INDUSTRIAL STEAM GENERATOR FOR APPLICATION OF COATING OUT OF ALLOY ON METAL TAPE Russian patent published in 2011 - IPC C23C14/24 C23C14/16 C23C14/56 

FIELD: metallurgy.

SUBSTANCE: steam generator consists of vacuum chamber (6) in form of cavity. A head for steam settling in form of ejector (3) is placed into the cavity. The head is pressure tightly communicated with at least one crucible (1) by means of supplying pipeline (4). The crucible, containing liquid metal for coating is positioned outside vacuum chamber (6). Ejector (3) has a lengthwise slit for release of steam, the slit functions as a sound nozzle and passes along whole width of substrate (7). Filtering medium or throttle device (3A) of sintered material is arranged in the ejector directly before the said slit downstream vapours. The throttle device facilitates uniform rate of vapours release from ejector (3) via the sound nozzle.

EFFECT: coating of high corrosion resistance at maintaining optimal characteristics of ability to punching and weldability.
