Abstract
The utility model discloses a high strength contains calcium core -spun yarn, include and contain calcium inner core, steel strand wires and surrounding layer, its characterized in that contain the calcium inner core with the steel strand wires quilt the surrounding layer cladding, the interior cross -section of steel strand wires be cellular texture, it has increased steel strand wires between the calcium inner core mainly to embody at the surrounding layer and contain, has reached the purpose that improves core -spun yarn intensity, can realize with the core -spun yarn with great speed feeding to the molten steel in, weakened the gasification phenomenon of calcium metal to improved the receipts yield of calcium metal, and the splash problem can effectively solve molten steel calcium and handle the time.
Description
Technical field
The utility model is related to make steel furnace outer refining technology, is related to a kind of molten steel Calcium treatment high intensity containing calcium core-spun yarn.
Background technology
Calcium treatment is a kind of liquid steel refining means that 20 century 70s grow up.Its main purpose includes：(1) depth
Reduce the harmful element content such as [O], [S] in steel；(2) field trash composition form is changed, it is to avoid casting aluminum killed steel occurs the mouth of a river
Block and improve steel mechanics performance.
But due to the fusing point of calcium metal low (845 DEG C), low boiling point (1450 DEG C), slag surface is easily floated in molten steel
It is upper with air in oxygen and the oxide in slag liquid react and scaling loss is fallen, while cause fairly large molten steel, slag splash, shadow
Ring execute-in-place.So as far as possible core-spun yarn is fed into into molten metal deep when feeding silk, using the static pressure of molten metal, calcium metal is prevented
Quick-gasifying, so as to extend calcium metal time of staying in molten steel, good Calcium treatment effect is played to molten steel.Want cored
Line is fed into molten steel to be goed deep into, and wherein one of method increases the feeding speed of core-spun yarn so that core-spun yarn is with a larger speed
Degree is rapidly introduced into molten steel to be goed deep into, but general core-spun yarn is only to be wrapped in outside inner core with surrounding layer iron sheet, and tension is strong
Degree is general, when higher feeding speed is through feeding wire machine, is easily pulled off, and causes line feeding to be interrupted, and affects line feeding effect.
" seamless calcium iron wire " utility model patent that China Intellectual Property Office's on January 2nd, 2013 authorizes, it is intended that with increase
Outer layer thickness increases come the depth for making core-spun yarn feeding molten steel, the use of the seamless box hats of 0.8～1.2mm is that Jing high-frequency weldings are formed,
Wish the intensity for increasing core-spun yarn with this, core-spun yarn is fed into into molten steel depths, but the single line intensity of this core-spun yarn is too high,
Pliability is poor, is not suitable for existing feeding wire machine and uses, and directly results in the phenomenon for occurring core-spun yarn skidding when molten steel is fed, shadow
The recovery rate of calcium metal is rung, is unfavorable for accurately feeding calcium.And its difficulty of processing is big, high cost.
Utility model content
The purpose of this utility model is that, according to above-mentioned the deficiencies in the prior art part, the utility model purpose is realized a kind of high
Intensity contains calcium core-spun yarn, including calcic inner core, steel strand wires and surrounding layer, it is characterised in that described calcic inner core and described
Steel strand wires are coated by described surrounding layer, and the inner section of described steel strand wires is in alveolate texture.
The thickness of surrounding layer described further is 0.3～1.0mm.
A diameter of 0.5～the 2.0mm of steel strand wires described further.
Surrounding layer described further in the way of hasp or welding in one kind be coated on calcic inner core and steel strand wires it
Outward
Calcic inner core described further is the metallic calcium powder that calcium content is 85%-100%.
A diameter of 10～the 16mm of high intensity described further containing calcium core-spun yarn.
Of the present utility model having the technical effect that increased a steel strand wires between surrounding layer and calcic inner core,
The purpose for improving cored line strength is reached, has been capable of achieving core-spun yarn to be fed in molten steel with larger speed, reduced metal
The gasification phenomenon of calcium, so as to improve the recovery rate of calcium metal, and expulsion problem when can effectively solve the problem that molten steel Calcium treatment.
Description of the drawings
Fig. 1 is the sectional view of first embodiment hasp of the present utility model.
Fig. 2 is the sectional view of second embodiment welding of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than the reality of whole
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment for obtaining, belongs to the scope of the utility model protection.
Contain calcium core-spun yarn with reference to a kind of high intensity in the utility model that accompanying drawing 1, accompanying drawing 2 are further illustrated, including containing
Calcium inner core 2, steel strand wires 3 and surrounding layer 1, it is characterised in that calcic inner core 2 and steel strand wires 3 are coated by described surrounding layer 1, steel
The inner section of twisted wire 3 is in alveolate texture, and such structure ensure that intensity of the high intensity containing calcium core-spun yarn.
Wherein, the thickness of surrounding layer 1 is 0.3～1.0mm；A diameter of 0.5～the 2.0mm of steel strand wires 3；Surrounding layer 1 it is general with
The form (such as accompanying drawing 1) of hasp is fixed, it would however also be possible to employ calcic inner core 2 of the mode (such as accompanying drawing 2) of welding by
Steel strand wires 3 are coated on surrounding layer 1；Mainly used suitable for the higher occasion of rigidity in the form of hasp, using welding
If form, the line feeding being mainly used in feeding wire machine, during line feeding, the smooth degree of the surrounding layer 1 of welding is higher,
Easily line feeding, above-mentioned calcic inner core 2 is the metallic calcium powder for 85%-100% for calcium content；The institute in the utility model
