Definitions

  • the present invention relates to a marking method for collecting, tracking and storing data of a molten metal during melting and casting processes.
  • Metal materials are frequently used in both industrial applications and consumer products due to their durability and longevity. After the metal materials are obtained as a raw material, they are processed by various applications to take a desired shape and size. According to the prior art, different applications are provided for giving the desired shape to a metal raw material. These applications are basically divided into two groups as forging (cold or hot) and casting. In forging applications, the raw material takes the desired shape by delivering blows. In casting applications, on the other hand, the raw material is melted and poured into molds such that when it cools in the mold to solidify, it takes the shape of the mold. The mentioned applications can be used in accordance with the needs based on the desired product properties.
  • Various process parameters are used to give the desired shape to the metal.
  • parameters such as ratios and purity of the alloy components, or parameters such as temperature, environmental conditions or equipment of the casting or forging process, are used.
  • Such parameters can affect different properties of the final product. For this reason, it is important to collect and store the data of said parameters.
  • Said data can be stored by engraving a visual code (such as a barcode, a serial number) on the metal material, especially in forging applications.
  • a visual code such as a barcode, a serial number
  • the metal material is melted, even if a code is added to the raw material, said code disappears during the melting process.
  • patent documents no. WO2018101061A1 , US2018036928A1 , JP2019217506A , EP3378583A1 and US6779583B1 disclose assigning different codes for different production stages for the molten metal. Said codes are stored with production data. However, in said documents, using multiple codes makes said systems complex, which may lead errors. Furthermore, in those documents, only the production data is stored. Therefore, it is not possible to determine possible problems caused by the condition of the used metal (for example storing conditions of the used metals).
  • the present invention discloses a marking method for collecting, tracking and storing data of a molten metal during melting and casting processes.
  • Said marking method comprises the steps of: receiving at least one piece of metal to be melted; storing at least one information of the received metal ingot in a memory unit, wherein information of the piece of metal comprises the type of the piece of metal, total weight thereof, a temperature and a humidity value of the environment where the piece of metal is present;
  • An object of the present invention is to provide a marking method for collecting, tracking and storing data of a molten metal during melting and casting processes.
  • Another object of the present invention is to provide a practical and reliable marking method.
  • the present invention provides a marking method for collecting, tracking and storing data of a molten metal during melting and casting processes.
  • the marking method comprises the steps of: receiving at least one piece of metal to be melted; storing at least one information of the received metal ingot in a memory unit; wherein information of the piece of metal comprises the type of the piece of metal, total weight thereof, a temperature and a humidity value of the environment where the piece of metal is present; melting said piece of metal; assigning at least one pseudo code to the melted piece of metal; storing the pseudo code assigned to the molten metal in the memory unit; molding the melted piece of metal; storing at least one data related to the molten metal and/or environmental conditions during the melting and/or molding processes in the memory unit; assigning a visual code (e.g. a barcode, a serial number) to the final demolded product; matching the visual code assigned to the final product with the pseudo code stored in the memory unit.
  • a visual code e.g. a barcode, a serial number
  • a piece of metal for example, a metal ingot
  • various information about this piece of metal is stored in a memory unit.
  • information of the piece of metal includes at least one of the information such as the type of the piece of metal (such as aluminum, iron, copper, chromium), total weight thereof, a temperature or a humidity value of the environment where the piece of metal is present.
  • the metal obtained is then melted.
  • various data regarding the melting process such as melting temperature, melting period, properties of a melting furnace, are also stored in the memory unit.
  • a pseudo code is assigned to the molten metal, such that said pseudo code is stored in the memory unit together with other data.
  • casting for example, a low-pressure casting
  • different process parameters for the casting process are stored in the memory, as well as in the melting process.
  • Parameters in the casting process may include temperature of a chamber, temperature of a die system, temperature of the molten metal in the chamber, temperature of a coolant (e.g. air/liquid temperature in air/liquid cooled cooler), pressure of the coolant (e.g. air/liquid pressure in air/liquid cooled cooler), flow rate of the coolant, ambient temperature, ambient humidity, ground vibration, tooling vibration, etc.
  • a coolant e.g. air/liquid temperature in air/liquid cooled cooler
  • pressure of the coolant e.g. air/liquid pressure in air/liquid cooled cooler
  • flow rate of the coolant ambient temperature, ambient humidity, ground vibration, tooling vibration, etc.
  • said marking method comprises the step of detecting at least one data of a melting and/or casting process by at least one sensor during the related process. Therefore, in the step of storing at least one data of the molten metal and/or environmental conditions during the melting and/or molding processes, data to be stored in the memory unit is obtained in a practical and reliable manner.
  • said marking method comprises the step of engraving the visual code assigned to the final product on the product.
  • said engraving step can be performed, for example, by printing a shape (such as a QR code or barcode in bar form) and/or an alpha-numeric inscription on a surface of the product.
  • the marking method comprises the step of gluing the visual code assigned to the final product on the product.
  • said marking method comprises the step of sending the data stored in the memory (information on the piece of metal, data on the melting/casting process, visual code matched with the pseudo code) to a remote server.
  • said remote server is preferably a cloud server.
  • the end user can access the information about the production of the product by inputting the visual code information into the cloud server.
