Description

METHOD OF WINDING A STRIP OF MATERIAL The present invention relates to a method of winding a strip of material (e.g. steel) after passing through a guide assembly.
Guide assemblies are used in e.g. a hot rolling line, upstream of a down coiler and downstream of a finishing mill.
A strip of material is guided by the guide assembly to a predetermined position and is passed through pinch rolls to the down coiler where the strip is urged by wrapper rolls to a mandrel disposed horizontally and centrally of the wrapper rolls, around which mandrel the strip is wound.
Figure 1 is a schematic plan view from above of a finishing and winding installation including a known guide assembly; Figure 2 shows a coil produced by a known method.
This guide assembly 6 comprises a pair of guide members 1 at opposite sides of a pass line L, that is to say, a notional line along which a strip of material passes through the installation. Each of the guide members 1 has two air cylinders 2 operatively connected thereto to control the degree of opening and spacing of the guide members 1. The guide members are initially spaced well apart from each other. A sensor 3 on the inlet side of the guide assembly detects the passing of the leading end of a strip and a further sensor 4 on the inlet side of the guide assembly detects the velocity of the strip. The signals from the sensors are fed to an arithmetic unit 5 which calculates the time at which the strip enters the guide assembly. On the entry of the strip, the arithmetic unit signals the cylinders 2 to actuate the air cylinders to narrow the gap to a predetermined distance corresponding to the expected width of the strip. Any substantial change to the position of the guide members to accommodate a change in the width of the strip is carried out by dismantling the assembly by means of screws and nuts (not shown).
Reference numeral 11 denotes a finishing mill, numeral 7 denotes winding apparatus and numeral 8 denotes pinch rolls.
This method has the disadvantage that the movement of the guide members 1 on the strip S entering the guide assembly 6, or on engagement of the strip S with the pinch rolls 8, may result in one side edge of the strip S being out of contact with the respective guide member or may cause uneven contact with the guide members 1, due to deviation of the strip S from the centre line 0. The length of the strokes of the air cylinders also cannot be changed, resulting in poor control.
The final width of the gap between the guide members 1 must be relatively large to accommodate the maximum envisaged width of the strip, which may accordingly cause lateral displacement of the strip, disadvantageously resulting in the development of so-called "telescoping" of the coiled strip which is wound by the machine.
"Telescoping" is a phenomenon whereby part of the coil is displaced laterally with respect to the remainder of the coil.
If the strip deviates from the centre line of the installation, the guide members 1 still guide the strip along the centre line after the strip has engaged with the pinch rolls and the down coiler, so that the strip continues to be gradually deviated. This results in the coil telescoping as well as causing flaws in the strip and wearing of the guide members 1 due to large forces between the guide members and the strip.
If the width of the strip changes after the gap between the guide members has narrowed, ,further problems arise. If the gap is larger than the width of the strip, the coil may telescope, the degree of telescoping depending upon the size of the gap between the strip and the guide members 1. If the gap is smaller than the width of the strip, the strip may be damaged at its side edges and/or may ride over the guide members 1.
Telescoping may occur on the opposite sides of a coil 9 produced by the known method due to variations in width of the strip from the expected widths. As a result, when the coil 9 is laid on a horizontal surface, with its axis vertical, to be transported, the lower side of the coil 9 may be damaged (see Figure 2).
It is an object of the present invention to provide a method of winding a strip of material which substantially avoids the damage which often is incurred by conventionally wound strips during transport.
According to the present invention, a method of winding a strip of material of varying width comprises passing the strip through a guide assembly and varying the position of the centre line of the strip with respect to a mandrel onto which the strip is wound so that a coil is formed having at least one substantially uniformly wound portion in which the side edge of the strip affords a substantially flat surface, which portion extends beyond the remainder of the coil.
Further features and advantages of the invention will be apparent from the following description of specific method in accordance with the invention, which is given by way of example only, with reference to Figures 3 to 5 of the accompanying drawings in which: Figure 3 is a schematic plan view from above showing a finishing and winding installation for performing a method according to the invention; Figures 4 and 5 are transverse sections through coils manufactured using the method in accordance with the invention.
Referring to Figure 3, a machine for performing a method in accordance with the invention comprises a guide assembly 10, disposed on a hot run or transfer table 14 between the downstream side of a finishing mill 11 and a set of pinch rolls 13 upstream of a down coiler 12.
