Abstract
The utility model discloses a compound core of a metal calcium aluminum cored wire for steelmaking deoxidization, comprising a metal calcium wire, wherein the outside of the metal calcium wire is enwrapped by an aluminum belt layer, the diameter of the metal calcium wire is 5-8mm, and the thickness of the aluminum belt layer is 0.7-1mm. The compound core disclosed by the utility model has the advantage of high strength; because the compound core is formed by enwrapping the aluminum belt layer outside of the metal calcium wire, wire feeding depth can be lower than the critical depth of calcium, and before calcium steam is formed, the calcium already reacts with molten steel to improve calcium yield, effectively prevent calcium burning loss, and greatly reduce cost of tons of steel; and further, the added aluminum belt can be applied to the deoxidization of the molten steel to improve the purity of the molten steel.
Description
Technical field
The utility model relates to deoxidation in steel making calcium metal aluminium core cabling wire, especially relates to the compound core body that a kind of deoxidation in steel making is used the calcium metal aluminium core cabling wire.
Background technology
With the cored-wire form, molten steel being carried out calcium and process, is to begin to develop appearance late 1970s, and China starts from the initial stage eighties to the research of wire-feeding technique.Through the development of nearly 30 years, now become indispensable important step in modern steel production, external refining equipment has all been equipped by nearly all large-scale steel mill.Cored-wire as the principal item of line feeding, in recent years, is that large development is all being arranged on output or on quality and kind.Although Development and Production silicocalcium cored-wire, calcium iron wire, pure calcium line etc., still can not satisfy the needs of all steel grade refinings fully in actual production.The core body of traditional calcium-aluminium core cabling wire is calcium grain, aluminum shot, the outer wrap steel band, because the thickness of steel band is no more than 0.4mm, during line feeding, do not reach the critical depth that calcium exists with liquid form and just react complete in molten steel, there is part metals calcium just to run away with the form of calcium steam before reaction, causes the specific absorption of calcium very low.
Summary of the invention
The purpose of this utility model is to provide that a kind of intensity is high, can reach the following deoxidation in steel making of the critical depth of calcium during line feeding with the compound core body of calcium metal aluminium core cabling wire.
For achieving the above object, the utility model can be taked following technical proposals:
Deoxidation in steel making described in the utility model comprises the calcium metal silk with the compound core body of calcium metal aluminium core cabling wire, and the outer wrap of described calcium metal silk has the aluminium strip layer.
The diameter of described calcium metal silk is 5-8mm, and the thickness of described aluminium strip layer is 0.7-1mm.
The utility model has the advantage of that intensity is high, compound core body in the formation of calcium silk external parcel aluminium strip layer, can reach below the critical depth of calcium during line feeding, before can not form calcium steam, calcium just reacts with molten steel, improve the recovery rate of calcium, effectively avoided the scaling loss of calcium, greatly reduced a ton steel-making cost; The aluminium strip that adds simultaneously can also first carry out deoxidation to molten steel, has improved the purity of molten steel.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, deoxidation in steel making described in the utility model comprises that with the compound core body of calcium metal aluminium core cabling wire diameter is the calcium metal silk 1 of 5-8mm, and in the outer wrap of calcium metal silk 1, thickness being arranged is the aluminium strip layer 2 of 0.7-1mm.When manufacturing cored-wire, first with aluminium strip layer 2 with calcium metal silk 1 parcel, then they are compressed and are wound in the coil of wire with the thick steel band 3 of 0.35-0.80mm and get final product, the diameter of finished product cored-wire is 7.1-11.6mm.
Claims (2)
1. the compound core body of a deoxidation in steel making use calcium metal aluminium core cabling wire, comprise calcium metal silk (1), and it is characterized in that: the outer wrap of described calcium metal silk (1) has aluminium strip layer (2).
2. deoxidation in steel making according to claim 1 is with the compound core body of calcium metal aluminium core cabling wire, and it is characterized in that: the diameter of described calcium metal silk (1) is 5-8mm, and the thickness of described aluminium strip layer is 0.7-1mm.
