A key shareholder in Brazilian steelmaker Usinas SiderAorgicas de Minas Gerais SA said on Friday that industry veteran Tulio Chipoletti was named as senior industrial vice president on a temporary basis. Ternium SA, one of the two controlling shareholders in the company known as Usiminas, said Chipoletti's appointment does not preclude it from plans to get JuliA n Eguren reinstated as chief executive officer.
