The key process for setting the material properties comprises mainly water cooling. SMS group has accumulated extensive experience in the development of plate cooling and quenching systems. 

SMS group has further developed the spray-cooling system concept and the conventional roller-type quench and adapted it to the heat treatment process. The progressive development of the mill’s proven, rigid design resulted in the X-Roll^® MultiFlex-Quench. All the features of established plate cooling systems and quenching systems were combined and innovatively planned in advance.
