For the production of rolled metal wire, from which finished metal wires are obtained by subsequent drawing operation, the primary materials used at present are big ingots generally obtained by smelting.
These ingots are then subjected to plastic reduction working by various means such as rolling mills, extrusion presses etc.; but as they must be of restricted length,
the whole working process becomes intermittent with passive times, discarded work, notable employment of labour and heavy and costly machinery and, therefore, affects in a negative sense production cost, quality of products and the possibilities of extending this work to small and medium industries. present invention to provide an improved mechanism by which the molten metal is directly, automatically and continuously transformed into rolled wire without any limits of length as far as molten metal is available.
The mechanism is such that the metal, previously brought to the liquid state, is fed to the improved casting machine of the invention wherein a solid bar is produced continuously which may then be directly trans- Fig.- 2 is a cross-sectional view of oneof the compo-- nents of the machine of Fig. 1.
Figures 3 to 7 show-a form-of a train of special roll-' ing mills aligned for therolling-of the continuous b'ar.
Figs. 8 and 9 represent an embodiment of the complete production process with the. smelting and automatic pumping furnace to feed-the molten metal to the casting machine, which in turn feeds the material to the rolling mill train.
With reference to Fig. 1, the transformation of the molten metal into a continuous solid bar is obtained by means of a rotating drum 1 on the peripheral surface 3 of which there is provided a groove 2, closed by themetal belt 4 along thevarc along which the said belt 4 engages the peripheral face 3 of the rotating drum 1. engages also the wheel'5, which is freely rotatable about the pin 6, the latter being supported by the arm 7. The arm 7 is rotatably mounted on the pin 8 in such a manner as to ensure tension of the belt 4 even if by the action of heating the said belt 4 grows in length. To the rotatable drum 1 there is imparted a slow rotation in the sense of the arrow by means of the motor 9,
which by means of the pulleys 10 and 11 and of the It is an object of the g,
The belt 4, like a common transmission belt belt 12 actuates the speed reduction gear 13, which,
by means of the pinions 14 and 15 and the chain 16,v
imparts to the rotatable drum 1 a suitable speed of rotation.
The upper portion of the peripheral surface 3 of the drum 1 does not contact the belt 4, where there is placed a container 18, supported by the support 17. Container 18 contains at about constant level the molten metal 19, which, by means of the nozzle 20, flows into the cavity 21 formed by the groove 2 and the belt 4, see
Fig. 2.
The container 18 is kept at a suitable temperature by means of, for example, electric resistors 22 arranged in refractory casings. V the bottom of the container 18 and, therefore, free from oxides and slag, flows into the nozzle from which it comes out as a liquid stream 24, the latter being transformed into a solid bar 25 in the cavity that is continuously formed by the groove 2 and the belt 4. This transformation takes place without vortical movements.
or dripping as would cause oxide films to be included inside the bar. It is, therefore, of utmost importance that solidification takes place immediately close to the mouthpiece (outflow) and in a zone where the groove 2 of the drum has only slight inclination, so that the liquid stream 24 may swell to fill the groove confined by the belt, without any whirls, which would prejudice the formation of the cast bar. ture to obtain continuous cast bars of reduced dimensions but of faultless structure. This zone of formation resulted to be defined by the circular sector of the periphery 3 of the drum 1 comprised between 15 and 45 from the vertical, in the sense of motion. I
It has further been found that it is necessary to reduce to a minimum the path of solidification, that is to say the length confined between the cross-section of the bar not yet completely solidified and the one completely liquid. This path constitutes the piece of bar in coursev of formation, in which the linear shrinkage of solidification may produce considerable cracks. To this end, the drum 1 is subjected to vigorous cooling by means of water circulating inside the peripheral ring. Circulating water enters at the hub 26 of the drum 1 and circulates through the hollow spokes 27 and 28 and to t the conduit 29 provided in the rim of the drum 1, where-. from it returns to the hub through the hollow spokes.
30 and 31, to discharge as indicated by the arrow in Fig. 2. r
In Fig. 1 can be seen the solid bar 32 of approximately triangular shape coming out in a continuous way from the drum 1 at the point where engagement of the belt 4 terminates, to enter the rolling mill. At 33 there is shown a wedge-shaped slide pressed against the groove 2 and compelling the bar to leave the cavity where it formed. 34 shows the base of the machine and 35 a conduit which supplies the molten metal to the container 18.
