Latest Patents

Frithum’s patent, “Inline Silicon Deposition in a Pickling Plant,” describes a device and method for depositing undissolved materials, particularly silicon compounds, from pickling fluid. The system uses a flocculation device to introduce one or more flocculants into the main flow of fluid and a deposition device in the circuit tank to settle the undissolved materials. The deposition device may use inclined clarification.

The described pickling circuit includes a pickling tank for treating metal strips, a return line connecting the tank to a circuit tank, a circulation pump, and a heating device in the pressure line between the circuit tank and the pickling tank. For silicon-containing steel strips, the method can use at least two stages of flocculation in two or more mixing-zone containers.
