Abstract
The utility model relates to a solid-core pure-calcium core-spun yam with a powder interlayer. The core-spun yam consists of a solid-core calcium wire, a powder interlayer and a steel belt, wherein the powder interlayer is arranged in the steel belt; and the powder interlayer is internally inlaid with the solid-core calcium wire. According to the core-spun yam, the powder interlayer is arranged between the steel belt and the solid-core calcium wire; filler in the powder interlayer can be selected as required; different effects can be achieved by filling different composites; and the core-spun yam is low in production cost and convenient to use. When the core-spun yam is adopted as an additive to smelt metals, the yield of calcium can be enhanced, the removal effect on oxygen or occluded foreign substances in molten steel solution is good, and therefore, the aims of adjusting the ingredients of the molten steel solution and enhancing the cleanliness and the refining effect of the molten steel solution are achieved.
Description
Technical field
The utility model relates to a kind of pure calcium core-spun yarn of real core with powder interlayer, belongs to metallurgical refining additive technical field.
Background technology
In the smelting steel production process, a large amount of oxygen can appear in the molten steel, because the oxygen in the steel solution can make and produce a large amount of bubbles in the steel billet, influence 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 minor amounts of additives and additive, make itself and the interior inclusion of molten steel produce chemical reaction, to reach inclusion and the oxygen bubble of removing in the 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, employed cored-wire mainly contains powdery silicon-calcium wire, iron calcium line and aluminium calcium line, and these conventional bag heart yearns in use break easily, can influence the cleanliness factor of metallic solution; 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 preceding several cored-wires, but the effect of removing the interior oxygen of molten steel liquation or inclusion is unsatisfactory, does not reach high-level technical requirements.
The utility model content
The purpose of this utility model is to design in order to address the above problem a kind of pure calcium core-spun yarn of real core with powder interlayer is provided; This cored-wire is provided with the powder interlayer between steel band and real core calcium silk, the weighting material in the powder interlayer can be selected as required, fills different compositions and can reach different effects; This cored-wire production cost is low, easy to use, uses this cored-wire as the additive metal smelting, can improve the recovery rate of calcium, better to the oxygen in the molten steel liquation or inclusion removing effect, thus reach the composition of regulating molten steel, improve the purpose of molten steel cleanliness factor and refining effect.
In order to achieve the above object, the utility model is realized by following technique means:
A kind of pure calcium core-spun yarn of real core with powder interlayer, it is combined by real core calcium silk, powder interlayer, steel band, it is characterized in that: be provided with the powder interlayer in steel band, be inlaid with real core calcium silk in the powder interlayer.
The powder of filling in the described powder interlayer can be selected wherein a kind of of aluminium powder, AD powder, magnesia powder, calcium oxide powder.
The powder of filling in the described powder interlayer is the mixture of magnesia powder, calcium oxide powder.
The utlity model has following beneficial effect:
This cored-wire is provided with the powder interlayer between steel band and real core calcium silk, the weighting material in the powder interlayer can be selected as required, fills different compositions and can reach different effects; This cored-wire production cost is low, easy to use, uses this cored-wire as the additive metal smelting, can improve the recovery rate of calcium, better to the oxygen in the molten steel liquation or inclusion removing effect, thus reach the composition of regulating molten steel, improve the purpose of molten steel cleanliness factor and refining effect.
