Long Product Minimills

Minimills

Tailor-made solutions for more customer value

Minimills are part of our DNA. We pioneered the idea of an integrated plant consisting of an electric-arc furnace and associated rolling mill - and turned it into reality. Today, SMS minimills consistently deliver the highest performance and shortest downtimes. You'll always receive innovative, integrated automation solutions designed to boost productivity and reduce your manpower. All this ensures you reap a fast return on investment.

CMT^® Technology

Direct link between caster and rolling mill

Our CMT^® technology eliminates the need for handling and reheating by linking the caster to the mill. An induction heater gives you perfect control of the starting temperature for the rolling mill - according to the billet speed. Using CMT^® technology means no foundation works in the furnace area and no billet storage are necessary. Environmental aspects demonstrated by the Tung Ho reference plant:

Savings of 72,000 tpy of CO2 emissions (greenhouse effect)
Savings of 410 tpy of SO₂ emissions (acid rain)
Savings of 225 tpy of NOx emissions (acid rain)

Induction heater key data

Induction heating system for re-heating and axial equalization of
billets from CCM to RM
0.07 to 1 m/s speed range
Perfect temperature control in combination with billet speed
Top rolling performance and operating flexibility
