Abstract: In the production of electrical steel strips, a special islab-reheating treatment before hot rolling is carried out so that the maximum temperature within the furnace is reached by the slab well before its extraction from the furnace. During the heating stage and performance at the highest temperatures of the thermal cycle, second phase particles are dissolved and segregated elements are distributed in the metallic matrix, while during cooling and temperature equalising steps of the slab in the furnace a controlled amount of small second phases particles are more homogeneously re-precipitated from the metallic matrix. Differently from all the conventional processes for the production of electrical steels, the slab reheating furnace become a site in which it is performed the precipitation of a controlled amount of second phases particles for the necessary grain growth control during the successive process steps.

Laser beams are divided into a large number of beams by DOE or the like. A work (an object) is irradiated therewith.  <P>SOLUTION: An aperture mask having an aperture of the dimension larger than the beam dimension is provided at the focal position of a homogenizer DOE, and noise portions outside the beams are blocked. So as to prevent a part of beams from being cut, an aperture mask of the size larger windows than the beam size is used so that the beams do not touch the windows.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
