Description
Technical field
The present invention relates to metal material deep process technology field, specially a kind of calcium metal bare wire and core-spun yarn linkage production
Technique.
Background technology
Calcium is the A races alkali earth metal of periodic table II, symbol Ca, atomic number 20.Calcium metal is worn by Britain chemist
What dimension was found.
China is one of limestone deposit resource-rich country in the world.In addition to Shanghai, Hong Kong and Macao, in each province, directly
Linchpin city and autonomous region are distributed.Counted according to former State Bureau of Building Materials Industry's geology center, national limestone distribution area is up to 43.8 ten thousand KM2
(not including Tibet and Taiwan), account for the 1/20 of area.
Calcium metal is industrially widely used, particularly since the seventies in last century, with modern science and technology
Continuous development, its application constantly expanding with application field, and international and domestic market increases steadily, and it can be used for
In the industrial production such as metallurgical, chemical industry and electrical equipment, the reducing agent smelted is mainly used as, the desulfurizing agent and decarburizer of ferroalloy, is produced
Reducing agent and production calcium cell and maintenance-free lead, calcium, tin battery and configuration various alloys are done during high pure rare earth metals
Material etc..
In the smelting of excellent special steel, in order to reduce inclusion content of steel, steel product quality is improved, improves pouring for molten steel
Property, in refining process, carry out Calcium treatment has turned into one of conventional technology of smelter.The calcium that generally used in the past,
Be present the shortcomings of low recovery rate and pollution molten steel in iron powder or silicon calcium powder mixing core-spun yarn, had using the pure calcium core-spun yarn of real core following
Advantage：
1st, Calcium treatment process will not bring other oxides existing for pulvis core-spun yarn into and pollute molten steel (such as：In calcium iron wire
Iron oxide and calcium aluminum steel aluminum oxide etc.)；
2nd, plug has a high density and hyperbaric advantage, and plug has minimum specific surface area, can will be due to oxidation
And lose activity, and the calcium oxide field trash that may pollute molten steel is preferably minimized；
3rd, calcium content prolongs calcium line distribution of lengths evenly, and calcium content is higher, more stable, and calcium treatment effect more optimizes；
4th, calcium can be fed to deeper position in molten steel by the highdensity pure calcium pump of real core, and be stopped more below critical depth
The long time, so as to reach the higher calcium rate of recovery；
5th, the highdensity pure calcium pump of real core, quality are easy to detect, and smaller cored wire specific surface area, it is possessed longer guarantor
Deposit the phase.
Depending on steel grade and the rate of recovery calculate.The content basic demand for generally requiring calcium in the steel for carrying out Calcium treatment exists
Between 20-50ppm, the rate of recovery of calcium is calculated by 10-15%, then calcium treated steel per ton needs to use 200-250 grams of calcium metal.
More than the 700000000 tons of steel in the whole nation, steel production capacity, yield do not have development space at present, are only improved quality, improve matter
Amount, increase kind are only the outlet of development, need the Conservative estimation with calcium metal refining according in 3 to five years about 50% steel,
Then the amount for the calcium metal that production high-quality steel in the whole nation needs is：
700000000 tons of ten thousand tons of * 200g/t/1000/1000=14.
Domestic only 20% or so steel is refined with calcium metal at present, needs 5.6 ten thousand tons of calcium metal, effective supply amount
Less than 30,000 tons, market has openings is big, and potential market capacity is big, has good development space.
But existing calcium metal processing technology includes the extruding of calcium metal bare wire and prepared by core-spun yarn, production process is each only
Vertical, the pure calcium silk squeezed out is by twining the processes such as silk, packaging and transport, and corresponding operation post is more so that the production of product
Cost is high, and the fund of waste is more.
And a kind of seamless solid calcium metal for deoxidation in steel making is disclosed in the A of Chinese patent CN 102559997