The guide assembly 10 comprises a pair of guide members 15 on opposite sides of a line L along which a strip of material passes, in use (the pass line). Thus the longitudinal centre line of the strip constitutes the pass line L. The guide members 15 can be moved toward or away from the pass line L substantially parallel with it or obliquely to it. In order to drive the guide members 15, two or four hydraulic cylinders 16, each with a sensor for detecting the position of the associated piston rod, are attached to each of the guide members 15 through universal joints or the like. The piston rod of each cylinder 16 is driven to any desired position by working oil supplied to the cylinder 16 through a servo valve (not shown). Strip edge sensors 17 and 18 are disposed on the upstream and/or downstream sides of the guide assembly 10. In response to output signals from the sensors, a control unit 19 delivers control signals to the servo valves for the hydraulic cylinders 16.
In the method of the present invention, the position of the centre line of the strip is changed by means of the guide members 15 during winding, to form coils 30, 40 such as those shown in Figures 4 and 5, respectively.
The coil 30 (Figure 4) serves to overcome certain problems encountered with coils intended to be laid on one side. A flat wound portion 33 is deliberately made to protrude on one side beyond the inner and outer regions of the coils 31, 32, composed of,the leading and trailing ends of the strip 30a, 30b, which are telescoped.
In Figure 4, the flat wound portion 33 protrudes in the opposite direction to the inner and outer regions of the coil. However, it is to be understood that the flat wound portion 33 may be formed to protrude on the same side as the inner and outer regions 31, 32, as long as the flat wound portion 30 extends beyond the inner and outer portions 31 and 32.
The coil 30 can be laid on its flat wound portion, and thus easily transported. Damage to the sides of the coiled strip, particularly at the inner and outer portions which tend to telescope, can be prevented.
The coil 40, shown in Figure 5, may be laid on either side. A protruding flat wound portion 43 is formed on one side of the coil which protrudes beyond the telescoped regions 41 and 42 at the inner and outer portions of the coil, which protrude in the same direction as the flat wound portion 43. The other side of the coil has two separate flat wound portions 44.
The flat wound portion 43 has a protruding height d, whilst the telescoped portions 41 and 42 have a protruding height d/2. The two flat wound portions 44, which define a groove opposite the flat wound portion 43, have a protruding height of d with respect to the bottom of the groove and a protruding height d/2 with respect to the telescoped portions 41, 42.
The coil 40 thus has one flat wound portion 43 on one side thereof and two spaced flat wound portions 44 on the other side. Alternatively, the single flat wound portion 43 may protrude on one side, together with the telescoped portion 41 comprising the leading end 40a of the strip, and a single flat wound portion 44 may protrude on the other side, together with the telescoped portion 42 formed by the trailing end 40b of the strip.
Either of the above coils may be laid down stably with either side facing downwards. Damage to the sides of the coiled strip, particularly at the projecting/ recessed telescoped portions 41, 42 may thus be prevented.
When it is desired to wind the strip into a coil of the type shown in Figures 4 or 5, the spacing of the guide assembly and position of the centre thereof can be calculated depending upon the desired shape of coil, the width of the strip and length of the strip and the position of the leading edge of the strip to be wound.
In response to control signals from the control unit 19, the working oil fed through the servo valves to the hydraulic cylinders 16 is controlled, thereby controlling the centre position of the guide members 15 and the spacing therebetween. In this case, the position of the centre of the strip S is changed by the action of the guide members 15 on the sides of the strip. Displacement of the guide member or members 15 is effected by the two hydraulic cylinders 16 on each member and the servo valves, in response to the output signals from two position sensors.
In determining the position of the guide members 15, information about the position of the actual centre of the strip and width of the strip may be sensed, using the upstream and downstream sensors 17 and 18, and fed back to the control unit 19.
In the above description, it has been stated that one side of a coil is formed with one or two flat wound portions; but it is to be understood that, depending upon the size of the coil, any number of flat wound portions may be formed on either side of the coil.
In order to wind the strip in the form of a coil as shown in Figure 4 or 5, the mandrel of the down coiler may be displaced laterally, rather than the centre of the guide assembly being moved.
