Abstract
The utility model relates to a composite cored wire. The composite cored wire is formed by combing a calcium alloy wire, a first layer of steel strip, a powder particle layer and a second layer of steel strip, wherein the powder particle layer is arranged between the first layer and the second layer of steel strips and the calcium alloy wire is arranged in the first layer of steel strip. Since two layers of steel strips are arranged in the cored wire, the reaction time of the cored wire can be prolonged, when the cored wire is inserted at a lower speed in the molten steel, the powder layer can be sufficiently reacted with the molten steel, the phenomenon of the splashing is avoided and the yield of the steel can be greatly improved.
Description
Technical field
The utility model relates to a kind of composite core-spun yarn, belongs to metallurgical refining techniques field.
Background technology
Cored-wire, can cleaning molten steel for steel-making, changes inclusion morphology, improves molten steel castability and mechanical property, and can significantly improve the recovery rate of calcium alloy, reduces steel-making cost.In existing traditional metallurgical technology, the cored-wire using mainly contains silicon-calcium wire, calcium iron wire and the pure calcium core-spun yarn of real core, using in silicon-calcium wire, calcium iron wire process, easily occurs phenomenon inhomogeneous or broken string, makes steel quality fluctuation larger; The pure calcium core-spun yarn of real core has some improvement with respect to first two cored-wire, but because the outer wall of the pure calcium core-spun yarn of existing real core only has one deck, when in the molten steel of cored-wire being inserted to thousands of degree, when cored-wire is not also deep into the furnace bottom of molten steel, the metal shell of metal cored wire is complete by molten steel fusing in halfway, like this, the calcium alloy of metal cored wire inside can produce a large amount of gas in reaction process, thereby can form larger splash, easily cause security incident, meanwhile, also reduced the recovery rate of calcium.
Utility model content
The purpose of this utility model is to design in order to address the above problem to provide a kind of composite core-spun yarn; This cored-wire is provided with two-layer steel band, can extend like this reaction times of cored-wire, in cored-wire inserts molten steel under lower speed time, can make powder layer fully react with molten steel, avoids occurring splash phenomenon; This cored-wire is simple in structure, reasonable in design, and long reaction time can improve the recovery rate of steel greatly.
In order to achieve the above object, the utility model is realized by following technique means:
A kind of composite core-spun yarn, it is combined by calcium alloy silk, the first layer steel band, powder granular layer, second layer steel band, it is characterized in that: between the first layer steel band and second layer steel band, be provided with powder granular layer, be provided with calcium alloy silk in the first layer steel band.
Powder particle in described powder granular layer is the wherein one in Ca-Fe alloy particle, calloy particle, silicocalcium particle, aluminum alloy granule, calcium alloy particle, magnesium alloy particles.
The utlity model has following beneficial effect:
1, this cored-wire is provided with two-layer steel band, can extend like this reaction times of cored-wire, in cored-wire inserts molten steel under lower speed time, can make powder layer fully react with molten steel, avoids occurring splash phenomenon;
2, this cored-wire is simple in structure, reasonable in design, and long reaction time can improve the recovery rate of steel greatly.
