Description

[0001] Clad steel wire and method [0002]
The present invention relates to a clad steel wire and a method of manufacturing the same, and more particularly, to a method of manufacturing a steel wire having excellent corrosion resistance by improving bonding properties between a steel wire and a clad member through a plasma heating process and a spiral cladding process.
Suspension bridges, cable-stayed bridges, and various bridges and wires used in the seabed should be durable. Especially, since the contact of the seawater of the wire is frequent, the wire mainly uses the steel wire. Steel wire is made of steel and has excellent durability, which is often used in bridges and buildings. However, even in the case of steel wire, if the steel wire is frequently exposed to sea water, corrosion of steel wire is required. At this time, corrosion resistance refers to a property in which corrosion does not easily occur.
As a general method for increasing the corrosion resistance of such a steel wire, there are zinc plating, zinc-aluminum alloy plating, and application of grease oil. However, there is a limit in that the useful life of the steel wire is not long. In order to overcome these problems, a method of fabricating a clad steel wire through a clad process has been developed. The clad process refers to a process in which a metal sheet or a material is rolled and mechanically bonded. In other words, it means combining various metals together to take advantage of each metal. Even in the case of a steel wire, a clad steel wire having excellent corrosion resistance can be produced after bonding with a clad molded member and performing a clad process.
As an example of a method of manufacturing such a clad steel wire, Korean Patent Laid-Open Publication No. 2009-0043816 (published on May 07, 2009) discloses an invention relating to a clad wire manufacturing method. Reference will now be made to Fig. 1 for the purpose of describing the invention disclosed below.
The disclosed invention provides a method of manufacturing a U-shaped clad molded member (10), comprising the steps of: forming a U-shaped clad molded member (10) through a first forming roller (20) A step of inserting the wire 12 into the clad molding member 10 by passing the wire 12 through the second forming roller 30 so as to close the open portion of the clad molded member 10 And sealing the welded clad molded member 10 with the welding apparatus 40 and transferring the welded clad molded member 10 to the drawing apparatus 50 and pulling it out in the form of a clad wire 100 Disclose a method for manufacturing a clad wire 100 through a wire.
However, when the clad wire 100 is manufactured in accordance with the disclosed invention, there is a disadvantage that the bonding strength between the bonding surface of the clad molded member 10 and the wire 12 is low and the integrity is poor. Therefore, in the clad processing of the clad molded member 10 and the wire 12, the bonding property between the clad molded member 10 and the wire 12 is made high so as to improve the service life of the clad wire 100, An invention that can increase the corrosion resistance in seawater is needed.
The present invention relates to a clad steel wire and a method for manufacturing the same, and aims to manufacture a steel wire having excellent corrosion resistance by improving bonding properties between a steel wire and a clad member through a plasma heat treatment and a spiral cladding treatment.
In order to achieve the above object, a method of manufacturing a steel wire requiring corrosion resistance includes a first step of plasma-treating a surface of a steel wire, a first step of passing a steel wire through a strip- a third step of plasma-treating the clad steel wire subjected to the second step, a third step of hot-rolling the clad steel wire that has been subjected to the third step, And a fifth step of wire drawing the clad steel wire that has undergone the fourth and fourth steps of machining.
The heating temperature in the first step of the clad steel wire manufacturing method may be 100 to 200 ° C.
The cladding process of the second step of the clad steel wire manufacturing method includes a process of tightly attaching the clad member in a spiral shape along the longitudinal direction of the steel wire which has been subjected to the first step around the steel wire which has been subjected to the first step .
The heating temperature in the third step of the clad steel wire manufacturing method may be 500 to 800 ° C.
The hot rolling process in the fourth step of the clad steel wire manufacturing method may be characterized in that the clad steel wire subjected to the third step is rolled so as to have a sectional area reduction ratio of 5 to 10%.
Further, the clad member of the clad steel wire manufacturing method may be any one of aluminum, stainless steel, titanium, and titanium alloy.
