts, 1-3 parts of manganese, 2-3 parts of molybdenum, 1-2 parts of quartz sand, 4-6 parts of trbasic zinc phosphate, 3-4 parts of phosphoric acid, 3-5 parts of rare earth element, iron 80-90
Part.
First, present invention employs the shared scheme of chromium and phosphorus, the oxidation resistance of steel can be improved, the use of steel is improved
Service life can improve the temperature capacity of steel and can improve the wear resistence of steel in addition present invention employs the scheme of addition molybdenum
And toughness, in addition the present invention also added rare earth element, the compound of appropriate rare earth metal or rare earth metal is added in steel,
Steel can be made to obtain good plasticity, toughness, abrasion resistance, heat resistance, inoxidizability, corrosion resistance.
Preferably, the rare earth element is one or more combinations in scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium.
Preferably, the rare earth element is yttrium and lanthanum, the yttrium and lanthanum ratio are 1: 2-2: 3.
Present invention employs yttriums and lanthanum to be added in steel as rare earth element, due to yttrium and lanthanum have good desulfurization,
Deoxidation, dehydrogenation and the effect for fixing nitrogen can be played the role of improving steel toughness, and coordinate phosphorus that can improve
The intensity of steel.
Preferably, the zirconium is prepared by following methods：
(1) zirconium oxide is mixed with magnesium, 1~3h is heated under the conditions of 1100~1200 DEG C, it is dry after product removal of impurities；
(2) fused salt that step (1) obtains is mixed with sodium chloride, 2~4h is heated under conditions of 1500~1600 DEG C, then
It is washed to neutrality.
The present invention heats 1~3h under the conditions of at 1100~1200 DEG C first, and metallothermic reduction reaction occurs at this time, there is zirconium
It generates, heats 2~4h under conditions of then using 1500~1600 DEG C, nano level zirconium can be formed, help to fill up steel knot
The structural strength of steel is improved in gap on structure, to improve the wearability and toughness of the present invention.
Preferably, the mixed proportion of zirconium oxide and magnesium is 2: 1-4: 1 in step (1), in step (1) and step (2)
Heating process in using nitrogen atmosphere protect.
Present invention employs 2: 1-4: 1 ratio mixed oxidization zirconium and magnesium metal, it is ensured that the reduction rate of zirconium, Er Qieke
To improve the efficiency of reduction, production cost is reduced, in addition uses nitrogen as inert gas shielding, it can be in the follow-up process
The nitrogen fixation of rare earth is coordinated to improve the structural strength of steel.
Preferably, the trbasic zinc phosphate is handled using following methods：Ammonium phosphate and zinc oxide are mixed, then 900
1~2h is reacted at~1200 DEG C, and product is obtained after crushing.
Present invention employs the schemes of ammonium phosphate and zinc oxide hybrid reaction, and trbasic zinc phosphate is generated using high temperature solid state reaction,
This technique is applied in the technology of preparing of steel, this scheme generate trbasic zinc phosphate contained in the crystallization water it is few, therefore for