The rolling mill train shown in Figures 3 to 7 is composed of any number of rolling mill units each of which is composed of three rolls converging at 120 in a central rolling axis where the shape of the said rolls determines the rolling area. Fig. 3 shows one of these rolling mills whose rolls 36, 37 and 38 are fitted onto shafts 39, 40 and 41. The shaft 39 is driven from shaft 46 through gearing couple 47 and 48, and shaft 46 is driven from the main driving shaft 42 through pulleys 43, 44 and belt 45. Shaft 39 transmits rotation to the shafts 4t) and 41 by means of the conical couples 49, 50 and 51, 52. Rotation of the driving shaft 42 renders it possible for a metal bar, for example having circular crosssection, to be rolled in the mill according to the curvilinear and equilateral triangle-shape as shown in Fig. 4.
The liquid metal coming from.
This is an essential fea.
Fig. shows the subsequent rolling mill unit of the rolling mill train, which unit engages the bar emerging from the unit shown in Fig. 3, and the bar is reduced again to circular cross-section as in Fig. 6. In the roll ing mill of Fig. 5 the rolls 53, 54 and rotate in planes shifted by with respect to those of the rolling mill of Fig. 3. These rolls 53, 54 and 55 are profiled at their periphery as arcs of a circumference so as to create a circular passage in which the bar coming from the mill of Fig. 3 is engaged and conveniently guided, the said bar being of approximately triangular cross section. As can be seen in Fig. 6, the edges of the triangular bar coming from the rolling mill of Fig. 3 (bar having roll shaping as shown in Fig. 4-) are rolled by the central portion of the rolls of the mill represented in Fig. 5, which rolls are shaped as arcs of a circle as in Fig. 6. Notable reductions are thus obtained with concentric rolling operations, which cause less transversal creeps in the inner cross-sections of the bar in course of plastic transformation. In comparing Figures 3 and 5 with each other it can be clearly seen how the rolls of each rolling mill rotate in planes shifted by 60 with respect to those of the preceding as well as of the subsequent mills. This arrangement is designed to prevent transversal torsions in the bar, which torsions would inevitably occur when rolling in a continuous train with closely positioned passages as in the case of the invention. Fig. 7 shows how a set of such couples of rolling mills (Figures 3 and 5) may be aligned and controlled by one single shaft 59 in order to obtain rolled metal wire with only one operation of multiple passages, taking care to choose speed of rotation of the rolling mill units in proportions increasing in accordance with the elongations of the bar. In Fig. 7 there is shown a rolling mill 56 such as the one of Fig. 3, while 57 is a rolling mill such as the one of Fig. 5 and 58 again one as in Fig. 3 and so on. 59 is the driving shaft, which actuates all the rolling mills of the train through suitable ratios of speed, of course also respecting the right sense of the rolls. Now the induction furnace will be described, which by means of electromagnetic pumping supplies the machine with continuous casting molten metal. In Fig. 8, there can be seen at 60 a low frequency induction furnace for the smelting of metals. of the twin winding type, wherein the melting channels 61, 62 and 63 of the metal produce at the centre 64 electromagnetic pressures known under the name of pinch effect or Northrup pressures, which pressures occur in the molten metal under the action of the electro-magnetic forces produced by the strong electric currents passing through the conducting molten metal in the channels 61, 62, 63 having restricted cross-sections.
These currents inside the molten metal, which occur in any induction furnace, can be utilized in the secondary channel 62 at the point 64, where the flow of the molten metal is upwards. Here there is inserted the refractory pipe 65 along which the liquid metal is forwarded, and made to run into the constant level container 18. This pipe 65 is suitably heated in the portion over the molten metal level, by means of the resistor 66, in order to prevent solidification of the metal. This induction furnace is capable of melting the metal at any temperature and of conveying it automatically to the casting machine. As in the case of the container 18, from which the liquid metal is taken at the bottom, also here the liquid metal comes from the bottom of the furnace and is, therefore, free from slag and oxides. Fig. 9 shows another vertical section of the furnace of a type having immersed resistors, which are well known. Fig. 8 shows clearly how the molten metal of the induction furnace 60 is automatically pumped by the pinch effect along the pipe 65 that feeds it to the container 18, from which it passes onto the drum 1, where it is transformed into a solid bar 32 having triangular cross-section. Bar 32 passes through the guide 67 into the rolling mill 68 wherein it is transformed into round crosssection. This round bar becomes triangular again in passing through the rolling mill 69 wherefrom it passes through the guide 70 to engage the rolling mill 71 wherefrom it comes out with a round cross-section and so on, as there may be provided any number of such rolling mills. At 72 there can be seen the rolled wire emerging continuously, automatically and directly from the liquid metal. At 73 there is shown a heating device, which may be electric for example, to heat the solid bar 32, which in some cases must be brought to suitable temperature before being subjected to plastic transformation.