The bonding property between the steel wire and the clad member is improved by the plasma heat treatment on the surface of the steel wire according to the present invention, thereby increasing the corrosion resistance of the clad steel wire and extending the service life.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
2 is a view illustrating a method for manufacturing a clad steel wire according to the present invention. Hereinafter, a method for manufacturing a clad steel wire will be described with reference to FIG.
The prepared steel wire 100 is subjected to a first step S100 in which the surface of the steel wire 100 is subjected to plasma heat treatment 210. First, the steel wire 100 is prepared. At this time, the steel wire 100 is preferably a high strength steel wire 100 having a carbon content of 0.6 to 1.0%. When the carbon content of the steel wire 100 is low, the tensile strength of the clad steel wire is lowered and the service life is shortened. The surface of the prepared high strength steel wire 100 is subjected to a plasma heat treatment 210. The plasma heating process 210 in the first step of the present invention refers to a process in which plasma is applied to the surface of the steel wire 100 to heat the steel wire 100 to 100 to 200 ° C.
Plasma refers to a gas state separated by electrons and positively charged ions at a very high temperature. It is often referred to as the 'fourth state of matter' and has a very high charge separation, resulting in a net charge due to the same number of positive and negative charges. Plasma is used in various fields, and is also used in metal processing. The reason why the plasma heating process 210 is preferable in the present invention is that the heating time of the steel wire 100 is shortened by being heated to an ultra-high temperature as compared with other heating methods. The probability that another impurity is bonded to the steel wire 100 due to shortening of the heating time becomes low. In addition, since the plasma heating is a clean heating source, there is an advantage that the heating environment can be effectively controlled. Because of the advantages of the plasma heating process 210, the final clad steel wire 120 having high corrosion resistance and good quality can be manufactured.
Plasma is generated by the plasma module, and plasma is treated on the surface of the steel wire 100. The reason why the plasma is treated on the surface of the steel wire 100 is that the surface of the steel wire 100 is cleaned by removing the surface foreign substances in the process of joining the steel wire 100 and the clad member 110 later, So as to improve the bonding property between the steel wire 100 and the clad member 110.
When the surface of the steel wire 100 is subjected to the plasma treatment, the steel wire 100 is heated. When the steel wire 100 is heated, the bondability between the steel wire 100 and the clad member 110 increases. At this time, the heating temperature at which the steel wire 100 is heated is preferably 100 to 200 ° C. When the heating temperature of the steel wire 100 is 100 DEG C or less, the bonding surface between the steel wire 100 and the clad member 110 is low and the bonding surface is poor. When the temperature is higher than 200 DEG C, The surface of the steel wire 100 becomes hot and rapidly reacts with oxygen, and an oxide scale phenomenon occurs in which substances such as thin peeling are formed on the surface of the steel wire 100. Due to such an oxidation scale phenomenon, the bonding property between the steel wire 100 and the clad member 110 is reduced. Therefore, in the first step S100 of the present invention, the heating temperature of the steel wire 100 through plasma is preferably 100 to 200 ° C.
The steel wire 101 having been subjected to the first step S100 is subjected to a second step S110 in which the cladding process is performed with the clad member 110. [ Hereinafter, the second step (S110) in the present invention will be described.
Cladding refers to a process in which a metal sheet or a material is rolled and mechanically bonded as described above. In the present invention, the steel wire 101 and the clad member 110 which have undergone the first step are rolled by being rolled up. At this time, the clad member 110 is preferably in a strip state. The term "strip condition" refers to a long and thin band-shaped plate of metal. When the clad member 110 in the strip state is wound around the cylindrical steel wire 101 that has undergone the first step in which the length of the clad member 110 is extended in the longitudinal direction, the contact area between the steel wire 101 and the clad member 110, And the bonding property is excellent. The material of the clad member 110 is preferably any one of aluminum, stainless steel, titanium, and a titanium alloy. Aluminum is a metal element belonging to the 13th group of the periodic table and belonging to 3 cycles, and it has a characteristic that it is not corroded because it is used for a window frame pot. Stainless steel is a general term for corrosion resistant steel, which is made for the purpose of improving the lack of corrosion resistance, which is the biggest shortcoming of iron. It is superior in corrosion resistance and heat resistance to existing carbon steel. Titanium has a very high stiffness and elastic modulus, and is widely used for wire and other industrial materials. It is made of an alloy with iron to form a titanium alloy. Titanium and titanium alloys also have the advantage of excellent corrosion resistance. If the material of the clad member 110 is any one of aluminum, stainless steel, titanium, and titanium alloy, the purpose of the present invention is to meet the object of manufacturing the final clad steel wire 120 requiring corrosion resistance.
