The invention relates to a tracking method aiming at single axis solar energy and provides a solar energy tracking method with umbra versa tracking. The solar energy tracking method with the umbra versa tracking accurately calculates positions of the Sun based on modern astronomical algorithms, calculates shadow length of solar panel assemblies and adjusts angles of the solar panel assemblies according to the width of the assemblies and distance between the front and back rows of the solar panel assemblies. Therefore, at any time no shadow can be generated along the east-and-west directions of the front and back rows of the solar panel assemblies, the effects that the sun light is perpendicular to the solar panel assemblies and the light intensity is maximized are achieved, and the photovoltaic conversion rate is increased. The solar energy tracking method with the umbra versa tracking is small in energy consumption, applicable to various latitudes, free from the restraint of the geographical location, capable of being directed at the Sun to the maximum extent and receiving direct solar radiation and capable of effectively avoiding that the east and west assemblies are shaded by the shadow. The technical problems existing in the prior art that the solar panel assemblies shade each other and form the shadows, the sun light receiving is affected, and thereby the photovoltaic conversion rate is affected are solved.

In the production of grain oriented electrical steel sheet, controlling the condition of thin slab continuous casting results in advantageous solidification structures and precipitates. The steel has an initial content of carbon less than 300 ppm and an initial content of acid-soluble aluminum higher than that normally used for said type of steel. During the final processing steps, the annealed sheet is nitrided through a limited amount of nitrogen. This, in turn, renders the process for controlling the grain dimensions much less critical and results in a constant quality product.
