Resumo
To meet the current demand of steel manufacturers for high reduction mill capability for high strength steel and thinner strip production, improved strip crown and shape control capability for various strip grades including silicon steel, easy maintenance and stable operation for high productivity, Mitsubishi-Hitachi Metal Machinery Inc., (MH) has developed unique technologies. One of the most modern mills operating in Brazil is the No.2 Hot Strip Mill at Usiminas Cubatao. MH supplied some of the advanced technologies for this Hot Strip Mill. One of the advanced technologies applied at the Usiminas No.2 Hot Strip Mill is the advanced pair cross mill. The number of parts in the advanced pair cross mill mechanism has been reduced to less than 25% of those of the 1st generation pair cross mills. In addition, a mill stabilizer system is combined with the pair cross mill to reduce mill vibration. The mill stabilizer device improves high reduction rolling and also contributes to stable threading and easy maintenance of the housing window. In this paper, MH introduces the newest high performance Hot Strip Mill.
