Abstract
The utility model relates to a double-layer solid-core pure-calcium core-spun thread is formed by combining solid-core calcium threads, a first layer of steel belt and a second layer of steel belt, the first layer of steel belt is arranged in the second layer of steel belt, and the solid-core calcium threads are inlaid in the first layer of steel belt. A metal housing of the core-spun thread is formed by combining two layers of steel belts, and the high-purity solid-core calcium threads are arranged in the middle of the metal housing; in the process of producing the core-spun thread, the metal housing at the outer wall of the core-spun thread is easily bent, good in flexibility and close to fit; and in the feeding process of metal smelting, the core-spun thread is small in resistance when passing through a thread feeder, stable in feeding speed and accurate in feeding quantity, the core-spun thread can fully react at the bottom of molten steel, so as to achieve the purposes of regulating the substances of the molten steel, improving the cleanness of the molten steel and enhancing the refining effect of the molten steel.
Description
Technical field
The utility model relates to the pure calcium core-spun yarn of the real core of a kind of bilayer, belongs to metallurgical refining techniques field.
Background technology
In the smelting steel production process, in molten steel, a large amount of oxygen can appear, because the oxygen in steel solution can make a large amount of bubble of generation in steel billet, affect the surface quality of steel billet and the cleanliness factor of steel, therefore, in smelting process, in the molten steel that is melted, add some a small amount of additive and additives, make itself and the interior inclusion of molten steel produce chemical reaction, to reach inclusion and the oxygen bubble of removing in molten steel, improve the steel cleanliness factor, regulate, improve the purpose of the toughness of steel.
Cored-wire is exactly a kind of additive that uses in order to achieve the above object when smelting steel.in existing traditional metallurgical technology, the cored-wire that uses mainly contains powdery silicon-calcium wire, iron calcium line and aluminium calcium line, and in smelting process, these traditional cored-wires easily break, and can affect the cleanliness factor of metallic solution, reduce the recovery rate of calcium, in addition, the pure calcium core-spun yarn of the real core of a kind of individual layer has also appearred in existing market, the pure calcium core-spun yarn of the real core of this individual layer has some improvement with respect to front several cored-wires, 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 thousands of degree, when cored-wire also is not deep into the furnace bottom of molten steel, the metal shell of cored-wire is complete by molten steel fusing in halfway, like this, the material of metal cored wire inside can only produce reaction with the upper part of molten steel, and meeting produces a large amount of gas in reaction process, gas when flowing out smelting furnace because energy is larger, just can carry a certain amount of molten steel and slag, thereby can form larger splash, easily cause security incident, in order to extend the reaction times of cored-wire, make cored-wire extend to the bottom of steel solution, someone taked the method for the outer wall thickening of cored-wire is extended the reaction times of cored-wire afterwards, but because the outer wall of cored-wire is too thick, in the process of process for processing cored-wire, the crooked interlock of the outer wall of cored-wire is very difficult, is difficult to process for processing and goes out tight, the round and smooth cored-wire of outer wall interlock.In order thoroughly to remove oxygen or the inclusion in the molten steel liquation, reach the composition of regulating molten steel, improve the purpose of molten steel cleanliness factor and refining effect, people never stopped for the research of the treatment agent that uses in the Metal smelting process or additive.
The utility model content
The purpose of this utility model is to design in order to address the above problem to provide the real core of a kind of bilayer pure calcium core-spun yarn; The metal shell of this cored-wire is combined by two-layer steel band, and highly purified real core calcium silk is used at the middle part; In the process of process for processing cored-wire, the outer wall metal shell of cored-wire is easily crooked, and snappiness is good, and interlock is tight; This cored-wire is in the adition process of Metal smelting, during through wire feeder, resistance is little, feeding speed is stable, the quantity of feeding is accurate, and cored-wire can be deep into the bottom of molten steel and carry out complete reaction, reaches the composition of regulating molten steel, improve the molten steel cleanliness factor, improve the purpose of molten steel refining effect.
In order to achieve the above object, the utility model is realized by following technique means:
The pure calcium core-spun yarn of the real core of a kind of bilayer, it is combined by real core calcium silk, the first layer steel band, second layer steel band, it is characterized in that: be provided with the first layer steel band in second layer steel band, be inlaid with real core calcium silk in the first layer steel band.
The utlity model has following beneficial effect:
1, the metal shell of this cored-wire is combined by two-layer steel band, and highly purified real core calcium silk is used at the middle part; In the process of process for processing cored-wire, the outer wall metal shell of cored-wire is easily crooked, and snappiness is good, and interlock is tight;
2, this cored-wire is in the adition process of Metal smelting, during through wire feeder, resistance is little, feeding speed is stable, the quantity of feeding is accurate, and cored-wire can be deep into the bottom of molten steel and carry out complete reaction, reaches the composition of regulating molten steel, improve the molten steel cleanliness factor, improve the purpose of molten steel refining effect.
