Device for improving visual appearance of ventilation grills of chimney in industry, has strontium based anisotropic ferrite magnets, and metal plate hollowed to ensure output of closed hearth while forming aesthetic patterns

摘要

The device has strontium based anisotropic ferrite magnets of axial polarity, and a metal plate hollowed to ensure output of closed hearth while forming aesthetic patterns. Magnetization system positions ventilation grills on an upper part of the device by using the ferrite magnets. A decorative grill made of steel is shaped by an oxy-cutting system, and receives powder coated finish paint according to given color. The magnets possess 6 mm dimension.
