Abstract
The present invention relates to being refined after sea sand ore deposit smelting molten iron, the vanadium titanium elements wherein contained using ore lift the performance of steel.(400MPa grades of above antidetonation building materials of existing market generally add vanadium or niobium, and cost of alloy is expensive) high-strength anti-seismic building materials can be smelted according to different proportionings.Because addition of the sea sand ore deposit containing alloying components such as vanadium 0.3 0.5%, titanium 6 15%, iron 50 60%, the crystal grain of steel is refined instead of conventional a part of manganese element, the intensity, extensibility and corrosion resistance of steel is improved.Existing steel production pattern is broken, has been low cost, high-performance, high-quality upgrading steel product.And preparation technology is easy, conventional smelting iron and steel flow is easily popularized.Part iron ore is substituted using cheap sea sand ore deposit and reduce further production cost, with good economic benefit, social benefit and application prospect.
Description
Technical field
The present invention relates to field of metallurgy, and in particular to purposes of the sea sand ore deposit in production high-strength anti-seismic building materials, Yi Jili
The method that high-strength anti-seismic building materials are produced with sea sand ore deposit.
Background technology
At present, China's iron ore deposit is gradually reduced, and steel production capacity is significantly expanded, and the iron ore deposit of steel production is most of
By import.Sea sand ore deposit contains the valuable metals such as vanadium, titanium, iron, compared with iron ore deposit, and sea sand ore deposit is not only a kind of cheap iron
Source, and the also valuable metal such as vanadium titanium.Iron ore deposit is increasingly reduced at home, steel production increasingly relies on imported iron ore
In the case of, using sea sand ore deposit as a kind of new iron ore deposit, steel production is carried out, significant economic benefit will be brought.
At home, start to be taken seriously as the source of iron of steel-making using pyrometallurgical smelting laterite nickel ore and producing ferronickel in recent years, but
Lateritic nickel ore resource is also limited by Southeast Asian countries.There are the sea sand more than lateritic nickel ore reserves in Indonesia, Philippine Sea water front
Ore deposit, the low-grade and ultralow grade sea sand ore deposit of a large amount of imports is a large amount of using iron content 50%, containing vanadium 0.3%, the cheap sea sand of titanium 6%
Ore deposit (180-220 yuan/ton) will reduce iron ore and a trusted path of cost of alloy, again can be by using wherein vanadium titanium
Composition influence improves the performance of building materials.
The content of the invention
To overcome the application limitation of existing sea sand ore deposit, the invention provides sea sand ore deposit in smelting high-strength antidetonation building materials
Purposes.
The sea sand ore deposit selects iron content 50%-60%, 0.3-0.5% containing vanadium, titanium 6-15%, preferably iron content 55%, containing vanadium
0.5%th, the sea sand ore deposit of titanium 12%.
The invention provides a kind of method that utilization sea sand ore deposit produces high-strength anti-seismic building materials, comprise the following steps：
(1) using sea sand ore deposit with iron ore adapted is sintered, blast furnace process obtains the molten iron containing vanadium, titanium composition；

Step (2) refining can be completed by converter or electric furnace；Composition in fine tuning molten steel can pass through electric furnace
Smelt to complete；
The performance that meets is according to national standard；Or particular/special requirement, produced as a trial through laboratory, check feature reaches specificity
The nickel chromium triangle new material product that can be required；
Step (3) described continuous casting process is existing current conventional production process；
Step (4) described rolling mill practice is existing current common process, is not required to add particular device.
Above-mentioned sea sand ore deposit selects iron content 50%-60%, 0.3-0.5% containing vanadium, titanium 6-15%, preferably iron content 55%, containing vanadium
0.5%th, the sea sand ore deposit of titanium 12%.
Technical scheme regard sea sand ore deposit as a part of source of iron of high-strength anti-shock production of construction materials or whole sources of iron, profit
The high-strength anti-seismic building materials of titanium containing vanadium are obtained with steel-making and steel rolling process.
Fig. 1 is shown in technological process.Detailed step is as follows：
(1) to the composition tracing detection of sea sand ore deposit, result is produced as a trial according to laboratory and formulates rational sea sand ore deposit, iron ore
Proportioning；
Firstth, according to required steel grade national standard requirement, control alloy content is not more than national standard, makes full use of sea sand
Iron in ore deposit；
Secondth, according to laboratory results, by reaching the trial production composition proportion of performance requirement material, formulate suitable
Proportioning and select corresponding sea sand ore deposit kind；
3rd, produce product and possess notable feature and be：Contain vanadium titanium composition in steel product ingredient, (because at present on vanadium
Titanium new material does not have specific national standard, using sea sand ore deposit smelting molten iron, the vanadium titanium member that vanadium Ti content is depended in sea sand ore deposit
Cellulose content and the proportioning with iron ore, but material overall performance after tested, hence it is evident that higher than the material for being not added with vanadium titanium composition), institute
To be referred to as nickel chromium triangle new material；
(2) it is sintered using sea sand ore deposit and iron ore adapted, blast furnace process obtains the molten iron of the composition of titanium containing vanadium；
Sintering, blast furnace are existing common process；
(3) steel-making is entered, refining can be completed by converter or electric furnace；Composition in fine tuning molten steel can pass through electric furnace
Smelt to complete；
When producing national standard steel grade, the vanadium Ti content in molten iron can be strictly controlled by dispensing in allowed band, profit
Can produce molten steel with converter, make full use of the iron in sea sand ore deposit, micro vanadium titanium can be obviously improved steel yield strength,
Tensile strength；
, can be according to performance requirement when producing property and requiring steel grade, laboratory trial production adds that necessary other are micro-
Secondary element, according to the corresponding sea sand ore deposit of laboratory data formulation and iron ore, (particular/special requirement can add other ore deposits after performance is up to standard
Sinter together, example：Need to add nickel chromium triangle in the weather-proof steel bar of 500MPa, 700MPa grades of antidetonations of production, so in sintering deposit matching somebody with somebody
Enter a certain proportion of lateritic nickel ore) proportioning, obtain meeting the composition of performance requirement, by electric furnace refining and finely tune composition and obtain
Preferable nickel chromium.
(4) need to enter continuous casting by kind, casting meets the steel billet of steel rolling process needs；
The continuous casting process is existing current common process, is not required to add particular device；
(5) rolled wire, bar etc..
The building materials bar and wire rod rolling process technique is existing current common process, is not required to add particular device
Technical solutions according to the invention are coordinated with iron ore with sea sand ore deposit or all entered using sea sand ore deposit production sintering deposit
Row is smelted, refining, reduces the cost of manufacture of steel, improves the application of lateritic nickel ore, can be obtained according to different consumptions
To the steel of Multiple Type, and due to the addition of the elements such as vanadium, titanium, the performance of steel, and preparation technology letter are also improved
Just, with good economic benefit and application prospect.