In the cladding process 300, generally, the clad member 110 is wrapped around the steel wire 101 that has undergone the first step in a U-shape, and a portion not connected to the end of the clad member 110 is welded The steel wire 101 having been subjected to the first step is joined to the clad member 110 by the U-shaped joining method. However, in the present invention, a spiral processing method is used as an embodiment of the bonding method. 3, the spiral cladding process of the final clad steel wire 120 according to the present invention will be described.
3 is a view showing the state of the clad steel wire 102 after completion of the cladding process 300, that is, the second step. The longitudinal direction of the steel wire 101 that has been subjected to the first step at a certain interval between the clad members 110 by spirally twisting the clad member 110 about the steel wire 101 having been subjected to the first step formed in the longitudinal direction, And then closely attached thereto. At this time, since the clad member 110 spirally twists the steel wire 101 that has been subjected to the first step, the clad member 110 is formed by winding the steel wire 101 in the first step, So that the steel wire 101 is wound.
As described above, the clad member 110 spirally twists the steel wire 101 that has undergone the first step and the conventional method of winding the clad member 110 into the U shape. 4 is a cross-sectional view of the clad steel wire 102 after the second step, and reference is now made to Fig. In the conventional cladding process, the end portion of the clad member 110 must be welded to the upper portion of the steel wire 101 that has been subjected to the first step, so that the clad member 110). The bonding between the steel wire 101 and the clad member 110 in the first step is lowered due to the gap of the clad member 110, resulting in a shortened life span. However, since the spiral cladding process 300 according to the present invention is twisted in a spiral manner, as shown in FIG. 4, the clad member 110 surrounding the steel wire 101 having passed through the first step is inserted into the steel wire The clad member 110 does not need to be welded separately because there is no gap between the clad members 110. [ This structure has an advantage that the bonding property between the steel wire 101 and the clad member 110 after the first step is increased. As a result, the life of the final clad steel wire 120 manufactured becomes longer, and the final clad steel wire 120 is required to have corrosion resistance according to the present invention.
The clad steel wire 102 after the cladding process 300, that is, the second step, is subjected to a third step (S120) in which the plasma heating process 220 is performed again. The plasma heat treatment process 220 in the third step is performed by the same plasma treatment process as the plasma heat treatment process 210 in the first step. The clad member 110 subjected to the second step is bonded to the steel wire 101 and the plasma heating process 220 at this step is performed after the clad member 110 and the second step Thereby forming a bonding interface of the clad steel wire 102. Bonding property between the clad member 110 and the clad steel wire 102 that has undergone the second step due to the bonding interface by the plasma heating process 220 is increased. In this case, unlike the plasma heating process 210 in the first step, the heating temperature of the clad steel wire 102 after the second step of the plasma heating process 220 in the third step is preferably 500 to 800 ° C. When the heating temperature is 500 캜 or less, the diffusion energy is insufficient and the bonding interface is not smoothly formed, so that the bonding property between the clad member 110 and the clad steel wire 102 after the second step is lowered. In addition, when the heating temperature is 800 ° C or higher, the mechanical properties and the draft characteristics of the final clad steel wire 120 are lowered due to the structure decomposition of the clad steel wire 102 after the second step, and the strength of the final clad steel wire 120 is lowered This shortens the service life of the final clad steel wire 120 and causes a disconnection of the final clad steel wire 120 in the drawing process 500 to be described later. Therefore, the heating temperature of the plasma heating process 220 in the third step is preferably 500 to 800 ° C.
