Description
The present invention relates to a metal nozzle for producing a metal plate material with a built-in heating means, and more particularly, in the production of a metal plate material by extruding a molten metal melted at a high temperature through a metal nozzle. It is built by installing a heat insulating means on the outer surface of the metal nozzle body and by supplying power to the heating means to generate heat, so that the metal nozzle body to maintain a temperature above a certain value, so that the hot metal melt The present invention relates to a metal nozzle for producing a metal sheet having a heating means for preventing solidification and sticking of the molten metal generated by contact with the metal nozzle.
In general, in order to produce a thin sheet metal sheet by dissolving metal, it is a nozzle apparatus for continuously extruding and scanning a certain thickness of metal sheet material by supplying a melting furnace and a metal molten metal which are largely dissolved into a high-temperature liquid metal molten metal from the melting furnace. The metal plate manufacturing apparatus which is comprised is used. Usually, in the apparatus for producing a metal sheet, a nozzle apparatus made of a metal having a very high melting point is used. The high temperature metal sheet produced by the metal sheet manufacturing apparatus is subjected to a post-treatment process such as rolling cooling or injecting into a mold to have a predetermined shape.
However, such a metal plate manufacturing apparatus using the metal nozzle is a high temperature molten metal melted in the melting furnace passes through the low temperature metal nozzle rapidly cooled and solidified, resulting in a decrease in fluidity causing continuous extrusion injection problem In addition, there is a problem in that the surface quality of the metal sheet produced by being partially stuck to the metal nozzle at all, and there is a hassle to disassemble and maintain the metal nozzle from time to time to remove the impurities stuck in the metal nozzle.
In order to solve the above problems, a means for heating the metal nozzle using a gas torch is used so that the metal nozzle has a temperature higher than a predetermined value, but the heating means using the gas torch has a gas injection device and an ignition device outside the metal nozzle. It takes a lot of cost and space by installing a separate device, etc. Also, the heating means is located on the upper or lower part of the metal nozzle to heat only one part of the upper and lower parts, thereby maintaining the entire metal nozzle at a constant temperature. there was.
In addition to the metal nozzle heating means using the gas torch as described above, a means for heating the metal nozzle using a high frequency current is also used. In other words, the coil is wound around the outside of the metal nozzle, and a separate high frequency current generator is mounted so that a high frequency current flows in the coil to react with the magnetic metal nozzle to generate heat. However, the metal nozzle heating means using the high frequency current can be expected to be effective only when the metal nozzle itself has ferromagnetic properties, so there is no limit to the material of the metal nozzle that can be used, and the thickness of the coil for the high frequency coil is very thick. Since the coil could not be wound tightly over the whole, heat transfer to the metal nozzle was difficult and there was a problem in that the entire portion of the metal nozzle could not be evenly heated.
