MILLSTAND ROLLS

  • The forging division of AST continues the century-long tradition of forging in Terni started in 1884 when the company “Societa degli Alti Forni, Fonderie e Acciaierie di Terni” (SAFFAT) was founded
  • The choice of carbon and alloy elements utilized in the production of Back-up Rolls and Hot working Rolls for flat and shapred products aims to achieve the required mix of different properties, such as hardenability, hardness, toughness, fatigue and thermal cracking resistance
  • All machining steps are performed by using modern Numericla Control Lathes. Rolls are shipped by forging division of Acciai Speciali Terni machine finished and ready for service
  • Sdf quality system was one of the first Italian QA systems to be accepted by ASME for the manufacture of forged products for nuclear application
  • AFS has two main product lines, Static cast and Spin cast
  • In January 2014, Advanced Foundry Services SAS took over from Åkers Group which had been running it since 1998.
  • The company specializes in the manufacture of rolling mill rolls with technical expertise and a quality standards recognized by it’s customer base.
  • AFS is in control of the complete manufacturing process: Melting, Molding, Casting, Shot blasting, Heat treatment and Machining.

  • Trumpets -used when manufacturing bottom pouring steel ingots.
  • Slag Pots – manufactured in lamellar or nodular cast iron.
  • Ingot moulds and base plates -produce high quality steel ingot moulds thanks to more than 20 years of experience
  • Dryer rolls – hollow rolls are used in many industries such as : Paper industry, Food industry, Rubber industry and Plastic industry
  • Shells – cast iron moulds used for roll production
  • Staves coolers – utilized on blast furnace cooling system

Strict quality control checks are adhered to throughout entire process: •

  • Molding: Sand characteristics, raw materials and mould lining controls.
  • Melting: Temperature, weight, chemical analysis and thermal analysis.
  • Casting: Spin casting machine speed, temperatures, weight and filling rate
  • Heat treatment : Temperatures, hardness and structure controls.
  • Internal quality : Bonding, thickness and core health controls.
  • Metal structure : Barrel, core and bonding quality controls.
  • Hardness : Core and barrel hardness controls.
  • Geometric control: drawing review
