Metallurgical industry is a high energy consuming industry. Numbers of high-power motors working under fixed speed waste a lot of Power. Using VFD can solve the soft start problems, save the energy and improve the process.

Blower is the most powerful load in the whole blast furnace system, and its power consumption is huge. At present, many of them use the water resistance cabinet to start and the damper to adjust the operation, and the energy waste is very serious. In the traditional starting mode, other high-power loads must be shut down before starting to ensure that the grid capacity can withstand the starting surge current. Due to continuous expansion of the steel mill blast furnace, the reserves of the grid incoming is limited, so the starting inrush current must be within a reasonable range.
