Mainstrip

Mainstrip is a new steel strip casting technology for strip production of 0.5—4mm and a width of up to 1700mm, based on the twin roll process.

Mainly

  • for ministeel  mills, interested to produce 0,5—1 Mio t/year of steel strip
  • for  Integrated mills for surplus steel and special strip grades

With particular advantages on

  • compactness of installation and small space requirements
  • low investment costs
  • compact operating team
  • reduced maintenance- and spare parts costs
  • substantial lower power requirement, down to 10%
  • substantial lower CO2 exposure, below 10%

To produce best quality of

  • carbon grades
  • alloyed grades
  • stainless steel grades 
  • new twip- and trip qualities

Local Markets

  • operating close to local markets and to diversify to the strip side, avoiding long and expensive transportation of scrap and coils to serve customers within hours to their particular needs and request.

Available to be purchased

Mainstrip is available to be taken over by investors, steel mills or groups, already active in this field. It is for works with the intention to become active on twin roll casting, or machine builders or institutes, interested to play an important role, in this coming market.

In each case a cooperation or support of Main, with the respective specialist can be secured.
