Title: Method and apparatus for automatically controlling the rate of flux injection to a converter
IPC: G05D7/06
Filed: 1976-04-01
Abstract: Flux is injected into the oxygen stream being fed to the tuyeres of a steel-refining converter, such as a Q-BOP converter or the like, and the rate of injection is controlled by varying the size of the outlet orifice of the flux-containing tank. The tank is pressurized to the same pressure as the oxygen stream into which the flux is being injected. The weight of flux in the tank is continuously measured and the actual weight is compared with a preset reference weight for each point in time. The difference between the two weights is used to drive a motor in either the forward or reverse direction to open or close the variable-orifice flux tank outlet valve an amount sufficient to adjust the actual injection rate to match the reference weight for a given time.

Title: Extrusion press for extruding tubes
IPC: B21C23/21
Filed: 1978-01-24
Abstract: In tube extrusion presses, there are two steps in production.
