Abstract
The utility model discloses a pure calcium/aluminum composite core-spun thread, which comprises a solid pure metal calcium wire or rod (1), and a steel strip layer (3) coated outside the middle layer, wherein an aluminum metal layer (2) is coated between the solid pure metal calcium wire or rod (1) and the steel strip layer (3) coated outside the middle layer. The pure calcium/aluminum composite core-spun thread has the advantages that the pure calcium/aluminum composite core-spun thread retains the advantages that the pure calcium core-spun thread has a precise content of calcium, no breaking and high yield, as well as increases the reaction depth of calcium in liquid steel, greatly reduces sputtering of the liquid steel during the feeding of calcium, further increases the yield of calcium, simultaneously improves the safety in use, and improves the refining effect of the liquid steel.
Description
Technical field
The utility model relates to steelmaking technical field, and specifically the mixture of a kind of parcel aluminium powder (grain), aluminium powder (grain) and other metals or aluminium strip be as cooling packing material, and the compound cored-wire of calcium metal silk (rod).
Background technology
The technique that adds calcium metal in the liquid steel refining process is referred to as the calcium treatment process.The harmful element content such as the oxygen that can reduce in molten steel the adding of calcium metal and sulphur are conducive to the raising of steel product quality, and change the composition form of inclusion content in melting steel, and nozzle clogging occurs when avoiding cast aluminum killed steel, change steel mechanics performance.
The technique of very early time is directly to drop into calcium alloy in molten steel; Process modification afterwards is the calcium alloy of jetting in molten steel, then has adopted afterwards the powder core spun yarn to add the technique of molten steel, and what grew up in nearly 2 years is to join the technique of molten steel with the pure calcium core-spun yarn of metal.
The characteristics of powder core spun yarn and pure calcium core-spun yarn see the following form:
As can be seen from the table, no matter be to adopt traditional product or product innovation, all exist problem, pure calcium line is the technique of powder core spun yarn as an alternative, solve many deficiencies of powder core spun yarn, but also owing to acutely having produced new problem with the molten steel reaction, increased the potential safety hazard in the use procedure.
The utility model content
The purpose of this utility model is based on the advantage that pure calcium core-spun yarn recovery rate is high, use cost is low, fills with the metal cold burden between pure calcium silk (rod) and steel band, forms the multilayered structure of coating layer, middle layer, metal core layer.
The pure calcium of the utility model/aluminium composite core-spun yarn comprises: inner core is solid pure metal calcium silk or rod, and the middle layer is that the outside surface of solid pure metal calcium silk or rod is coated with aluminum metal layer, and skin is the steel belt layer of middle layer outer cladding.
Described aluminum metal layer (2) comprising: aluminium powder or grain) layer or coat mixture layer or coating aluminium strip or the aluminum tube layer that is mixed by different ratios by aluminium powder or grain and other powder;
The outside dimension of described pure calcium/aluminium composite core-spun yarn is 7mm～20mm.
The calcium content of described calcium metal silk or rod 〉=90%, diameter is 5mm～15mm.
The granularity of aluminium powder or grain is 0～3mm;
The granularity of the mixture that is mixed by different ratios with other powder by aluminium powder or grain is 0～3mm
Al zone thickness is 1mm～15mm; Aluminium strip can be rolled into aluminum pipe
The aluminium powder in described middle layer or grain or the mixture that is mixed by different ratios with other powder by aluminium powder or grain or the consumption of aluminium strip are 1g/m～450g/m.
Describedly can be mixed with arbitrary proportion by the mixture layer that different ratios mixes with other powder by aluminium powder or grain, but aluminium powder or, the aluminum content of aluminium strip 〉=90%.
Described steel band covering is cold-rolled steel strip, and width is 28mm～70mm, and thickness is 0.2mm～0.9mm.
The advantage of the pure calcium of the utility model/aluminium composite core-spun yarn is:
1. due to many one deck middle layers between calcium silk (rod) and steel band, after the line body enters molten steel, the middle layer first contacts molten steel, heat absorption is melted in the middle layer under the high temperature of molten steel, simultaneously the metal pair calcium in the middle layer is dissolved with promoter action in molten steel, thereby reduced the gasification rate after calcium metal enters molten steel aspect two of thermal conduction and decalescences, allowed calcium in molten steel depths reaction, thereby reach the effect that improves recovery rate, reduces splash;
2. owing to having reduced splash, can reduce the potential safety hazard of refining process, and provide better refining condition for liquid steel refining;
3. compare with silico-calcium, calcium iron powder cored-wire, owing to containing metal calcium core in clad structure, the unit calcium content of pure calcium of the present utility model/aluminium composite core-spun yarn 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.
