Abstract
The invention relates to a solid metal cored wire and a preparation method thereof. The solid metal cored wire consists of a metal shell and an inner core, wherein the inner core is inlaid in the metal shell; the metal shell is made of low-carbon steel or a stainless steel metal material, and the inner core is made of a calcium wire. The preparation method of the solid metal cored wire comprises the following steps of winding a low-carbon steel or stainless steel strip of which the width is 24-44mm and the thickness is 1-2mm into an arc shape by using a linear pipe welder, then inserting the inner core into the arc-shaped steel strip, winding the arc-shaped steel strip into a round shape, then welding gaps between buckling connections of the round steel strip by using a high-frequency welder or an argon arc welder, then performing extrusion and shaping, and finally performing reeling package by using a re-reeling machine to obtain the solid metal cored wire disclosed by the invention. By using the solid metal cored wire to smelt metals, the content of excessive oxygen or other components in molten metal can be adjusted, the temperature loss in the refining process of molten steel is reduced, and the cleanliness of the molten steel is improved.
Description
Technical field
The present invention relates to a kind of real core metal cored-wire and preparation method thereof, belong to metallurgical refining techniques field.
Background technology
In Metal smelting production process, in molten metal, there will be oxygen, oxygen is divided into dissolved oxygen and total oxygen, and dissolved oxygen exists with bubble, and total oxygen is present in non-metallic inclusion.The dissolved oxygen content reducing in molten metal can improve the surface quality of steel billet and eliminate bubble, reduces whole oxygen amount and can remove the oxide impurity in molten metal, improves the cleanliness factor of steel.Metal cored wire is mainly used in Metal smelting production process, in order to remove unwanted inclusion and the oxygen bubble in the molten metal being smelted, improve the cleanliness factor of steel, adjusting is smelted the composition of molten metal, generally in smelting process, in the molten metal being melted, add some a small amount of additive and additives, make itself and molten metal produce chemical reaction, to reach inclusion and the oxygen bubble of removing in molten metal, improve cleanliness factor, regulate, improve the object of the toughness of steel.
Metal cored wire is exactly a kind of additive using in order to achieve the above object when Metal smelting.In existing traditional metallurgical technology, the metal cored wire using is because its outer wall is thinner, in the time of in the iron and steel liquation of metal cored wire being inserted to thousands of degree, when metal cored wire is not also deep into the furnace bottom of iron and steel liquation, the metal shell of metal cored wire is complete by molten steel fusing in halfway, like this, the material of metal cored wire inside can only produce and react with the upper part of iron and steel liquation, and lower part of iron and steel liquation is owing to can not get the reaction of metal cored wire inner material, can make iron and steel liquation occur inhomogeneous and fault-layer-phenomenon, directly have influence on the quality of iron and steel.
Summary of the invention
The object of the invention is to design in order to address the above problem provides a kind of real core metal cored-wire and preparation method thereof, this metal cored wire is combined by outer layer metal shell and inner core two sections of material, the shell of metal cored wire adopts low-carbon (LC) steel or stainless steel to make, and inner core adopts high purity metal calcium to make; Use this reality core metal cored-wire metal smelting, can regulate the oxygen that exceeds standard in molten metal or the content of other compositions, save the refining treatment time, reduce the temperature loss in molten steel refining process, improve the cleanliness factor of molten steel; Because shell employing soft steel or the stainless material of real core metal cored-wire are made, shell tube wall is smooth, thicker, be difficult for being melted rapidly by the molten steel of high temperature, so real core metal cored-wire can be deep into the bottom of molten steel, extend the residence time, make fully to react with molten steel after the wire melting in cored-wire, specific absorption is high, reach the composition that regulates molten steel, improve molten steel cleanliness factor, improve the object of molten steel refining effect; Due to this reality core metal cored-wire steady quality, be easy to keeping and store in addition, because of its higher specific absorption, can reduce the consumption of metal cored wire, reduce the processing cost of metal smelting, reach the object of Synergistic and energy-saving.
In order to achieve the above object, the present invention realizes by following technique means:
A kind of real core metal cored-wire and preparation method thereof, this reality core metal cored-wire is comprised of metal shell and inner core two portions, it is characterized in that: in metal shell, be inlaid with inner core; Metal shell adopts soft steel or stainless steel metal material to make, and inner core adopts calcium silk to make; The outer dia of metal shell is 8～15mm, and the thickness of metal shell is 1～2mm;
This reality core metal cored-wire its preparation method is as follows:
Using straight line tube-welding machine is soft steel or the stainless steel belt that 24～44mm, thickness are 1～2mm by width, roll into circular-arc, then inner core is inserted in circular-arc steel band, again circular-arc steel band is bent to circle, then use high-frequency induction welder or the argon welder gap between circular steel band is fastened and connected to weld, push again, shaping, finally use rewinding machine to coil packing, make real core metal cored-wire of the present invention.
Described inner core is not limited to calcium silk, according to smelting need of production, also can select magnesium silk, aluminium wire, titanium silk one of them.
The present invention has following beneficial effect:
1, use this reality core metal cored-wire metal smelting, can regulate the oxygen that exceeds standard in molten metal or the content of other compositions, save the refining treatment time, reduce the temperature loss in molten steel refining process, improve the cleanliness factor of molten steel;
2, the shell due to real core metal cored-wire adopts soft steel or stainless material to make, shell tube wall is smooth, thicker, be difficult for being melted rapidly by the molten steel of high temperature, so real core metal cored-wire can be deep into the bottom of molten steel, extend the residence time, make fully to react with molten steel after the wire melting in cored-wire, specific absorption is high, reach the composition that regulates molten steel, improve molten steel cleanliness factor, improve the object of molten steel refining effect;
3, in addition due to this reality core metal cored-wire steady quality, be easy to keeping and store, because of its higher specific absorption, can reduce the consumption of metal cored wire, reduce the processing cost of metal smelting, reach the object of Synergistic and energy-saving.
