ABSTRACT:
A powderized material supply system comprises a plurality of reservoir tanks, each containing a different type of powder, and is associated with a metering means for metering the material into an individual supply line. Each individual supply line is associated with a carrier fluid source which supplies, carrier fluid at a controlled pressure for transferring the metered material with the carrier fluid. The individual material suppply lines, each associated with the corresponding reservoir tank, are connected to a post-mixing chamber into which the metered materials are introduced. The post-mixing chamber is connected to a mixture supply line. Each metering means can be controlled for metering a controlled amount of the material in its associated reservoir tank, independently of others. The powderized material supply system is applicable in various industrial or laboratory level processes which require supply of a plurality of powder state fluid material at a variable rate. The system is specifically applicable for flux injection in hot metal pre-treatment process in smelting process of metal industries. For example, the system is applicable for sequential operation or simultaneous operation for desiliconization, dephosphorization and/or desulfurization during hot metal pre-treatment.
