Abstract
The utility model discloses an inactive metal magnesium base core-spun wire, which is suitable for the technical field of molten iron and molten steel desulfurization. The inactive metal magnesium base core-spun wire comprises a wrapper and a core part. The utility model is characterized in that the outer diameter of the inactive metal magnesium base core-spun wire is 6-20MM; the thickness of the wrapper is 0.2-1.5MM; the materials of the core part are inactive metal magnesium materials with the particle size of 0.2 to 1.2MM. Using the inactive metal magnesium base core-spun wire of the utility model has the advantages of low cost, high hit ratio, little molten iron and molten steel temperature drop, high safety, less pollution, less investment, convenient operation, low labor intensity, etc.
Description
The utility model belongs to molten iron, molten steel desulfurizing technical field, particularly relates to a kind of passive metal magnesium base cored wire technology.
Molten iron, molten steel desulfurizing generally adopt pulvis blowing process or paddling process desulfurization technology in the existing technology, although these several desulfurization technologies can be sloughed the sulphur in molten iron or the molten steel preferably, but exist the desulfurization hit rate low, splash is big, seriously polluted, temperature drop is big, dangerous and blowing device is huge, investment cost height of equipment, the control manipulation difficulty, expensive many, consume problems such as height.
More domestic steel mills have begun with powder mixtures such as passive metal magnesium and calcium oxide, fluorites as magnesia composite desulfurizing agent.And adopt the blowing process or the paddling process separation of flow, obtain certain effect, but can not solve the disadvantage that powder desulfurization brings.And with the cost of passive metal magnesium base compound powder desulphurization cost greater than common CaO, CaC sweetening agent, and these methods still do not break away from traditional winding-up, stir the pulvis sulfur removal technology.
The purpose of this utility model is the problem that exists in the existing technology, proposes a kind of pure passive metal magnesium cored-wire or passive metal magnesium base composite core-spun yarn.Be applied in molten iron, the molten steel desulfurizing operation, not only can improve hit rate, reduce cost, reduce and pollute, make the equipment scalp low, safe and reliable, and minimizing personnel preparation, labour intensity reduced.
The purpose of this utility model is to realize by technical scheme as described below.
Passive metal magnesium base cored-wire comprises foreskin and core, and the external diameter of cored-wire is 6-20mm, and the thickness of foreskin is 0.2-1.5mm; The foreskin of cored-wire can be iron sheet or copper sheet; The material that the cored-wire core is wrapped is to contain the material that granularity is a 0.2-1.2mm passive metal magnesium.
Further be that the foreskin of described cored-wire is preferably iron sheet.
Further be, the material that described cored-wire core is wrapped is pure passive metal magnesium, and this cored-wire is called pure passive metal magnesium cored-wire.
Further be, the material that described cored-wire core wrapped is the mixture of pulvis such as pure passive metal magnesium and other desulfurization, and this cored-wire is called passive metal magnesium base composite core-spun yarn.
Further be, described pure passive metal magnesium cored-wire, its external diameter is 10-16mm preferably, and its thickness of scale is 0.4-0.6mm preferably.
Further be, described passive metal magnesium base composite core-spun yarn, its external diameter is 14-18mm preferably, and its thickness of scale is 0.3-0.6mm preferably.
Compared with the prior art, the utlity model has following obvious advantage.
1, with the low obvious economic of passive metal magnesium base cored-wire desulphurization cost, reduce the temperature drop of molten iron or molten steel, reduce splash;
2, with the desulfurization of passive metal magnesium base cored-wire shoot straight, technology is simple, easy to operate;
3, with the desulfurization of passive metal magnesium base cored-wire, pollute and lack, it is safe and reliable to splash less;
4, passive metal magnesium base cored-wire good seal, the Transport Safety height;
5, with the desulfurization of passive metal magnesium base cored-wire, its required equipment volume is little, and cost is low;
6, with the desulfurization of passive metal magnesium base cored-wire, action required personnel are few, and labour intensity is low;
Accompanying drawing 1 is a passive metal magnesium base cored-wire schematic cross-section described in the utility model.
Below in conjunction with drawings and Examples the technical solution of the utility model is further specified.
A kind of passive metal magnesium base cored-wire comprises foreskin 1 and core 2, and the outer diameter D of cored-wire is 6-20mm, and the thickness δ of foreskin is 0.2-1.5mm; The foreskin 1 of cored-wire can be iron sheet or copper sheet; The material that cored-wire core 2 is wrapped is to contain the material that granularity is a 0.2-1.2mm passive metal magnesium.
Further be that the foreskin 1 of described cored-wire is preferably iron sheet.
Further be, the material that described cored-wire core 2 is wrapped is pure passive metal magnesium, and this cored-wire is called pure passive metal magnesium cored-wire.
Further be, the material that described cored-wire core 2 wrapped is the mixture of pulvis such as pure passive metal magnesium and other desulfurization, and this cored-wire is called its composite core-spun yarn of passive metal magnesium.
Further be, described pure passive metal magnesium cored-wire, its outer diameter D is 10-16mm preferably, and its thickness of scale δ is 0.4-0.6mm preferably.
Further be, the U.S. basic composite core-spun yarn of described passive metal, its outer diameter D is 14-18mm preferably, and its thickness of scale δ is 0.3-0.6mm preferably.
