Product Description

• Brand Name: HENGZHONG
• Introduce
  We manufacture the forged steel for cold rolling equipment. Cold rolling is a forming process which takes place below
  recrystallization temperature. It involves further reduction of already hot-rolled strip and a determining of the mechanical and technological properties of the same strip. Due to specific requirements during processing, cold rolling is regarded as a speciality within the diverse application areas of cold-work tool steels. They nevertheless have uses in other fields such as back-up rolls, straightening and section-bending rolls.
  
  Application
  These materials are used in large machinery in the cold forming of steel, such as cold rolled strip rollers, cold rolled profile
  rollers, welded tube forming rollers, etc.
  
  The main steps in roll production are:
  *Melting, refining, ESR
  *Forging
  *Heat treatment in one or several steps
  *Machining
  *Final control
  
  Size
  *Max Diameter: 400-1000mm
  *Max Length: 6000-14000mm

  The mastering of many technologies
  At the heart of our products lies excellence in metallurgy expertise, enabling us to develop new grades and assure the manufacture of high quality rolls.
  We also require specialist skills from other disciplines, such as machining. Application knowledge, such as rolling and roll
  maintenance, are also important competencies for the R&D process, as well as providing technical assistance to our customers.
  
  Roll making
  Manufacturing rolls requires many different technologies, some that we have developed ourselves, and others that are already available in the marketplace. Our foundries, steel plant, forging, machine, and heat treatment shops, are capable of manufacturing a wide range of rolls. Benchmarking between our plants enables us to establish best practices and ensures that knowledge exchange is efficiently spread throughout the company.
  When you consider the challenging environments in which our products are used, the materials and methods that we employ to make our rolls are under high pressure to perform. Add to this the output capacities of today’s high-performance mills, and the fact that operators demand extended roll lifetimes with no degradation in quality, you will see that our task is not an easy one.
  
  Research and Development
  our R&D process also includes evaluation on material properties, validation of process and product qualities, in service
  performance evaluation and follow-up throughout the life span of the product to ensure product quality. The R&D process is based upon a set of predetermined phases which make certain that we can reliably move a new product from design and prototype phases into market launch.
