Abstract
The utility model relates to a cored wire, in particular to an aluminum-calcium cored wire. The aluminum-calcium cored wire comprises an outer covering layer. A separating layer is arranged in the outer covering layer and divides the inside of the outer covering layer into two filling layers, aluminum is filled in one filling layer, calcium is filled in the other filling layer, and the outer covering layer is made of low-carbon steel. By adopting the structure, the calcium and the aluminum can be conveniently added in molten steel or molten iron through the aluminum-calcium cored wire, the alloy yield can be improved remarkably, the smelting cost is reduced, the smelting time is shortened, and components are controlled accurately.
Description
Technical field
The utility model relates to a kind of cored-wire, particularly a kind of aluminium calcium core-spun yarn.
Background technology
Cored-wire is that desire is added the various additives fragmentations in molten steel or the iron liquid, with surrounding layer it is included as a matrix material with random length then.
Cored wire technology is a kind of external refining means that on the spraying metallurgy technology basis, grow up the eighties.Cored-wire is applicable to steel-making and casting.Be used for steel-making and can purify the steel inclusion morphology, improve the molten steel castability, improve the use properties of steel, and can significantly improve the yield of alloy, reduce alloy consumption, reduce steel-making cost, remarkable in economical benefits.
Cored-wire has following characteristics: 1, help easy oxidation element of adjustment and control and content of elements, can improve yield of alloy by a relatively large margin, reduce smelting cost, shorten the heat, accurately control composition.2, play the effect that pure molten steel and part change inclusion character and form, improve steel quality, improve the casting state.3, the required mechanical means of cored-wire line feeding is simple and reliable, and floor space is few.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of cored-wire that can in molten steel or iron liquid, add calcium and aluminium easily.
For solving above-mentioned technical problem, the aluminium calcium core-spun yarn of the utility model comprises surrounding layer, is provided with separate layer in the said surrounding layer; Said separate layer is divided into two packing layers with surrounding layer inside, fills calcium in the filling aluminum in the packing layer, another packing layer.
Said surrounding layer adopts soft steel.
After adopting said structure, can easily calcium and aluminium be joined in molten steel or the iron liquid, can improve yield of alloy by a relatively large margin, reduce smelting cost, shorten the heat, accurately control composition through the aluminium calcium core-spun yarn.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Among the figure: 1 is surrounding layer, and 2 is separate layer, and 3 is the aluminium packing layer, and 4 is the calcium packing layer
Embodiment
Aluminium calcium core-spun yarn as shown in Figure 1 comprises surrounding layer 1, and said surrounding layer 1 adopts soft steel, and elder generation rolls soft steel but do not seal.In the surrounding layer of rolling, be provided with separate layer 2; Said separate layer 2 is divided into two packing layers with surrounding layer 1 inside, and filling aluminum forms aluminium packing layer 3 in the packing layer; Fill calcium in another packing layer and form calcium packing layer 4.Behind to be filled the finishing, surrounding layer 1 sealing is got final product.
As depicted in figs. 1 and 2, the position of separate layer 2 can be provided with according to ratio part of aluminium packing layer 3 and calcium packing layer 4.
Certainly, the surrounding layer 1 of the utility model also can adopt other materials that is suitable for, and such conversion all drops within the scope of the utility model protection.
Claims (2)
