In this formulation, when a two-speed model is usedįor simultaneous calculation of the channel and the tuyere, the problem remains to be adequately solved. Than for downward motion the pressure must be For example, when a gas suspension flows in a metal sleeve of the same diameterĪnd length, the drag will be greater for upward motion The final results-in particular, the parameters of the Horizontal (ascending or descending flow) also affects In addition, in contrast to pure-gas flow (without powder), the inclination of the pneumatic line to the The parameters of the outgoing jetĭepend more on the geometry and drag of the complexĬhannel than on the profile and dimensions of the nozzle itself. Terms, a single unit for powder supply, including a tuyere and a nozzle. As we know, a pneumatic transport system is, in physical and structural Include the separate calculation of the nozzles or pneumatic channels, most often using a model of singlespeed gas-suspension flow. There are no reliable methods of calculating the components of the gas–powder tuyere. Ladle modification of steel, jet guniting, and slag injection by gas–powder jets in converters. The blast furnace, deep desulfurization of hot metal, Powders are widely used in ferrous metallurgy,Įspecially for processes such as coal-dust injection in Priazovsk State Technical University, Ukraine OAO Zapadno-Sibirskii Metallurgicheskii Kombinat, Russiaĭneprodzerzhinsk State Technical University, Ukraine Siberian State Industrial University, Russia Powder Injection into Slag in a ConverterĮ.
