Description

Aluminum wire feeder

The present invention relates to an aluminum wire supply device for adjusting the aluminum component of molten steel, and more particularly, the operation of the detection unit for detecting the entry and withdrawal of the aluminum wire is made smoothly, and the maintenance of the failure of the part The present invention relates to an aluminum wire supply device which can be easily repaired to improve facility utilization.

In general, a device which is capable of continuously supplying aluminum in the form of a wire into the molten steel to adjust the aluminum (Al) component of the molten steel is schematically illustrated in FIG. 1, which is illustrated in the ladle 110 containing the molten steel 112. The elevator unit 120 is installed at an upper side of the roof 114 to move the elevator 122 up and down, and the elevator 122 is an elevator unit 120 such as a wire rope 126 connected to the motor 124 or the like. It can be moved up and down along the support frame 128 of the second guide tube 140 is mounted so that if necessary, the lower end of the second guide tube 140, appropriate length of the molten steel 112 of the ladle 110 ) And the aluminum wire 130 is supplied to the molten steel 112 through the second guide tube 140, and the upper end of the second guide tube 140 is raised and lowered. Of the wire feeder detector 150 Separated from the outlet side or connected to the outlet side of the detector 150, the aluminum wire 130 passing through the wire feeder detector 150 can be supplied to the second guide tube 140, the wire detector ( The inlet side of the 150 is connected to the wire transfer unit 180 via the first guide tube 170, the wire transfer unit 180 has a plurality of rotary rolls 182 therein to rotate by the motor 184 While being able to convey the aluminum wire 130, the aluminum wire 130 is supplied to the wire transfer unit 180 is wound around a plurality of rotatable wire reel 190.

As shown in detail in FIG. 2, the wire detection unit 150 includes a housing 152 configured to include components for wire detection, and one end of the wire 152 rotates through the pin 153. The pivot member 154 is mounted to be rotatable and the other end of the pivot member 154 is rotatably mounted so as to press the aluminum wire 130 at a proper pressure to be brought into contact with the pivot member 154. Pressing roll 156 to be idling, the coil spring type elastic member 158 to provide a pressing force for pressing the wire 130 by the pressing roll 156 of the pivot member 154, and the pivot member The cam-type detection sensor 160 and the aluminum wire 130, which are mounted on the rotation path of the protruding bar 155 protruding from one side of the 154 and operated by the protruding bar 155, are moved. The lower end of the pressing roll 156 is inserted into the egg Service minyum wire hole (not shown) to make contact with 130 and is made into the guide tube 162 is fixed to the housing 152.

As a result, when the aluminum wire 130 passes through the first guide tube 170 from the wire reel 190 by the rotation of the rotary roll 182 by the motor 184, the wire 130 is connected to the wire detector 150. As the protruding bar 155 is raised by rotating the pivot member 154 equipped with the pressure roll 156 in the counterclockwise direction while passing through the inner guide tube 162 of the detection sensor 160 to transfer the wire 130. In addition, the second guide tube 140 mounted on the elevator 122 as the elevator 122 descends along the frame 128 by driving the motor 124 of the elevator unit 120, the wire detection unit ( Since the state is located at the exit side of 150, the wire 130 can be supplied to the molten steel 112 through the second guide tube 140.

Therefore, by supplying an appropriate amount of aluminum to the molten steel 112 to adjust the aluminum composition of the molten steel component to play a role as a major facility for determining the quality of the steel in the steelmaking process to produce high-quality steel.

By the way, in such a conventional aluminum feeding device, when the detection of the wire supplied to the molten steel side passes by a predetermined time due to the continuous aluminum feeding by the elastic member, the pressure roll 156 of the turning member 154 has an appropriate force. The elastic member 158 to pressurize the wire 130 is relaxed, which causes a problem that the wire 130 is not in contact with the wire 130. Therefore, the transfer state of the wire 130 is not properly detected by the detection sensor 160. In addition, the pressure roll 156 is made of a conventional roll having the same outer diameter to generate a relative slip between the wire 130 and the wire roll 130 to generate uneven wear on the pressure roll 156 to rotate the turning member 154 to an appropriate degree. If not, the protrusion bar 155 integrally fixed to the pivot member 154 may not properly push the contact 164 of the detection sensor 160, in this case The sensor operating rod 166 integrally fixed to the contactor 164 does not rotate the cam 168 to the whole state, whereby the detection sensor 160 to operate by the rotation of the cam 168 is It will not work properly. This makes it impossible to put the appropriate aluminum wire 130, causing a fatal problem of reducing the quality of the molten steel. In addition, since the detection sensor 160 has a built-in structure, the operation of the detection sensor 160 is also very difficult to check, which is undesirable in terms of maintenance.

In addition, the inner guide tube 162 is made of a structure that is fixed by welding, such as the housing 152, in the case of wear and the like to be repaired and replaced, it is possible to dismantle the entire structure, which is to rest the equipment There was also a problem that causes a decrease in productivity.

The present invention was devised to solve the conventional problems as described above, and guides the molten steel component adjustment aluminum wire more stably so that it can be properly introduced into the molten steel, and reduces the occurrence of failures, making maintenance easier and more effective. It is an object of the present invention to provide an aluminum wire feeder.
