CONTINUOUS FLAT-ROLLED STEEL STRIP CLEANSING AND FINISHING OPERATIONS |
摘要 |
<p>The continuous steel strip cleansing system includes a special separation means (70) for separation, removal and retention of the iron fines and associated debris. In the flat-rolled steel continuous-strip cleansing embodiment, contaminated surface areas of strip (72) are treated, generally by at least partial submersion, in a main tank (73) having sufficient capacity to provide desired travel through a hot caustic solution. Cleaning solution with accompanying contaminants is preferably withdrawn continuously from a preselected location, or locations, and directed through a conduit, such as (76). Monitoring of iron fines in the main tank (73) is schematically indicated at (77). A continuously-operable mechanical filtering structure (78) is preferably selected to provide for withdrawal of a portion of the capacity of main tank (73) at a controlled rate. Filtrate, from which iron fines and associated debris have been mechanically filtered, is continuously returned from mechanical filtering structure (78) through conduit (80) to main tank (73).</p> |
