APPLICATION OFUTsV PLANTS

Circulation fan plant (UTsV 1322, UTsV 2225) creates a circulation of protective gas with a temperature of up to 850 degrees during bright annealing of cold-rolled steel coils in bell-type furnaces, ensures even heating of coils and increases the productivity of bell-type furnaces

Manifold with enclosure

UTsV design

The circulation fan plant consists of the following main units: a fan with a built-in electric motor, a guide vane, a bypass, a set of support rings.

The fan consists of a housing, a shaft supported by the impeller bearings, which is the operating element of the fan and by rotation circulates the protective gas under the muffles of the bell-type furnace.

The fan is cooled with water supplied to the hollow shaft, the housing and the upper flange.

—
The guide vane evenly distributes the gas flow under the muffle and serves as a support for the stack of coils. It consists of a housing, eight links, a top plate, a top ring and a grill.

—
The grill is designed to protect from ingress of foreign objects into the guide vane and on the impeller.

—
The guide vane is installed on the supporting rings. Under them, inside the supporting rings, there is a bypass through which inert gas enters the upper cavity of the fan flange, thus creating a positive pressure and eliminating air suction into the furnace through the shaft seal
