Steel Wire Drawing

Enlargement

• The program solves all the problems connected with the drawing of the steel. With certain variations can be extended to any metal.
  
  The more important characteristics of the program are:
  
  
  • 1.1. Problems that deals with the raw materials, tools and standards.
    
    
    • 1.1.1. It allows (and requires) the construction and modification of files that contains.
      
      
      • :: The standards or catalogues of rod diameters.
      • :: The standards and/or catalogues of complete chemical composition of the rods…
      • :: The mechanical and electrical characteristics of the drawing machines. (Block diameter, type of motors (AC/DC), maximum inlet and minimum outlet diameters, number of drafts…etc).
      • :: The creation of files with standarized series of diameters that reduces the need of dies stocks.
      • :: The file with the variation of strengths versus area reduction for all the type of steels, including microalloyed steels.
        
        
    • 1.1.2. With this information, the program calculates:
      
      
      • The die diameters, necessary power in the motors, speeds, strength in any draft, taking into account:
        
        
        • :: If he machine is AC or DC driven, and the class of lubrication.
        • :: The minimum area reduction per draft.
        • :: The possibility of to obtain different final diameters from an unique inlet diameter.
        • :: If necessary, the program, automatically or manually, reduces:
          
          
          • :: The number of drafts, in the AC motors or in the DC with a determinated speed (if the first motors are run over the maximum speed for every motor).
          • :: The speed in the DC machines if the maximum speed is reached in any motor.
          • :: The drafts may be of constant value, or decreasing in order to obtain constant power consumption in every draft.
            
            
    • 1.1.3. All the results are saved in files and can be listed for every class of product.
      
      
  • 1.2. Problems connected with the final product.
    
    The principal aim is to obtain the most economical fabrication process.
    
    
    • 1.2.1. According with the characteristics, a previous classification is made in the introduction of the programs according with strength, surface and elongation. The aim is the determination of the steel to use.
      
      
    • 1.2.2. The steels considered are:
      
      
      • :: Medium and high carbon steel, with the use of rod without patenting or with patenting.
      • :: Mild carbon steels with rimmed or killed steel and of electric or converter origin.
      • :: Microalloyed steels instead of high C content in certain cases.
        
        
    • 1.2.3. If possible, it’s used the drawing over previously galvanized wire instead of the more expensive final galvanizing.
      
      
    • 1.2.4. For the determination of the process is considered:
      
      
      • :: The available rod and steels.
      • :: The existing machines and the surface coating and heat treatment plants characteristics.
      • :: The required characteristics of the final product.
      • :: The state of the art in the drawing technique.
      • :: The user can select between the possibilities of increase the total section reduction or the C content in the most complicated cases.
      • :: The fabrication process gives the expected medium and extremes strengths.
        
        
  • 1.3. With all this considerations, gives the more convenient fabrication process, that includes:
    
    
    • :: Specifications for the available raw material.(diameter, composition.. etc). Necessary heat treatment (Stelmor, patented, annealed, etc..)
      
      
  • 1.4. The different process are saved classified by surface and standards.
