Description
Technical field
The present invention relates to field of alloy material, refer in particular to a kind of high alloy steel pipe perforating heading material and surface treatment method thereof.
Background technology
In the forming process of weldless steel tube, perforating head is the most important thing of mold tool, and the pyritous steel billet is in perforation procedure, and perforating head will bear the effect of each side power such as self compaction, hurried self dilatational strain.Working conditions is extremely abominable, particularly when piercing high alloy steel pipe, himself has fine toughness, and perforating head generally can only select for use traditional price, expensive full molybdenum plug to pierce.Those skilled in the art know that all full molybdenum plug is high temperature resistant, and the top self need not to cool off and can also pierce continuously in perforation procedure.This type of high quality steel of boring a hole
,At high temperature the surface can not touch water; Not so can produce great hidden danger to the quality product of pipe, form because full molybdenum plug material is a powder metallurgy, the material structure system looses; Hardness is extremely low; The surface, top is easy to wearing and tearing in piercing steel pipe, and the top cycle in work-ing life is short, and comprehensive price ratio is very low; Piercing this type of steel if adopt the higher tungsten nickel molybdenum oxidation of alloy to come directly towards, is to reduce the perforation cost effectively.But this type of top needs inner chamber to use water cooling, otherwise can only prop up through 1-2, and the nose chamber of collapsing can appear in the top, the steel bonding of roll off band, and phenomenon such as lose flesh is serious, thereby causes blank tube material to scrap.Chinese patent ZL200910000886.9 discloses a kind of new material of hot perforation top head of steel pipe, because it has increased the content of MO and W element in material, has added an amount of AL and REE CE simultaneously; Intensity, wear resisting property, hardness, plasticity and the thermostability of material have been improved; Effectively overcome the shortcoming of prior art, reduced cost, but because the kind of material is complicated; The difficult control of content during making; Required element neither usual handy element, and cost of manufacture is higher, haves much room for improvement.
Summary of the invention
The present invention provides a kind of cost moderate just in order to overcome above-mentioned deficiency, long service life, the high alloy steel pipe perforating heading material that cost performance is high.The material that main innovation is to change the top is that iron-based contains top materials such as Co, Nb, V, S, P; It specifically is to implement like this: a kind of high alloy steel pipe perforating heading material; The composition (weight %) that it is characterized in that this material by: C:0.16-0.4% Si:0.6-1.2% Mn:0.4-1.2% Cr:0.5-2% Ni:2-5% Mo:0.6-1.6% W:0.5-2.5% Co:0.8-1.2% Nb:0.3-0.6% V:0.3-0.6% S≤0.01% P≤0.01%, surplus is iron and inevitable trace impurity.
Introduce the effect of each alloying element in high alloy steel pipe perforating heading material of the present invention below respectively:
1.C content (below the weight percent all with) 0.16-0.4, C is a carbide forming element, and an amount of carbon can improve firm hardness; But the existence of excessive carbon has reduced the toughness of steel, is unfavorable for oxidation and nitriding treatment; It is unfavorable that abominable operating mode is used, and is unfavorable for forming compact oxide.
2.Si content 0.6-1.2 adds the cementability that an amount of Si can improve zone of oxidation and matrix, improves the high-temperature resistant tempered performance of alloy, this is to being absolutely necessary the work-ing life of improving the top.
3.Mn content 0.4-1.2 adds an amount of Mn, has improved the hot strength of perforating heading material greatly.
4.Cr content 0.5-2 can promote the formation of carbide equally, improves the hot strength of material, but too much is prone to cause the cost of material to improve.
5.Ni content 2-5, the hot strength of raising material.
6.Mo content 0.6-1.6, the heat resistance ability of raising material, wear resisting property and stability improve work-ing life.
7.W content 0.5-2.5 promotes carbide to form, and improves the hardness of material through solution strengthening.
8.Co content 0.8-1.2, as reductor and degasifier, in material, cause intracrystalline strengthen obviously can fine and close steel alloy tissue, crystal grain thinning, maintenance intensity, obviously improve intensity and toughness, enhancing creep resistance, increase wear resistance.
9.Ne content 0.3-0.6, as when steel-making good reductor and degasifier, in material, cause intracrystalline strengthen obviously can fine and close steel alloy tissue, crystal grain thinning, maintenance intensity, obviously improve intensity and toughness, enhancing creep resistance, increase wear resistance.
10.V content 0.3 adds and in material, improves intensity and toughness in right amount, as reductor.
11.S content≤0.01 adds an amount of element and improves high-temperature oxidation resistance and scale resistance and erosion resistance.
12.P content≤0.01 adds an amount of element and improves high-temperature oxidation resistance and scale resistance and erosion resistance.
The present invention is through adding element materials such as proper C o, Nb, V, S, P in iron-based; Make this type of ferrous alloy have enough hot strengths; Alloying element W, Co, Mo, Cr, Nb, V cause the intracrystalline reinforcement obviously in material, thereby have improved steel alloy use properties at high temperature greatly, thereby matrix is at 800 ℃ and to the Working environment more than 1000 ℃; Need not cool off water inside, fracture and other breakoff phenomenons generally can not take place yet.
The method of manufacture of this heading material is: above-mentioned element is proportionally put into the intermediate frequency furnace fusing; Holding temperature is 1600-1750 ℃; The molten steel tapping temperature is 1460-1550 ℃, and through the blank of common sand mold casting casting top, cooling is after Full Annealing then; Annealing temperature is 870-890 ℃, after the machine tooling moulding.
