3oxide film, this oxide film has higher compactness and passivation, can play good isolated and provide protection, make steel have high oxidation-resistance to the oxidation of inner layer metal; In addition, Cr also forms the intensity that carbide improves steel, but excessive chromium makes the thermoplasticity of steel worsen, and tissue is unstable, and consider, its total content controls 16 ~ 18%.
Si to improving the hardening capacity of steel, temper resistance, toughness, especially elastic limit are favourable, reduce γ phase block elements, do not form carbide, along with the increase of silicone content, the precipitation of carbide is suppressed or delay, but excessive Si easily causes cold short, and welding property is poor, therefore the content of Si controls 5 ~ 6%.
Mn adds the hot strength being conducive to improving high temperature steel, and expand γ phase region, forming unlimited solid solution, is weak carbide forming element, enters cementite and replaces part iron atom, form alloyed cementite.The content of manganese too much easily causes grain coarsening and increases temper brittleness, the thermal conductivity of metal can be made to reduce, can promote that σ phase generates simultaneously, alloy is become fragile when being heated for a long time, in austenite, add Mn be mainly used for replacing Ni, consider, the content of Mn controls 2.5 ~ 3.5%.
Mo can improve the intensity of steel, forms carbide, can realize dispersion-strengthened with austenite solid solution, the isothermal curve of steel is moved to right, strengthen the resistance for delayed fracture of steel, molybdenum can suppress the impurity atomss such as P, Sn to the segregation of grain boundaries, therefore can reduce temper brittleness; Can improve the hardening capacity of steel, the content of molybdenum is too low, DeGrain, and content is too high, then cost is higher, considers, and controls at Mo 1 ~ 2% containing molybdenum amount.
Ni has very high resistance of oxidation, is to be formed and the principal element of stable austenite, and Ni acts on about 10% time maximum on the impact of hot strength, and Ni too much in steel is mainly used to balance and reduces γ phase region alloys producing; The control of General N i content must obey the requirement forming single austenite structure, but Ni is expensive, and in order to reduce costs and price, part C and N can be utilized to replace Ni, and play the effect of stable austenite, consider, the content of Ni controls 9 ~ 11%.
Al and Ti adds, and is in order to the Ni with Ni production Dispersed precipitate
a(Al, Ti) phase, i.e. γ
,phase, this is typical ageing strengthening phase, due to γ
,the effect of phase, thus ensure that steel at high temperature has higher hardness and intensity.Meanwhile, add the Al of 3 ~ 5% in the present invention and the Ti of 1 ~ 1.5% matches with 0.1 ~ 0.3%Ce, not only can form foregoing γ
,phase, all right crystal grain thinning and stabilizing tissue, meanwhile, Al element can also form fine and close Al
2o
3oxide film, at the stable firmly anti-oxidant and kinds of anti-sulfur corrosion protective layer of the Surface Creation of material matrix.
V can form carbon vanadium compounds disperse educt minutely, thus improves the creep strength of material; Its content is inoperative very little, can produce brittle tendency too much.Consider, the content of V controls 0.1 ~ 0.2%.
Cu is to form rich copper precipitated phase in high temperature creep process, thus improves the high temperature creep strength of material.In order to reach this effect, its content must be greater than 0.1%, but copper content is too high can damage its processing characteristics, considers, and controls 0.5 ~ 1% containing Cu amount.
Adding of rare earth element ce, the as-cast structure of steel, cleaning molten steel can be improved, in the molten steel of high temperature, Rare-Earth Ce easily with oxygen and sulphur generation conjugation reaction, give birth to glomerate Ce
2o
2s, Ce

3deng cerium oxysulfide, thus the oxygen removed in molten steel and sulphur.Therefore, cerium has stronger deoxidization desulfuration ability; Because cerium is surface active element, non-spontaneous nucleating center can be formed, thus crystal grain thinning, improve plasticity and the toughness of steel, consider, control at 0.1-0.3% containing cerium amount.
S is the harmful element in steel, and S can only be dissolved in the molten steel of high temperature, almost can not dissolve in solid iron, the grain boundaries in solid steel is present in the form of FeS inclusion, easily causing cracking during hot-work, be called hot-short, its content should be strict controlled in≤level of 0.03%.
P has solution strengthening effect, can improve intensity and the hardness of steel, but sharply can reduce the impelling strength of steel, and phosphorus can gather at grain boundaries, forms serious segregation, causes temper brittleness, and its content is strict controlled in≤level of 0.03%.
The present invention can adopt the method for electric arc furnace+external refining or non-vacuum induction furnace+external refining to smelt, ferrochrome, molybdenum-iron, ferromanganese, ferrosilicon and aluminum shot is added successively in smelting process, when smelting is near completion, add vanadium iron, ferrotianium, pure nickel, fine copper and rare-earth element cerium successively, at utmost can reduce the element consume of pyroprocess like this, tapping temperature controls at 1580 ~ 1600 DEG C.Because containing higher C and Si two kinds of elements in high temperature steel of the present invention, these two kinds of elements ensure that good castability.Common sand mold casting can be adopted, direct pouring becomes charging frame, drop-bottom, grating plate part of all kinds, also can be cast into steel ingot, then forge as required, be rolled into various distortion materials etc., also can be cast into foundry goods, directly use in the as-cast condition.