The clad steel wire 103 having undergone the third step S120 is subjected to a fourth step S130 which is a step 400 of hot rolling. Hot rolling is referred to as hot rolling, and refers to rolling a metal material through a rolling roll 401 at a temperature higher than a recrystallization temperature. Generally, in a metal material, when the melting point (absolute temperature) of the metal as a reference exceeds about 1/2 of the melting point, diffusion is actively caused, and therefore, recrystallization starts in the cold working material. Therefore, when hot working (plastic working) is performed at a temperature higher than the temperature at which recrystallization starts, work hardening does not occur, and therefore, there is an advantage that large deformation can be performed by one hot working. Although not shown in the present invention, it is generally preferable to carry out post-finishing by cold rolling after a large pressure is applied by hot rolling in rolling. Therefore, if the clad steel wire 103 having been subjected to the third step in the present invention is subjected to the fourth step (S130) of hot rolling 400 through the rolling roll 401, The bonding property between the clad steel wire 103 and the clad member 110 can be increased and work hardening during the rolling process can be prevented.
When the clad steel wire 103 having undergone the third step is changed to the clad steel wire 104 having passed through the fourth step through the hot rolling step 400, the reduction rate of the sectional area of the clad steel wire 103 after the third step is 5 to 10 %. ≪ / RTI > When the sectional area reduction ratio is 5% or less, the bonding property between the clad member 110 and the clad member 110 after the fourth step is weakened. When the sectional area reduction ratio is 10% or more, the thickness of the clad member 110 is non- The quality problem of the battery 120 occurs. Therefore, the rolling of the clad steel wire 103 after the third step so as to have a reduction ratio of 5 to 10% is in line with the object of extending the life of the final clad steel wire 120 and increasing the corrosion resistance.
The clad steel wire 104 having undergone the fourth step is subjected to a fifth step (S140) of a wire drawing process (500). The drawing process (500) is a kind of metal processing method. When a steel wire or a wire is manufactured, a line is drawn through a hole of a drawing machine (501) to make a desired shape and dimension line. The rod having a proper thickness is drawn out through a piercing drawer 501 in accordance with the cross-sectional shape of the desired line, thereby reducing the thickness and repeating this operation to make the line gradually thinner. According to the present invention, a hole of the drawing machine 501 is prepared so that the final clad steel wire 120 having a desired shape and dimensions can be drawn out. ) Will finally be produced. At this time, it is preferable that the drawing process 500 includes a process of coating the clad steel wire 104 that has undergone the fourth step through a separate machine (not shown). The coating process is to lubricate the material to facilitate the drawing process, and the clad member 110 should be lubricated with a suitable coating. The thickness of the clad member 110 of the final clad steel wire 120 is preferably 50 탆 or more. If the thickness of the clad member 110 is too thin in the drawing process (500), sufficient corrosion resistance can not be ensured and this is not the object of the present invention.
5 is a flowchart showing a method of manufacturing a clad steel wire according to the present invention. Hereinafter, a clad steel wire manufacturing method according to the present invention will be summarized with reference to FIG.
The steel wire 100 is subjected to a first step S100 in which the surface of the steel wire 100 is subjected to the plasma heat treatment 210. At this time, the heating temperature of the plasma heating process 210 is preferably 100 to 200 ° C. The steel wire 101 having been subjected to the first step S100 is subjected to a second step S110 in which the clad member 110 in a strip state is subjected to a cladding process 300. [ At this time, it is preferable that the cladding member 110 is spirally twisted to the center of the steel wire 101 which has been subjected to the first step S100, and the cladding process is performed. The clad steel wire 102 that has undergone the second step S110 is subjected to a third step S120 in which the plasma heating process 220 is performed. At this time, the heating temperature of the plasma heating process 220 is preferably 500 to 800 ° C. The clad steel wire 103 having undergone the third step S120 is subjected to a fourth step S130 of hot rolling 400 through the rolling roll 401. [ At this time, the reduction ratio of the sectional area in the hot rolling 400 is preferably 5 to 10%.
