Core enveloped wire guard wire guiding mechanism

Abstract

A wire protecting and guiding mechanism for the RE or alloy cored wire which is quickly feeding in steel ladle is composed of installing supporter frame, two guide rollers installed to said supporter frame, and one wire supporting roller with a pressing spring under it and arranged between said guide rollers. It can prevent the wire from being broken off and the powder from leaking.

Description

technical field [0001] The invention relates to a core-spun wire that can guide the rare earth element cored wire or alloy cored wire during high-speed wire feeding, and prevent the alloy cored wire and rare earth element cored wire from derailing accidents during high-speed wire feeding Wire guide wire protection mechanism. Background technique [0002] At present, in the process of steelmaking production in steel mills, when the wire feeder feeds the wire into the molten steel at a temperature of about 1600°C in the ladle for refining at a speed of 1 m / s-6 m / s, sudden wire breakage, powder leakage, Faults such as blockage of the feeding conduit. When working normally, you must first start the motor to reach the set speed, and then press down the cylinder so that the driven wheel and the driving wheel are pressed against the rare earth element cored wire. The wire feeder starts to feed the wire into the ladle. Lift the cylinder so that the driven wheel is separated from t...

Problems solved by technology

[0002] At present, in the process of steelmaking production in steel mills, when the wire feeder feeds the wire into the molten steel at a temperature of about 1600°C in the ladle for refining at a speed of 1 m / s-6 m / s, sudden wire breakage, powder leakage, Faults such as blockage of the feeding catheter

When working normally, you must first start the motor to reach the set speed, and then press down the cylinder so that the driven wheel and the driving wheel are pressed against the rare earth element cored wire. The wire feeder starts to feed the wire into the ladle. Lift the cylinder so that the driven wheel is separated from the cored wire and stop feeding the wire to ensure the accuracy. Because the motor starts first, it is inevitable that the driving wheel with sharp teeth will scratch the rare earth element cored wire. At the end of the wire feeding, due to inertia, the driving wheel It will scratch it again, which leaves hidden dangers for broken wires and powder leakage. In addition, the rare earth element cored wire is pulled out forcefully and quickly from the inner tap type coil. Although deformation has occurred, the internal stress has not been eliminated. When feeding the wire, encountering resistance when passing through the bend of the wire feeding catheter, the wire feeding catheter is blocked between the three sets of driving wheels in the wire feeding machine and between the front and rear driving wheels and the catheter, and the machine is off the track and blocked.
