Abstract
The utility model relates to the technical field of refined steels, in particular to a silicon-calcium cored wire for refined steels. The silicon-calcium cored wire comprises a bearing tube manufactured by pressing narrow steel strips and is characterized in that a silicon powder layer is arranged in the bearing tube, and a calcium core wire is arranged in the central area of the silicon power layer. Calcium and silicon can be conveniently added into molten steel and molten iron by the cored wire formed by pressing and wrapping the narrow steel strips, alloy yield can be improved by a large margin, smelting cost is reduced, smelting time is shortened, and compositions are controlled precisely.
Description
Technical field
The utility model relates to the refining steel technical field, particularly a kind of silico-calcium cored-wire that is used for the refining steel.
Background technology
In modern times in the metallurgical process; Usually need in molten steel, add all kinds of SOLVENTS, microalloy etc.; Directly these solvents, microalloy are thrown into molten steel and can produce very big waste, in order to improve the utilising efficiency of microalloy, solvent, people have invented the adding method with cored-wire.Calcium series cored-wire is widely used in ladle deoxidation and handles, with the electromagnetism orientation characteristic of the intensity, toughness and the high-performance silicon steel that improve special steel etc.
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.
Summary of the invention
To above-mentioned technical problem, the utility model provides a kind of cored-wire that is used for adding to steel melting furnace alloying substance.
The utility model is realized through following technical scheme:
The silico-calcium cored-wire, it comprises that forming carrying by the narrow steel strip compacting manages, it is characterized in that: be provided with silicon powder layer in the described carrying pipe, the central zone of silicon powder layer is provided with the calcium heart yearn.
The thickness of described narrow steel strip is 0.4mm, and width is 55mm.
In sum, the cored-wire that the utility model is suppressed and is wrapped to form through narrow steel strip joins calcium and silicon in molten steel or the iron liquid easily, can improve yield of alloy by a relatively large margin, reduces smelting cost, shortens the heat, and accurately controls composition.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model;
1 for carrying pipe among the figure, and 2 is silicon powder layer, and 3 is the calcium heart yearn.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Silico-calcium cored-wire as shown in Figure 1, the silico-calcium cored-wire, it comprises that forming carrying by the narrow steel strip compacting manages 1, is provided with silicon powder layer 2 in the described carrying pipe 1, the central zone of silicon powder layer 2 is provided with calcium heart yearn 3.
The thickness of described narrow steel strip is 0.4mm, and width is 55mm.
In sum, the cored-wire that the utility model is suppressed and is wrapped to form through narrow steel strip joins calcium and silicon in molten steel or the iron liquid easily, can improve yield of alloy by a relatively large margin, reduces smelting cost, shortens the heat, and accurately controls composition.
