,TagSPECI:TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to a guiding arrangement. More particularly, the present invention provides a wire withdrawal arrangement for guiding wire in aluminium wire feeder in steel making furnace.
BACKGROUND AND THE PRIOR ART
Aluminium is used in ladle furnace to kill oxygen (deoxidize) which is present in liquid steel. It is used in two form i.e. bar and wire. The recovery of aluminium in steel is higher in the case of wire than in the case of bar. This is due to the impinging action of the wire into the steel bath forcing aluminium to go below the bath surface thereby directly reacting with the oxygen However in the case of bar, aluminium being light floats on the top thereby reducing its recovery.
Wire is procured in coil form in which wire is coiled from inner lap to outer keeping the coil axis horizontal. This position of coil is called “eye to wall” position. The wire from the coil is to be pulled by a motor gear box at a speed of 150-300 m/min. However at Rourkela steel plant the motor is placed at the top of ladle heating furnace (LHF). Due to logistic problem the coil cannot be placed at the top of LHF near the motor since there is no crane approach to that place .The vertical pulling of wire from horizontally placed coil is not possible without any guiding arrangement. So coil used to be flipped by forklift in the “eye to sky” position and coiling axis is kept vertical. During flipping coil falls on the ground with its own weight, thereby damaging coil cage & lap of coil, leading to jumbling of coil and subsequent wastage. Pulling of wire through wire feeder unit is not smooth and wire gets jumbled between the loops. This leads to low feed rate & 10 -50% (sometimes as high as 80%) of coil remain unused due to jumbling. All of the above factors lead to following problems.
1. Material Loss: Coil cannot be consumed fully thereby reducing its recovery. This leads to higher consumption of Aluminium.
2. Process Delay: Coil needs to be replaced frequently as it is not consumed fully.
3. Housekeeping & Safety: Keeping jumbled wire in shop floor leads to improper housekeeping & unsafe working conditions.
Therefore to overcome the problems in conventional arrangement for pulling the wire, the present invention provides a guiding arrangement for wire withdrawal from the coil and guiding the wire in aluminium wire feeder, thus reducing the jumbling up of the coil and therefore reducing the aluminium consumption and providing a controlled feed rate of wire.

The figure 2 and 6 provides different view of the present disclosed wire withdrawal arrangement which includes a base plate, a ring assembly and a guide roll assembly.
In fig 3, a base plate (1) of 20 mm thick over which the guide ring (2) and roll assembly (3) is supported is also used to place coil over it. Four numbers of rings of different diameter joined together and placed bigger to smaller diameter in feeding direction as shown in figure 4. The function of the ring assembly (2) is to take wire from coil and feed concentrically to guide rolls (3). The guide roll assembly (3) consists of 5 numbers of 130 diameter free roll supported by plates at both side shown in figure 5. Side plate supports the roll as well as provides required passage for wire. Jacking arrangement is done to adjust passage opening for different diameter of wire shown in figure 6. The ring and roll assembly is placed at 45 degree angle to the axis of coil so that wire from horizontally placed coil smoothly changes its direction to vertical, gliding between the rolls shown in figure 2 and 6.
Advantages
A) By this arrangement coil is used to last extent (sometimes max 10% is left over).Drastic reduction of coil replacement due to increased utilization and reduction of wastage on account of reduction in jumbling of coil. Housekeeping & safety aspects are ensured. Cost of aluminium coils is approximately Rs 1, 50,000. Any reduction in Aluminium consumption helps in improving the bottom-line of the company.
A look at the aluminium consumption pattern shows the efficacy of the wire feeder guide as shown in fig. 7.
B) Load on wire feeding unit was drastically reduced, breakdown on account of motor/gear box had been completely eliminated.
C) Coil changing time had been reduced, availability of LHF enhanced & feed rate of wire kept under control. Similar usage of guide can be adopted in other steel industries using the wire guidance system.
D) The basic concept of using the coil in its designed position (as supplied by the supplier) and extraction of the coil from its center helps in smooth unwinding of coil thereby reducing the jumbling up of the coil.
