First, please refer to Figures 1, 2 and 3 for explaining the first embodiment of the method for continuous casting and hot rolling of the metal strip of the present invention. The method according to the present invention comprises at least the following steps: In a linearly arranged workstation, a metal furnace 1 1 for maintaining a supply of molten metal flows a metal melt into a liquid distributor 1 2 via a discharge pipe 111, and the discharge pipe 1 1 1 includes a flow control device 1 1 2 A predetermined flow rate is supplied to the metal melt. The melt distributor 1 2 is provided with a high control device 122 for maintaining the liquid level of the metal melt at a working level. The melt distributor 12 further includes a connecting pipe 121, thereby providing a source of gaseous gas supply (not shown). Providing an inert gas such as nitrogen, the melt distributor 12 is filled with an inert gas atmosphere to insulate the molten metal contact to accelerate oxidation; and the melt distributor 12 further includes a nozzle device 123 having an extended length The outlet 123a is controlled to flow the melt from a side of the outlet 123a thereof at a predetermined flow rate. A pair of roller devices 13 are disposed on the outlet side of the nozzle device 123. The roller device 13 includes an upper roller 13a and a lower roller 13b. The best description is porous. The root metal is melt controlled - liquid; an inert, so that the slurry and the ground metal 123a, which is parallel to the top and bottom of the 201215466, maintain a predetermined roll gap between the two, and is received at the exit of the nozzle device 123 The side of the 123a side and the pair of side fences 123b are closed on the left and right sides of the side of the outlet 123a and compensated between the upper roller 13a and the lower roller 13b for stopping the overflow of the metal melt. The upper roller i3a and the lower roller 13b have an axial circumferential wall and a radial side wall, and define an outer peripheral rolling surface 130 and an inner hollow chamber 131, and a diameter of the upper roller 13a and the lower roller 13b. An inlet 132 for the coolant is provided to the center of the side wall, and an outlet for the coolant (not shown) is provided on each of the opposite sides. Wherein, on the circumferential surface of the upper roller 13a (i.e., the axial circumferential wall surface), a plurality of punches 133 projecting a predetermined height toward the roll gap are formed, and regions other than the punch 133a are formed. The concave surface 133b is recessed to a predetermined depth (as shown in Fig. 2); and the periphery of the convex mold 133a along the upper roller 13a is designed with a slightly inclined draft angle Θ, which is preferably at 1. Between 10° (as shown in Figure 3a). Further, a wedge-shaped guiding device 135 is disposed on the other side of the roller device 13, that is, on the opposite side of the outlet 123a of the nozzle device 123, and the tapered end portion of the guiding device 135 extends toward the rolling surface 130 of the lower roller 13b. The apex of the guiding device 135 has a guiding surface 135a which is about the same height as the rolling surface 130 of the lower roller 13b (as shown in Fig. 3). The pair of upper roller 13a and the lower roller 13b are respectively rotated in opposite directions' and the metal melt Sh is introduced from the outlet of the nozzle device 123 to pass through the light slit; meanwhile, a cooling liquid such as water or the like flows through the upper roller 13 respectively. a and cooling in the chamber 131 inside the lower roller 13b, the cooled rolling surface 201215466 130 causes the molten metal Sh to be semi-cured Sc, and the metal sheet 30 of the porous 30a is extended from the roll gap while rotating. (as shown in Figure 3). The porous metal strip 30' extended from the roll gap of the roller device 13 is guided by the guiding surface 135a of the guiding device 135 to be horizontally advanced and enters a guiding roller set 14, and is biased via a strip. The shifting device 15 corrects the offset of the advancement direction and continues to advance. The perforated metal strip 30 is removed by a chip removing device 16 during the advancement process, and the expanded metal strip 30 is preferably held in an inert protective gas and advanced to the next rolling. Prior to station 18, the perforated metal strip 30 is heated by a temperature compensating device 17 to a set temperature for hot rolling. The heated porous metal sheet strip 30 is advanced to a rolling station 18 for finishing rolling. The rolling station 18 includes a plurality of finishing rolled roller sets 181 which are finished by the roller set 181 to be substantially uniform. The predetermined target thickness 'and has a flat and refined surface and predetermined mechanical material characteristics and the like. The perforated metal strip 30 is cooled by a cooling device 19 after the finish rolling operation. According to the invention, in the ideal case, the distal end of the roller device 13, i.e., the end of the workstation, is provided with a drive device 2 1 to provide traction for the feeding of the perforated metal strip 30, in the embodiment of Fig. i, Preferably, the driving device 21 is disposed in front of the winding device 22 to stably feed the porous metal strip 30, and then the porous metal strip 30 is wound into a coil by a winding device 22; and, at least A cutting device 20 is disposed in a forward position of the driving device 21 for predetermining the length of the steel coil or the like. So, by the above? L-metal strips are continuously cast and hot-rolled to achieve a consistent process and efficient mass production of porous gold 201215466. This not only saves punching waste but also reduces production costs. 4, 5 and 6 are diagrams for explaining the second embodiment of the method for continuous casting and hot rolling forming of the perforated metal strip of the present invention. The upstream process of this embodiment is basically the same as that of the first embodiment, so it is not repeated. Narration. The only difference in this embodiment is that, in the downstream process of FIG. 4, after the porous metal strip 30 is cooled by the cooling device 19, the porous metal strip 30 is divided into a predetermined length by a cutting device 20. The steel sheet 31 and the porous steel sheet 31 are advanced by a feeding device 23 into a punching device 24 having a mold corresponding to the final product of the porous steel sheet workpiece 3 1 ', which is stamped and formed at one time (as shown in Fig. 6) Show). Looking at the method of the present invention, the desired finished product can be obtained without punching, and although the accuracy of the hole in the metal plate is slightly poor, the machining process and the mold cost can be omitted, and the saving can be greatly saved. The punched waste 'further reduces production costs. In contrast, the conventional method of forming a porous metal sheet is to cut the formed metal strip into a predetermined length 'reuse the punching mold and multi-machine machining to obtain the desired finished product' although its metal The accuracy of the hole in the strip is better, but it takes a lot of machining and mold costs, and it takes a lot of punching waste. The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. 201215466 [Simple description of the drawings] Fig. 1 is a flow chart showing the first embodiment of the method for continuous casting and hot rolling forming of the perforated metal strip of the present invention.
