Abstract
The present invention relates to a refractory alloy composition which belongs to a smelting technique and contains 0.02 to 0.8% of C, 0.2 to 0.5% of Mn, 3 to 15% of Cr, 0.5 to 3 % of Si, 0.2 to 3.5 % of Al, 0.01 to 0.5 % of Mo, 0.001 to 0.006 % of B, 0.01 to 1.5 % of additive and Fe as the rest. Under the condition of keeping the combination property of the alloy unchanged, the alloy cost is greatly reduced.
Description
Technical field
The present invention relates to smelting technology, is a kind of refractory alloy composition.
Background technology
Existing heat-resisting allay material, some alloy adding is higher, and for example: the add-on of chromium is generally about 30% usually.This just causes smelting cycle lengthening, complex process, and deficiencies such as cost up in addition, must add nickel (Ni) in traditional refractory alloy component, and the costing an arm and a leg of nickel, institute is so that cost of alloy is higher.
Summary of the invention
The purpose of this invention is to provide a kind of refractory alloy composition, make it keep reducing cost of alloy significantly under the constant prerequisite of alloy over-all properties.
The present invention for the technical scheme of finishing the foregoing invention purpose and providing is, a kind of refractory alloy composition, its component and content are: 0.02-0.15% carbon, 0.2-1.5% manganese, 6-8% chromium, 0.5-3% silicon, 0.2-3.5% aluminium, the 0.01-0.5% molybdenum, 0.001-0.006% boron, the niobium of 0.01-1.5%, titanium additives and balance iron.Described additive generally is the combination of at least two kinds of materials in niobium, titanium, the vanadium.Described a kind of refractory alloy composition, its component and content are: 0.15% carbon, 0.45% manganese, 7% chromium, 2.5% silicon, 1% aluminium, 0.02% molybdenum, 0.002% boron, 0.05% niobium, titanium and balance iron.Content in the each component of the present invention all by weight percentage.
Alloy of the present invention proves to have good comprehensive performances through commerical test, and has good welding property, high tenacity, good anti-Quench, sharp thermal characteristics etc., and technology is simple, cost of alloy reduces significantly.
Contribution of the present invention is, the content of alloying element is significantly reduced than prior art,, utilize its interaction to replace nickel element simultaneously with element combinations such as chromium, aluminium, silicon, manganese, and obtain performances such as high temperature resistant, that oxidation-resistance is strong equally, cost is reduced significantly.The present invention adds chromium, aluminium, element silicon in iron after, can improve the appearance temperature of ferric oxide.When containing these elements in the steel, interaction can take place between them, form alloy oxide film, as: Cr
2O
3, Al
2O
3, FeO-Cr
2O
3, FeO-Al
2O
3, Fe
2SrO
4Deng, these alloy oxide films have good protective action.Alloy of the present invention step manufacturing as follows: 1, the blast-melted processing rear converter that gives adds waste materials such as steel scrap, fluorite, ore when inferior.2, carry out deoxidation alloying; 3, molten steel furnace external refining; 4, continuous casting or ingot casting, foundry goods, foundry goods is 900-1200 ℃ of normalizing treatment; 5, controlled rolling, cooling.Metallographic structure of the present invention is based on ferrite and a small amount of troostite or bainite.Evidence, solderability is good, does not undergo phase transition, and profile does not change under Quench, sharp enthusiasm condition.
