<\/p>\n

The Calibration process is defined as a process for deforming a metal bar with the aim of reducing its cross section.<\/h2>\n

This process can be carried out in various forms by drawing<\/strong> or multi-pass drawing<\/strong>. Nueva Incal transforms steel by cold<\/strong> drawing<\/strong>, consisting of reducing the cross-section of a piece using a die made from a very hard material inserted in a steel block. This reduction depends on the opening in the die.<\/p>\n

The main advantages of the drawing process compared to multi-pass drawing are:<\/p>\n

    \n
  • Greater control over tolerances<\/strong>.<\/li>\n
  • Better surface finish<\/strong>.<\/li>\n
  • Mechanical properties<\/strong>: greater bending strength and higher hardness. Improved machinability.<\/li>\n<\/ul>\n

    A descaling<\/strong> or cleaning process is performed before the drawing process to remove possible oxides, rolling scale, etc. At Nueva Incal, the descaling process is carried out by shot blasting<\/strong> the surface of the bars, using balls made of hard material.<\/p>\n

    Lubricants need to be used to facilitate the drawing process and avoid damaging the material surface when reducing its cross section.<\/p>\n

    Once the material has been drawn, it is straightened<\/strong>. The material may need heat treatment to improve its mechanical properties.<\/p>\n
