Abstract
The utility model relates to a high-efficiency composite cored wire which comprises a solid pure metal calcium wire rod (1), a powder layer (2) and a sheet steel cladding (3), wherein the external surface of the solid pure metal calcium wire rod (1) is coated by the powder layer (2), and the exterior of the powder layer (2) is coated by the sheet steel cladding (3). Compared with a calcium-silicon cored wire, a calcium-iron cored wire and a pure-calcium cored wire, the high-efficiency composite cored wire provided by the utility model has the advantages that the accurate calcium content, non-wire breakage and high yield of the pure-calcium cored wire are reserved, simultaneously the reaction depth of calcium in molten steel is increased, the splashing is greatly reduced in the process of adding the calcium to the molten steel, the yield of calcium is further increased, simultaneously the using safety is improved, and increasing nitrogen of the molten steel is reduced. As the wire diameter is increased, the slipping problem is avoided in the wire feeding process.
Description
Technical field
The utility model relates to steelmaking technical field, specifically a kind of efficient composite core-spun yarn.
Background technology
In the seventies in 20th century; Begin to have produced the technology that in the liquid steel refining process, adds calcium metal; The adding of calcium metal can reduce harmful element content such as oxygen and the sulphur in the molten steel, helps the raising of steel, and changes the composition form of inclusion in the molten steel; Nozzle clogging takes place when avoiding cast aluminum killed steel, changes steel mechanics performance.
Technology the earliest is directly to add the calcium silk; Process modification had afterwards adopted the powder core spun yarn to add the technology of molten steel in molten steel, jetting calcium alloy more afterwards, and what grew up in nearly 2 years is the technology that joins molten steel with pure calcium core-spun yarn.
The characteristics of powder core spun yarn and pure calcium core-spun yarn see the following form:
Can find out from table; No matter be to adopt traditional product or product innovation; All exist some problems, pure calcium line has solved many deficiencies of powder core spun yarn as the current up-to-date technology that substitutes the powder core spun yarn; But, promptly use the phenomenon of the molten steel nitrogen pick-up that process safe hidden danger and invar water projection bring also owing to acutely produced new problem with molten steel reaction.
In addition, directly compare with the line that wire feeder was suitable for that generally use the Iron And Steel Plant production scenes, pure calcium line line footpath partially carefully; Phenomenons such as silk skids often appear feeding in feeding the silk process; Let the field staff can not accurately grasp feed quantity, can not accurately grasp feeding speed, the result does not reach best yield.
Summary of the invention
The purpose of the utility model is based on the advantage that pure calcium core-spun yarn yield is high, use cost is low, and is compound with corresponding cold burden between pure calcium silk and steel band, forms the multilayered structure of coating layer, middle bisque, metal core layer.
The efficient composite core-spun yarn of the utility model comprises: solid pure metal calcium silk rod. the outside surface cladding powder layer of solid pure metal calcium silk rod; Powder bed coats the sheetmetal covering outward.
Said powder bed is one of reduced iron powder, ferro-silicon powder, calcium-aluminate or silica flour.
Said sheetmetal covering is a cold-rolled steel strip.
The advantage of the efficient composite core-spun yarn of the utility model is:
1. because many one deck powder between calcium silk and the sheetmetal can slow down the gasification rate after calcium metal gets into molten steel, let calcium reaction, thereby reach the effect that improves yield, reduces splash in the molten steel depths;
2. owing to reduced splash, can bring the benefit that reduces potential safety hazard and reduce molten steel nitrogen pick-up simultaneously;
3. compare with pure calcium core-spun yarn; Because structural changes has increased cored-wire line footpath, new and effective composite core-spun yarn can adapt to the wire feeder requirement that present steel mill generally uses; Thereby increase feeding speed, further reach the effect that reduces splash, improves the calcium yield;
4. compare with silico-calcium, calcium iron powder cored-wire; Owing to contain the calcium metal core in the clad structure; The unit calcium content of the efficient composite core-spun yarn of the utility model is more accurate, does not have " hollow " or powder calcium agent content fluctuation problem, and the calcium treating processes the broken string problem can not occur yet.
Description of drawings
Fig. 1 is the structural representation of the efficient composite core-spun yarn of the utility model.
Embodiment
According to shown in Figure 1, a kind of efficient composite core-spun yarn comprises: solid pure metal calcium silk rod 1, the outside surface cladding powder layer 2 of solid pure metal calcium silk rod 1, the powder bed 2 outer sheetmetal coverings 3 that coat.
Said powder bed is one of reduced iron powder, ferro-silicon powder, calcium-aluminate or silica flour.
Said sheetmetal covering is a cold-rolled steel strip.
Claims (3)
1. efficient composite core-spun yarn comprises: solid pure metal calcium silk rod ⑴, coat sheetmetal covering ⑶ outward, and it is characterized in that: solid pure metal calcium silk rod ⑴ and coat outward between the sheetmetal covering ⑶ and be coated with powder bed ⑵.
2. efficient composite core-spun yarn according to claim 1 is characterized in that: said powder bed ⑵ is reduced iron powder, ferro-silicon powder, calcium-aluminate or silica flour.
3. efficient composite core-spun yarn according to claim 1 is characterized in that: said sheetmetal covering ⑶ is a cold-rolled steel strip.
