Abstract
A kind of high strength cored line, including steel band clad and core body；The both sides of steel band clad are axially suppressed with several grooves along core body.Compared with prior art, the beneficial effects of the utility model are：A kind of high strength cored line, increase a number of groove on core-spun yarn circumference and substantially increase cored line strength, due to producing the secondary compaction to core material simultaneously, further increase cored line strength, the plum blossom tee section formed is compared with typical round section, during same cross-sectional diameter, effective area reduces, and reduces underthrust resistance, make to penetrate slag ability and be remarkably reinforced, core-spun yarn insertion depth is added, reduces melting loss of elements, improves utilization rate.This programme is fully utilized original core cabling wire machine and makes cored wire material, need not transform and invest substantially.
Description
Technical field
It the utility model is related to metallurgical furnace outer refining technology field, more particularly to a kind of high strength cored line of steel-making.
Background technology
External refining processing is carried out to molten steel in the form of core-spun yarn, is a kind of skill for starting late 1970s to occur
Art.Have become modern steel at present and produce indispensable important step and means.It is micro- to deoxygenation of liquid steel, desulfurization, composition
To adjust, improve nonmetal inclusion form, promote inclusion floating, cleaning molten steel and other effects notable, there is small investment, technique is simple,
The features such as efficiency high.
Traditional core-spun yarn is usually to be made up of steel band clad and core material.Wherein clad is 0.3-0.5mm by thickness
Steel band make, core material is made up of the powdery of metal and alloy, filamentary material and its compound material, and clad and core material are in cored
By molding roller compacting parcel shaping on line machine, then carry out the processes such as fold seals seaming, consolidation, finishing and be rolled into a tool
There is the core-spun yarn of certain length.Because external coating is relatively thin, therefore cored line strength is relatively low, the saturating slag energy during molten steel is fed
Power is poor, and core-spun yarn, which is easily bent, is coiled in ladle top, and some is even swum on slag surface, it is impossible to preferably inserts ladle
Bottom, cause melting loss of elements serious, not only pollute environment, also add the dosage of core-spun yarn simultaneously, increase steel-making cost.
There is presently no very good solution.Attempt to improve this situation using the method for increase coating thickness, but
Larger problem be present, be primarily due to the increase of clad thickness of strips, the difficulty increase that core-spun yarn makes, even with existing
Qualified product can not be made in some core cabling wire machines.
Utility model content
The purpose of this utility model is to provide a kind of high strength cored line, increases the intensity of core-spun yarn, reduces core-spun yarn
Net sectional area, underthrust resistance is reduced, enhancing core-spun yarn penetrates the ability of slag, so as to increase the insertion depth of core-spun yarn.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of high strength cored line, including steel band clad and core body；Axially suppressed along core body the both sides of steel band clad
There are several grooves.
The thickness of the steel band clad is 0.3mm-0.5mm.
The groove is diameter 2mm-3mm semicircle.
The groove is collar extension width L=2mm-3mm, and depth is the trapezoidal of 2mm-3mm.
The groove is collar extension width D=2mm-3mm, and depth is 2mm-3mm V-arrangement.
Compared with prior art, the beneficial effects of the utility model are：
A kind of high strength cored line, increasing a number of groove on core-spun yarn circumference, to substantially increase core-spun yarn strong
Degree, due to producing the secondary compaction to core material simultaneously, cored line strength is further increased, the plum blossom tee section formed
Compared with typical round section during same cross-sectional diameter, effective area reduces, and reduces underthrust resistance, makes to penetrate slag ability obvious
Enhancing, adds core-spun yarn insertion depth, reduces melting loss of elements, improve utilization rate.Original cored is fully utilized in this programme
Line machine and making cored wire material, need not transform and invest substantially.

Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of high strength cored line, including steel band clad 1 and core body 2；Axially pressed along core body the both sides of steel band clad 1
It is formed with several grooves 3.The quantity of groove is 4-6.Core material is by metal and the powdery or filamentary material of alloy, or powdery and silk
Shape compound material forms.
The thickness of the steel band clad 1 is 0.3mm-0.5mm.Using SPCC steel bands.
Embodiment 1：
As shown in figure 1, a kind of high strength cored line, including steel band clad 1 and core body 2；The both sides edge of steel band clad 1
Core body is axially suppressed with 4 grooves 3.
The groove 3 is diameter 2mm-3mm semicircle.
Embodiment 2：
As shown in Fig. 2 a kind of high strength cored line, including steel band clad 1 and core body 2；The both sides edge of steel band clad 1
Core body is axially suppressed with 6 grooves 3.
The groove 3 is collar extension width L=2mm-3mm, and depth is the trapezoidal of 2mm-3mm.
Embodiment 3：
As shown in figure 3, a kind of high strength cored line, including steel band clad 1 and core body 2；The both sides edge of steel band clad 1
Core body is axially suppressed with 6 grooves 3.
The groove 3 is collar extension width D=2mm-3mm, and depth is 2mm-3mm V-arrangement.
A kind of high strength cored line of the utility model, including the SPCC steel bands clad 1 and core body that thickness is 0.3-0.5mm
2.A diameter of 10-16.8mm of finished product core-spun yarn；Core-spun yarn is made by core cabling wire machine flanging, curved arc, sealing, compacting.Make
Be provided with during high strength cored line, in compacting process in the groove of last group of two pairs of rollers of core cabling wire machine several fins (it is semicircle,
Trapezoidal or V-arrangement), core-spun yarn section is pressed into plum blossom-shaped using fin, this not only dramatically increases clad intensity, while to core material
Further compacting also functions to the effect of increase cored line strength, and plum-blossom-shaped section is made by former pure circle tee section in core-spun yarn in addition,
Reduced cross-sectional area.Line feeding resistance can be reduced to a certain extent, and these factors add core-spun yarn insertion molten steel depth, make useful member
Plain absorptivity improves about 15~20%.The utility model reduces the dosage of core-spun yarn, reduce manufacturer ton steel-making into
This, and it is simple and easy without the investment and production cost, the program of increase production producer.
